Behrman, Robert. „Structural Measurement Of Military Organization Capability“. Research Showcase @ CMU, 2014. http://repository.cmu.edu/dissertations/373.
Der volle Inhalt der QuelleAnnotation:
This research presents a structural model of the effect of the organization of military units upon their capability. This research is oriented towards a more complete understanding of military capability and policy decisions about the structure and development of military forces. We identify the types of national and military policy decisions that claims of military capability inform, and find that there are five distinct types of capability claims relevant to military policy. We show how these types of capability claims are logically related to each other, but have different premises, predicates, and standards of proof. We find that one of these types of claims, General Organization Capability Claims, ties together the various military policy decisions. The remainder of this research shows how these capability claims can be formally structured based on military doctrine and structurally evaluated using a network-science based model. The interaction between the structural elements of a military organization (personnel, materiel, and information) and the things it is supposed to do (military tasks) can be represented and analyzed with network science methods, and represents a type of general organization capability claim. We present a method for representing policy decisions about unit structure and tactical doctrine. We then develop two versions of a structural model of capability–one that links the individual elements of an organization to the tasks it performs; another that considers the capacity of a set of organizations to meet a set of requirements. We show that network statistics of organizations represented off of authoritative, rather than observational, data are still consistent with network science findings but require interpretation. We also show how alternate methods of aggregating organizations can expand the utility of the capability measurement. This research presents five new contributions to the fields of military policy analysis and network science–(1) a taxonomy of military capability claims, (2) a meta-network model of doctrinal organization and task data, (3) a structural model of organization capability, (4) a structural model of organization capacity, and (5) a network-based method integer programming method.

Measurement System Analysis helps, along with statistical methods, provide deep knowledge about the capability of a company’s measurement system. Through a better understanding of how measurement systems perform, companies can base decisions on facts to promote quality work. This study examines the capabilities of Measurement System Analysis and examines how well a test bench performs while testing motors at Bosch Rexroth AB in Mellansel. The study examines both the repeatability and the reproducibility of the measurement system, i.e., the variability that occurs when the same operator is doing repeated measurements on the same motor and when different operators perform measurements on the same motor. Bosch Rexroth AB manufactures high torque hydraulic motors. The case study covered the motor type CA 50, which is the most produced motor today at the company. The tests were made at one of the two existing test benches. The DMAIC method within Six Sigma was selected to get a structured workflow in the case study. Three parameters were examined for the motor type CA 50 – high pressure, external leaks, and cleanliness – and touched on Destructive Testing. It was clear from the Measurement System Analysis that the operators did not have a significant impact on the variability of the motor tests for any of the three parameters. The precision of the measurement system differed between the parameters. Concerning the parameter high pressure, the measurement system could be considered to be acceptable, but with room for improvement. The parameter external leaks showed an excellent measurement system with strong margins. The parameter cleanliness, however, showed an unacceptable measurement system. The capability study regarding the same three parameters showed different results. The parameter high pressure showed a decent capability (C_pk^ = 1.17). Parameter external leaks showed a high capability (C_pk^ = 1.17), but cleanliness showed a poor capability (C_pk^ = 1.09, 1.0 respectively 1.13) for the three different particle sizes 4µm, 6µm and 14µm. This thesis resulted in four main suggestions for improvement concerning both the test bench facility and motor type CA 50. The recommendations could help reduce the uncertainty in the measurements of the parameter cleanliness and the precision of the parameter high pressure. Furthermore, the thesis presents a suggestion on how outliers of parameter high pressure might be handled and suggestions for adjusted tolerances on the parameter external leaks.

Since the deregulation of power systems was started in 1989 in the UK, many countries have been motivated to undergo deregulation. The United State started deregulation in the energy sector in California back in 1996. Since that time many other states have also started the deregulation procedures in different utilities. Most of the deregulation market in the United States now is in the wholesale market area, however, the retail market is still undergoing changes.
Deregulation has many impacts on power system network operation and control. The number of power transactions among the utilities has increased and many Independent Power Producers (IPPs) now have a rich market for competition especially in the green power market. The Federal Energy Regulatory Commission (FERC) called upon utilities to develop the Regional Transmission Organization (RTO). The RTO is a step toward the national transmission grid. RTO is an independent entity that will operate the transmission system in a large region. The main goal of forming RTOs is to increase the operation efficiency of the power network under the impact of the deregulated market.
The objective of this work is to study Internet based Wide Area Information Sharing (WAIS) applications in the deregulated power system. The study is the first step toward building a national transmission grid picture using information sharing among utilities. Two main topics are covered as applications for the WAIS in the deregulated power system, state estimation and Total Transfer Capability (TTC) calculations. As a first step for building this national transmission grid picture, WAIS and the level of information sharing of the state estimation calculations have been discussed. WAIS impacts to the TTC calculations are also covered. A new technique to update the TTC using on line measurements based on WAIS created by sharing state estimation is presented.Ph. D.

The advanced handling of uncertainties arising from a wide range of sources is fundamental in quality control and dependability to reach advantageous decisions in different organizational levels of industry. Es-pecially in the competitive edge of production, uncertainty shall not be solely object of estimation but the result of a systematic management process. In this process, the composition and utilization of proper in-formation acquisition systems, capability models and propagation tools play an inevitable role. This thesis presents solutions from production system to operational level, following principles of the introduced con-cept of uncertainty-based thinking in production. The overall aim is to support transparency, predictability and reliability of production sys-tems, by taking advantage of expressed technical uncertainties. On a higher system level, the management of uncertainty in the quality con-trol of industrial processes is discussed. The target is the selection of the optimal level of uncertainty in production processes integrated with measuring systems. On an operational level, a model-based solution is introduced using homogeneous transformation matrices in combination with Monte Carlo method to represent uncertainty related to machin-ing system capability. Measurement information on machining systems can significantly support decision-making to draw conclusions on man-ufactured parts accuracy, by developing understanding of root-causes of quality loss and providing optimization aspects for process planning and maintenance.QC 20181015

Rechargeable lithium-ion batteries (LIBs) have generated a shift in the automotive industry towards electric vehicles (EVs) instead of vehicles powered by fossil fuels. As a result, the demand for LIBs is only expected to grow in the future due to an increased demand for passenger EVs. Consequently, LIB manufacturers have to increase their production to meet the increasing demand. Northvolt is a Swedish LIB manufacturer founded in 2016, aiming to start the production of LIBs at the Northvolt Ett factory in Skellefteå during 2021. The Northvolt Ett factory will be one of the largest battery plants in Europe, supplying battery cells for both commercial and domestic use. Poorly manufactured battery cells can potentially cause hazardous events, such as fires or explosions, further supporting the need for high quality batteries. Consequently, requirements from customers and industry standards are high in terms of product quality control through e.g. measurement system analysis (MSA), statistical process control (SPC), and capability analysis. Furthermore, previous research has highlighted issues during commissioning and ramp-up of production, potentially occurring at Northvolt Ett. The purpose of this study has been to describe how high-quality production can be ensured and maintained during and after commissioning. The study has been conducted as a qualitative case study at Northvolt Ett, focusing on qualification of the coating process. The basis for the study was to examine previous research on quality assurance from other industries, analyze automotive standards, and gather learnings from the pilot production at Northvolt Labs in Västerås. Unstructured interviews were conducted with Northvolt staff to understand what had previously been done related to quality assurance for Coating. The learnings from Northvolt Labs highlighted a clear focus on preventive actions, such as establishing a Design-FMEA, Process-FMEA, and a Control Plan for the coating process. However, room for improvement was identified in terms of process improvement and control, since the lack of SPC has yielded unreliable results from the performed capability analysis. In addition, previous research has shown that preventive actions should be combined with actions for process improvement to reach full-scale production quickly. Thus, recommendations have been made for Northvolt to implement a clear strategy for product qualification through SPC and capability analysis, as a complement to the preventive actions. The recommendations include specific propositions for validation of the coating process and a general framework for process validation through MSA, SPC, and capability analysis. The presented recommendations can help Northvolt perform successful commissioning of the processes at Northvolt Ett and can also be useful for process validation in other manufacturing industries.Laddningsbara litium-jon-batterier (LIB:s) har skapat en omställning i bilindustrin mot eldrivna fordon istället för fordon som drivs av fossila bränslen. Som en konsekvens väntas efterfrågan av LIB:s bara att öka i framtiden på grund av en ökad efterfrågan på eldrivna passagerarfordon. LIB-tillverkare måste därför öka sin produktion för att möta den växande efterfrågan. Northvolt är en svensk LIB-tillverkare som grundades 2016, med sikte på att starta produktionen av LIB:s vid fabriken Northvolt Ett i Skellefteå under 2021. Fabriken Northvolt Ett kommer att vara en av de största batterifabrikerna i Europa och leverera battericeller för både kommersiell och privat användning. Dåligt tillverkade battericeller kan potentiellt orsaka allvarliga händelser som bränder eller explosioner, vilket vidare stödjer behovet av batterier med hög kvalitet. Till följd av detta är kraven från standarder och tillverkare inom bilindustrin höga i termer av kvalitetskontroll av produkter genom t.ex. mätsystemanalys (MSA), statistisk processtyrning (SPS), och duglighetsanalys. Vidare visar tidigare forskning på problem som kan uppstå under driftsättning och upprampning av produktion, vilka potentiellt kan uppstå för Northvolt Ett. Syftet med denna studie har varit att beskriva hur högkvalitativ produktion kan säkerställas och upprätthållas under och efter driftsättning. Studien har genomförts som en kvalitativ fallstudie vid Northvolt Ett med fokus på kvalifikation av coating-processen. Utgångspunkten för studien har varit att undersöka tidigare forskning inom kvalitetssäkring från andra industrier, analysera standarder från bilindustrin, och hämta in lärdomar från pilotproduktionen vid Northvolt Labs i Västerås. Ostrukturerade intervjuer genomfördes med anställda på Northvolt för att öka förståelsen för vad som tidigare gjorts relaterat till kvalitetssäkring för Coating. Lärdomarna från Northvolt Labs visade ett tydligt fokus på förebyggande åtgärder, som upprättande av en Design-FMEA, Process-FMEA, och en kontrollplan för coating-processen. Dock identifierades ett förbättringsområde inom åtgärder för processförbättring och kontroll, då avsaknaden av SPS har genererat opålitliga resultat från den genomförda duglighetsanalysen. Vidare har tidigare forskning visat att förebyggande åtgärder borde kombineras med åtgärder för processförbättring för att snabbt uppnå fullskalig produktion. Rekommendationer har därför tagits fram till Northvolt för att implementera en tydlig strategi för produktkvalifikation genom SPS och duglighetsanalys, som ett komplement till de förebyggande åtgärderna. Dessa rekommendationer inkluderar specifika förslag för validering av coating-processen samt ett generellt ramverk för processvalidering genom MSA, SPS, och duglighetsanalys. De presenterade rekommendationerna kan hjälpa Northvolt att genomföra en framgångsrik driftsättning av processerna på Northvolt Ett och kan även vara användbara för processvalidering i andra tillverkningsindustrier.

In South Africa, the majority of youth entering emerging adulthood find themselves in a protracted struggle to access further education, training or to secure their first decent job. The purpose of this multi-case study is to deepen the understanding of how capability measurement approaches and tools can empower marginalized youth to better understand their aspirations and map their way through emerging adulthood and out of poverty. This research aims to deepen the understanding of youth's experience utilizing 'Poverty Stoplight'; a poverty measurement and capability building instrument that utilizes a self-assessment survey and mentorship methodology. The researcher utilized a youth-focused participatory approach in conducting focus groups and in-depth one-on-one interviews across five marginalized communities in the Western Cape to gain insight into their experience using the tool, their ability to envision their future selves and develop their aspirations. What emerged from the data were insights into the youth's aspirations, the perceived enabling factors and impediments towards their aspirations and their experiences utilizing Poverty Stoplight. This process enabled youth to genuinely reflect and assess their situation, and have the opportunity to define their aspirations. Overall the Poverty Stoplight programme was experienced as empowering by participants, with several implications for the programme pertaining to data accessibility, communication, mentorship and solution sharing, as well as the importance of youth-specific participatory approaches. Aligned to this, the findings yielded several recommendations pertaining to providing support and enabling opportunities for emerging adults to realise their aspirations. Despite the limitations of this research, this study is relevant for stakeholders in South Africa and globally as it examines the critical issue of youth development, with a focus on the ability of young people to attain their aspirations. Further, it analyses the capability measurement approach as a means to ensuring young people can better understand and plot their way out of poverty, making the most of their individual capabilities and attributes within the broader structural and systemic challenges they face. This exploration of practical tools and methodologies being developed and utilized by pioneering organisations in the South African context provides empirical evidence of the merit of such approaches, with recommendations on how tools and approaches can even better serve the needs of youth. Further, longitudinal research is merited into the use of such capability measurement approaches to empower youth and the further use of participatory methodologies.

Hand and finger force data are used in many settings, including industrial design and indicating progress during rehabilitation. The application of appropriate work design principles, during the design of tools and workstations that involve the use of the hand and fingers, may minimize upper extremity injuries within the workplace. Determination and integration of force capabilities and requirements is an essential component of this process. Available data in the literature has focused primarily on whole-hand or multi-digit pinch exertions. The present study compiled and examined maximal forces exerted by the fingers in a variety of couplings to both enhance and supplement available data. This data was used to determine whether finger strength could be predicted from other strength measures and anthropometry. In addition, this study examined whether exerted finger forces could be estimated using surface electromyography obtained from standardized forearm locations. Such processes are of utility when designing and evaluating hand tools and human-machine interfaces involving finger intensive tasks, since the integration of finger force capabilities and task requirements are necessary to reduce the risk of injury to the upper limbs.Forces were measured using strain gauge transducers, and a modification of standard protocols was followed to obtain consistent and applicable data. Correlations within and among maximum finger forces, whole-hand grip force, and anthropometric measures were examined. Multiple regression models were developed to determine the feasibility of predicting of finger strength in various finger couplings from more accessible measures. After examining a wide variety of such mathematical models, the results suggest that finger strength can be predicted from easily obtained measures with only moderate accuracy (R2-adj: 0.45 - 0.64; standard error: 11.95N - 18.88N). Such models, however, begin to overcome the limitations of direct finger strength measurements of individuals.
Surface electrodes were used to record electromyographic signals collected from three standardized electrode sites on the forearm. Multiple linear regression models were generated to predict finger force levels with the three normalized electromographic measures as predictor variables. The results suggest that standardized procedures for obtaining EMG data and simple linear models can be used to accurately predict finger forces (R2-adj: 0.77 - 0.88; standard error: 9.21N - 12.42N) during controlled maximal exertions. However, further work is needed to determine if the models can be generalized to more complex tasks.

Os ensaios laboratoriais para avaliação técnica ou estudo de material de irrigação envolvem a medição de diversas grandezas, bem como o monitoramento e controle das condições de ensaio. Qualquer sistema de medição e controle naturalmente apresenta instabilidades que podem afetar a qualidade dos resultados de ensaio, implicando em aumento da incerteza no processo de medição. A implementação do Controle Estatístico de Qualidade pode ser promissora para detecção de causas externas de variação, avaliação da variação máxima permitida aos dados de um processo e discriminação das principais componentes de variabilidade de um sistema de medição. Nesse sentido, considerando a hipótese de possibilidade de aprimoramento da qualidade dos resultados de ensaios, a presente pesquisa teve por objetivo utilizar técnicas de controle estatístico de qualidade e análise de sistemas de medição para avaliar o grau de adequação de bancadas de ensaio de emissores de microirrigação, aperfeiçoar os sistemas de medição e controle adotados nas bancadas e diagnosticar a porcentagem de contribuição dos fatores inerentes aos sistemas de medição e controle na variabilidade total das medidas de vazão em ensaios de uniformidade. A pesquisa foi conduzida no Laboratório de Ensaios de Material de Irrigação (LEMI/INCTEI/ ESALQ/USP). Foram elaborados gráficos de controle de Shewhart, média móvel exponencialmente ponderada (MMEP), além de índices de capacidade para o processo de medição da pressão de ensaio, monitoramento de temperatura da água e vazão, consideradas como as variáveis características da qualidade para ensaios de determinação das curvas de vazão em função da pressão de entrada e uniformidade de vazão de emissores de microaspersão e gotejamento. Além disso, realizou-se estudo de repetitividade e reprodutibilidade (Gage RR) do sistema de medição da vazão, para o qual foram utilizadas 10 repetições, sob três turnos de trabalho (manhã, tarde e noite), com 13 emissores na bancada de microaspersão e 25 emissores na bancada de gotejamento. Não houve influência do turno de trabalho nas medidas de vazão obtidas e o aprimoramento do processo de ajuste da pressão de ensaio pela implantação de um controlador proporcional integrativo-derivativo (PID) ao ensaio de microaspersores foi suficientemente detectado pela aplicação dos gráficos de controle. A pressão e temperatura da água se mantiveram estáveis durante cada ensaio, e não foram identificadas causas não aleatórias de variabilidade na rotina de ensaios. O processo de controle e medição da pressão, para as duas bancadas, foi classificado como\"excelente\" quanto ao desempenho e capacidade de se manter entre os limites de especificação e centralização em relação ao valor de referência (alvo desejado). Como esperado, a variabilidade entre emissores foi a componente de maior contribuição na variância total da vazão, correspondendo a 95,47% e 96,77% para microaspersão e gotejamento, respectivamente. A repetitividade e reprodutibilidade do sistema de medição de vazão (Gage RR) foi \"aceitável\" para as duas bancadas, com as respectivas contribuições de 4,53% e 3,23%, em relação à variância total, associados às incertezas do Gage RR.Laboratory tests for technical evaluation or irrigation material testing involve the measurement of various greatnesses, as well as monitoring and control of test conditions. Any measurement and control system naturally presents instabilities that can affect the quality of the test results, resulting in increased measurement uncertainty. The implementation of the Statistical Quality Control may be promising for detecting causes of variation non-random, evaluation of the tolerance permitted to data of the process and breakdown of the main variability components of a measuring system. In this sense, considering the hypothesis of possibility of improving the quality of test results, the present study aimed at using statistical quality control techniques and measurement systems analysis to assess the reliability of test benches of microirrigation emitters, improve measurement and control systems adopted in the benches and to diagnose percentage of contribution of the factors inherent in the measurement and control systems in the total variability of flow measurements on uniformity tests. The research was carried in Laboratório de Ensaios de Material de Irrigação (LEMI/INCTEI/ ESALQ/USP). Shewhart control charts were developed, exponentially weighted moving average (EWMA), and capability index for the process of measuring the test pressure, temperature monitoring of water and flow, regarded as the quality variables for determination the flow curves as a function of inlet pressure and uniformity of flow for microsprinkler emitters and drip. In addition, it was made study of repeatability and reproducibility (Gage RR) of flow measurement system for which were used 10 repetitions in three work shifts (morning, afternoon and evening), with 13 emitters in the microsprinkler\'s bench and 25 emitters in the drip bench. There wasn\'t influence of the work shift in the obtained measures for flow and the improvement of the adjustment process of the test pressure for the implementation of the integrative-derivative proportional controller (PID) to microsprinklers test was sufficiently detected by control charts. The pressure and water of temperature remained stable during the tests and weren\'t identified non-random causes of variability in routine tests. The process control and measurement of pressure was classified \"excellent\" to performance and capability to remain in the range of specification and centralization in relation to the reference value (desired target), to the two benches. As expected, the variability between emitters was the greater contribution component in the total variance of flow, corresponding to 95.47% and 96.77% for microsprinkler and drip, respectively. The repeatability and reproducibility for flow measurement system (Gage RR) was \"acceptable\" for the two benches, with the contributions respective of 4.53% and 3.23% relative to the total variance, associated with uncertainties of Gage RR.

Approved for public release; distribution is unlimitedThe United States Coast Guard (CG) is currently using Microsoft products as the main means of completing Manpower Requirement Determinations (MRDs). This does not allow the CG to produce reliable, repeatable, and defendable determinations nor does it assist in meeting the 5-year evaluation cycle of 128 unit types. For the CG to ensure human capital decisions are scientifically based and become more efficient in MRD completion, the CG will transition to a MRD system that automates much of the process. To develop the system, this thesis argues and recommends the use of an Iterative Incremental Development (IID) process model to deliver capability in increments driven by schedule. The model consists of seven iterations with a six-month duration to complete all iteration activities. In addition, this thesis proposes a three-tier system’s architecture to act as a blueprint of the target system. The three-tier architecture consists of a data, application, and presentation layer. The results of this thesis is a process model and systems architecture that will guide the CG’s development team through development and acquisition of the system while enabling user feedback throughout the process and reducing risk.

The purpose of this master thesis work is to design a device that measures the loudness of sound for different frequencies. This device is divided in three parts; a microphone that captures the sound, one A/D converter that samples the sound and one FPGA which analyse the data using an FFT algorithm.
LEDs connected to the FPGA are used to indicate different output levels. A db(A) filter is applied that weights each frequency, before the different outputlevels are measured for each frequency.
This system is supposed to be a subsystem to a larger system that is developed in a company. However, because of the risk that competitors might be able to guess the next product move of the company, the company is anonymous in this report. All the components used are paid for by the company and in return the company gets an idea of the complexity of the system and a basis for future design decisions.

Industry often requires, in a variety of processes, the measurement of deformation induced in a solid object by mechanical stress. One such process is during the manufacture of very large scale integrated circuits (VLSI). During this process a substrate is coated with a thin film to protect the micro circuitry formed on the substrate. Due to the differences in thermal expansions between film and substrate, mechanical stresses can develop which may lead to deformation of the substrate surface. Any deformation of the substrate surface will result in mechanical stress in the interconnections of the circuitry, which could result in severe damage to the operation of the circuit. Different measurement techniques are available to measure the spherical deformation of substrates, with the latest known technique being a combination of a laser beam deflection and light scattering techniques. Many of the existing techniques reveal shortcomings, one of which is a 2-dimensional scanning capability with a minimum of moving components. Another shortcoming is the incapability of previous techniques to calculate the relative error which the measuring technique induces into the results. The aim of this study has been to develop an electro-optical system embodying the successful principles of these techniques in a system which will eliminate the shortcomings and produce results in excess of those previously recorded. In this work, we have concentrated on discussing the development of a system which will produce in situ real time monitoring of mechanical stresses in a solid. The system includes the minimization of system induced errors through the calculation of error voltage gains, and the introduction of a 2-dimensional scanning capability to determine the true position of the laser beam without prior knowledge of the initial substrate curvature. A four-quadrant position sensitive detector (PSD) with relevant Lab View software and programs were also introduced into the system.

The latest development in the measurement techniques has resulted in fast improvements in the instruments used for measurement of various electrical quantities. A common problem in such instruments is the automation of acquiring, retrieving and controlling the measurements by a computer or a laptop. In this study, nodal resistance measurement (NRM) system is developed to solve the above problem. The purpose of this study is to design and develop a compact electronic board, which measures electrical resistance, and a computer or a laptop controls the board. For the above purpose, surface nodal points are created on the surface of the sample electrically conductive material. The nodal points are connected to the compact electronic board and this board is connected to the computer. The user selects the nodal points, from the computer, between which the NRM system measures the electrical resistance and displays the measured quantity on the computer.

Innovation is one of the most important factors behind today´s global economic growth and prosperity. In the current economic climate, increasing global competition and rapidly changing environment, an organisations ability to innovate is regarded as a key factor for success. It is widely accepted that creating new processes, products and procedures are vital for productivity and growth in all sectors. The literature on innovation measurements areas and utilities is voluminous and diverse. Assessing and measuring the complex conditions that influence a firm’s innovation capability is a challenging task, due to the inconsistency, inaccessibility, and complexity of measures. An integrative and holistic innovation capability assessment framework should include all aspects of innovation. This study attempt to address this gap, the lack of a holistic innovation capability assessment framework (HICAF) in project-based firms, by (a) reviewing the literature on innovation, innovation assessment, and measurement areas (b) through a qualitative case study exploring the factors promoting innovation in project-based firms (c) integrating the findings into a holistic assessment framework (d) generating items, in form of a statement, to address the underlying construct of each identified factor (e) applying the proposed framework within an organisation and statistically validating the instrument to achieve item homogeneity. Internal consistency reliability estimates have been utilized to produce a final framework consisting of 57 statistically validated items and eight theoretically grounded categories with 19 corresponding factors promoting innovation, also called enablers, in technology-orientated project-based organisations. In addition to the identified literature findings, the case study resulted in two new enablers, time management, and quality, which are not necessarily specific for project-based organisations, rather specific for the observed organisation. The performed case study is insufficient for determining whether there are any specific enablers for project-based organisations. The advantages of HICAF lies in its simplicity due to practical applicability in a large scale and facilitates managers to diagnose the organisation and recognize true symptoms to then apply appropriate treatment and remedies. A frequent application of HICAF can also help to study the effect of specific treatment and remedies in relation to innovation capability.

Modern power systems are now stepping into the post-restructuring era, in which utility industries as well as ISOs (Independent System Operators) are involved. Attention needs to be paid to the reliability study of power systems by both the utility companies and the ISOs. An uninterrupted and high quality power is required for the sustainable development of a technological society. Power system blackouts generally result from cascading outages. Protection system hidden failures remain dormant when everything is normal and are exposed as a result of other system disturbances. This dissertation provides new methods for power system vulnerability analysis including protection failures. Both adequacy and security aspects are included. The power system vulnerability analysis covers the following issues: 1) Protection system failure analysis and modeling based on protection failure features; 2) New methodology for reliability evaluation to incorporate protection system failure modes; and, 3) Application of variance reduction techniques and evaluation. A new model of current-carrying component paired with its associated protection system has been proposed. The model differentiates two protection failure modes, and it is the foundation of the proposed research. Detailed stochastic features of system contingencies and corresponding responses are considered. Both adequacy and security reliability indices are computed. Moreover, a new reliability index ISV (Integrated System Vulnerability) is introduced to represent the integrated reliability performance with consideration of protection system failures. According to these indices, we can locate the weakest point or link in a power system. The whole analysis procedure is based on a non-sequential Monte Carlo simulation method. In reliability analysis, especially with Monte Carlo simulation, computation time is a function not only of a large number of simulations, but also time-consuming system state evaluation, such as OPF (Optimal Power Flow) and stability assessment. Theoretical and practical analysis is conducted for the application of variance reduction techniques. The dissertation also proposes a comprehensive approach for a TTC (Total Transfer Capability) calculation with consideration of thermal, voltage and transient stability limits. Both steady state and dynamic security assessments are included in the process of obtaining total transfer capability. Particularly, the effect of FACTS (Flexible AC Transmission Systems) devices on TTC is examined. FACTS devices have been shown to have both positive and negative effects on system stability depending on their location. Furthermore, this dissertation proposes a probabilistic method which gives a new framework for analyzing total transfer capability with actual operational conditions.

Includes bibliographical references.This report starts by describing the background research and work that had already been done on the UCT scanning tunneling microscope (STM). This system is being developed in the Department of Electrical Engineering at UCT. It goes on to describe the continuation of the research work that was done for this dissertation on the STM at UCT. The work was originally started by Dr. Tapson for his PhD (1994). and continued by the author for his MTech degree in ) 997 and 1998. The work was temporary discontinued from May 2000 till August 2002 to enable the author to work as a contract engineer at the Institute of Physics in Basel, Switzerland to learn more about the construction of probe microscopes. The new work evolved around the need to implement scanning tunneling potentiometry (STP) capability in the new STM. This capability should give the end-user the capability of looking at the sub-surface structure of any material on a sub-micron scale. The basic STP function must be implemented in two dimensions in the plane of the specimen. The STM tip is then used as a highly localized voltmeter to sense what the potential distribution is at that point on the surface. The potential information that is obtained is then used to plot two images of the potential distribution over the surface in the X and Y directions. The topographic information is obtained in the usual way from the STM scan. This method gives three collocated imagesas the result and a better understanding of the surface structure is obtained in this way. The penetration depth of the potential scan can be varied by adjusting the frequency of the applied AC signal in the X and Y directions. This use of the skin effect should allow the end user to obtain slices of the surface at various penetration levels of the specimen. These slices will give a picture of what happens from the surface up to a certain penetration depth. The interpretation of these images could be very difficult because the skin effect does not stop at a defined penetration depth. Only the 3 dB point is defined, which means that sub surface structures below the 3 dB point will also have an influence on the obtained image. During the course of the research new hardware and scanning software was implemented to enable the error-free acquisition of new data. This entailed splitting the existing XY controller into three separate parts namely a Communications interface, and two STP measurement boards. This was suggested as one of the conclusions of the MTech thesis results. The PC software stayed the same but for a change in the array size, that holds theacquired data. This was again changed after the work experience in Basel and is explained in chapter 6.

The Global Positioning System (GPS), a space-based system, employs dozens of satellites to provide location determination and navigation services around the world. However, due to the constraints to the power consuming and long-distance transmission, the strength of the GPS signal received on the mobile device is weak. Errors of the detection of the line-of-sight (LOS) propagated components of the signals are expected to be high if the users are in urban areas or in buildings, since obstacles in the surrounding environments could attenuate the LOS propagated components of the GPS signals significantly, but might upfade the multi-path components (constructive multi-path effect). Therefore, GPS should be replaced by other techniques for providing localisation services in urban areas or, especially, in indoor environments. Among all the candidates, received signal strength (RSS) location fingerprint based positioning systems attract great attentions from both the academia and industry. Usually, a time-consuming and labour-intensive site survey to collect dozens of training samples of RSS from access points (APs) in range on every reference position (RP) in the area of interest is required to build the radio map (RM), before the localisation services could be provided to users. The purpose of the thesis is to reduce the workload involved in the site survey while providing accurate localisation service from two aspects, as shown as follows. Firstly, the quantity of the training samples collected on each RP is reduced, by taking advantage of the on-line RSS measurements collected by users to calibrate the RM. The on-line RSS measurements are geo-tagged probabilistically by an implementation of particle filter to track the trajectories of the users. The employed particles in estimation of the users’ states are initialised by a supervised clustering algorithm, propagated according to the analysis of the data sourcing from inertial measurement units (IMUs), e.g., walking detection, orientation estimation, step and stepping moments detection, step length detection, etc., and corrected by the wall constraints. Furthermore, the importance weights of the particles are adjusted to reduce the negative influence of the multi-clustered distribution of the particles to the on-line localisation accuracy, by applying the on-line RSS-based localisation results when significant users' body turnings are detected. The final results confirm that the accuracy of the localisation service with the RM calibrated by the method proposed in this thesis is higher than the previously proposed approach taking advantage of expectation maximisation algorithm. Secondly, a semi-automatic site-survey method which takes advantage of a route-planning algorithm and a walking detection module to recognise automatically the index of the RP for the current site-survey task, inform the system automatically of the start/end of the process of the task on the current RP and switch automatically to the following RPs on the planned route for the following tasks. In this way, human beings' intervention to the site-survey process is greatly reduced. As a result, the errors made in the site-survey tasks, such as incorrect recognition of the index of the RP for the current task which is highly likely to occur when the technicians get absent-minded in the work, misoperations to start/end of the task for collecting RSS samples on the current RP at wrong time moments, forgetting to notify the system of the fact that the technician has moved on to the next RP, etc., are avoided. The technicians no longer feel bored or anxious in the process of fulfilment of site-survey tasks, and the working efficiency and robustness of the RM could be also improved.

Electromagnetic compatibility (EMC) standards for an accredited test laboratory require that the measurement uncertainty of the measuring instruments be characterized. The CISPR 16-4 standard gives guidance to the magnitude of this uncertainty, but no method of characterization. This thesis describes a method to perform this characterization on a conducted emissions measurement system, taking advantage of full system analysis techniques to reduce the uncertainty to exceptionally low levels. In addition, a framework is introduced whereby uncertainty can decomposed into its constituent parts such that the laboratory operator can identify methods to improve the systems performance.

The Broad Institute of MIT, Harvard, and the Whitehead Institute, contains the world's highest-throughput genome sequencing center, which contributed approximately one third of the sequence for the Human Genome Project (HGP) completed in 2003. Broad's Genome Sequencing Operations Group has acquired a cost leadership position within the genome sequencing industry through its competitive advantage in developing and implementing innovative, industrial-scale process technologies. Yet, this group has the opportunity to further improve its position as a leader in the genome sequencing industry by improving its operations capability to levels of world-class manufacturing organizations in other industries. At the highest level, Broad's management team sponsors Leaders for Manufacturing (LFM) internships as a long-term investment to improve the operations capability of its Genome Sequencing Group. Employees at Broad ultimately learn about leading-edge operations tools and principles through their exposure to LFM interns and their projects.
(cont.) While these investments have led to some significant operations improvements, the Genome Sequencing Group has not yet transformed into an organization that strives for operational excellence in the same way that world-class manufacturing organizations do. Thus, the primary goal of this thesis is to provide a methodology to transform the Genome Sequencing Group's culture and catalyze the development of its operations capability. Just as DNA contains the genetic instructions specifying the biological development of an organism, a performance measurement system contains the instructions that guide the development of an entire organization. Performance measurement systems provide the explicit incentive and accountability mechanisms necessary to motivate employees to achieve operational excellence. While training programs and exposure to leading-edge thinking are valid approaches to achieving operations improvements, these limited initiatives are simply not enough. The implementation of a performance measurement system at Broad would significantly enhance the results of Broad's current approach to developing the operations capability of its workforce.

Using isolation and noise immunity techniques, this thesis designs and constructs a low cost measurement system to safely and accurately measure high voltage, high frequency pulses in harsh EM environments. High voltage pulses apply to medical, plasma, and food industries. The difficulty of accurately measuring high voltage pulses continues to pose an issue. Measuring high voltage systems can cause damage to the system, the measurement system, and the user. High voltage and high frequency pulses create a harsh environment of electromagnetic fields that can disrupt the circuitry of the measurement system and harm the user. Implementing isolation from the high voltage system protects the measurement and user. An ideal pulse has sharp rising and falling edges, introduction high frequencies that prove difficult to sense and characterize. The measurement system requires a sufficiently large bandwidth to accurately measure the pulse edges. Commercial off the shelf pulse measurement systems such as oscilloscopes and multimeters cost thousands of dollars. Cheaper but simpler designs fail to provide isolation for safety. The measurement system in this thesis addresses all of these issues, allowing people to measure and characterize high voltage pulses.
Technologies used in this measurement network include optocouplers, transimpedance amplifiers, and analog-to-digital converters. The development process describes design, simulations, characterizations, construction, testing, and troubleshooting. Simulations show expected operations of components and characterizations assist in determining performance parameters of the system. Testing involves performing a low voltage test and a high voltage test and identifying limitations of the design. Finally, this thesis suggests future work to improve performance and lower cost of the measurement system.

Machine tools need to be tested to check they behave correctly while machining. A bigger production (capacity), improving the accuracy in final products (quality) or reducing costs are some of the main goals. Reducing the maintenance of the machines, their nonproductive time and a higher quality of the final parts, have a strong influence in the costs. Even machines built to the same specification present different properties and behaviours, which leads into a reduction of the flexibility when it comes to move operations among them. This study is focused on the measurement and modelling of four machine tools (M1, M2, M3 and M4), with same specifications, from the static point of view. Methods used to measure all these properties are the circular tests under loaded conditions, with the device Loaded Double Ball Bar (LDBB), which measures positional accuracy and static stiffness. Different pressures (0.5, 1, 3, 5, 6, 7 bar) and locations for the LDBB have been used. After the tests were performed, all the machines shown good properties with the detail of M4, which had a lower stiffness than the other three ones due to its table attachments.Maskinverktyg måste testas för att kontrollera att de beter sig korrekt vid bearbetning. En större produktion (kapacitet), förbättra noggrannheten i slutprodukterna (kvalitet) eller sänka kostnaderna är några av huvudmålen. Att minska underhållet av maskinerna, deras icke-produktiva tid och en högre kvalitet på de slutliga delarna har ett starkt inflytande i kostnaderna. Även maskiner konstruerade för samma specifikation presenterar olika egenskaper och beteenden, vilket leder till en minskning av flexibiliteten när det gäller att flytta verksamheten bland dem. Denna studie är inriktad på mätning och modellering av fyra verktygsmaskiner (M1, M2, M3 och M4), med samma specifikationer, ur statisk synvinkel. Metoder som används för att mäta alla dessa egenskaper är de cirkulära testerna under laddade förhållanden, med enheten Loaded Double Ball Bar (LDBB), som mäter positionsnoggrannhet och statisk styvhet. Olika tryck (0,5, 1, 3, 5, 6, 7 bar) och platser för LDBB har använts. Efter testerna visade alla maskiner goda egenskaper med detaljerna i M4, som hade en lägre styvhet än de andra tre på grund av dess bordsfästanordningar.

The study is to discuss the measurement system capacity analysis of Gauge Block Comparator. The purpose is improving the quality requirement of calibration instruments to ensure the stability of quality system while calibrating. The total variance arisen from measuring instruments includes: the variety of measuring environment, the precision of measuring equipment, the experience of measuring staff and the specifications of the workpiece under test. The variance arisen from these sources of variation must be made into data and chart to show the measuring capability of measurement system. The main items in measurement system analysis are: stability, bias, linearity, repeatability and reproducibility. Different experimental models are designed according to different characteristics. After running the data, we can estimate these data with some statistical methods which include: hypothesis test, one-sample t test, two-sample t-test, linear regression analysis, analysis of variance (F test). Then we use statistical software (MINITAB) to do the reliability analysis and to list the analysis charts. Finally, we determine if the measuring capability of instrument is qualified to provide a reference for instrument calibration personnel and quality assurance workers. This analysis method helps us check if instruments are abnormal in quality system. Using the analysis method to determine the measurement system can more clearly show the assurance in quality system.

NoThe analysts need timely and accurate information to conduct proactive action over complex situations. Typically, there are thousands of reported activities in real time operation, although, to direct the analysts attentions to the most important one, researchers have designed multiple levels of situational awareness (SWA). Each process lends itself to ranking the most important activities into a predetermined order. According to our best knowledge, less attention has been given to the performance evaluation with regards to the prioritisation stage. Specifically, the performance metric, "The Activity of Interest Scores" has not considered corner cases of different situational assessments needs and configurations. Originally, it had not been designed for measuring the capability of the SWA system. In this paper, we have proposed a new performance metric, as well as a guidance case study for measuring the ranking capability of SWA systems. Our initial result shows that, The Ranking Capability Score has provided an appropriate scoring scheme for different ranking capabilities of SWA systems.

According to the Worldwide CMMI Implementation Report issued by the Software Engineering Institute (SEI) at the Carnegie Melon University up to September 2008, there have been 111 organizations implementing CMMI are certified in Taiwan and it was ranked the seventh in the world. From another angle, Taiwan can be ranked the first in the world if we consider the population density in. Whereas, there has not been sufficient evidences showing how those organizations performed after being certified by CMMI. This research is based on the data of the public listed Information Service Companies between 2002 and 2008 taken from Taiwan Economic Journal (TEJ) and those who have been certified on Level 3 of CMMI from the CMMI Project website from the Bureau of Industries of the Ministry of Economy. This research covers 12 organizations who have, or not, being certified by CMMI. The research is to analyze the efficiency value based on the BBC model of DEA. Four different approaches are to be made for Mann-Whitney U statistics. In each approach, we will try to utilize three combinations with different inputs and outputs. The purpose of this research is to create a useful reference for the government on CMMI implementation. It can also be a reference for those organizations who intend to implement CMMI in the future. The research leads us to the conclusion that being certified by CMMI Level 3 is not related to the efficiency improvement in those organizations and the possible reason could be most of them are certified in recent years and there has not been sufficient time for them to show the performance.

The measurement system analysis (MSA) is very important for quality improvement. A capable measurement system can be accurately to measure observed data. Normally, the evaluation standard of MSA by QS-9000 is used to judge the measurement capability. However, the current QS-9000 or ISO/TS16949 only refer to the acceptable range of P/T value, the relationship between Process capability index and P/T value had been rarely proposed. The thesis discusses the acceptable range of P/T value under satisfying customer’s Cpk requirement which considering process accuracy and precision. Firstly, the functional relation between Cpk and P/T value, Ca is derived. The approximate lower confidence limit of Cpk is used to determine the acceptable range of P/T value under observed Cpk values. To utilize the reasonal range to conduct a two factor experiment to evaluate if measurement system variation error is within the range. Finally, a case study is derived the implementing step of evaluating measurement capability.

Process capability indices have been widely used in the manufacturing industry. Those capability indices, quantifying process potential and performance, are important for any successful quality improvement activities and quality program implementation. Most research works related to process capability analysis have assumed no gauge measurement errors. However, the quality of data on the process characteristics relies very much on the gauge measurement. Conclusions about capability of the process just only based on the single numerical value of the index are not reliable. In our research study, we conduct the performance of the estimators of the indices, Cp, Cpk, Cpu and Cpl with gauge measurement errors, and present adjusted confidence interval bounds and critical values for capability estimation or testing purpose of those indices with unavoidable measurement errors. Our research would help practitioners to determine whether the factory processes meet the capability requirement, and make more reliable decisions.

In recent years, lots of research papers with process capability indices have been proposed for assessing process performance in the manufacturing industry, but have been comparatively neglected for those with the presence of measurement errors. In this paper, we consider the process capability measure based on the incapability index Cpp (Greenwich and Jahr-Schaffrath (1995)) in the presence of gauge measurement errors. We investigate the effects of measurement errors on the estimation of Cpp. In addition, the critical values are derived and the upper confidence bounds for true Cpp are constructed for testing process capability. This methodology is useful for the practitioners to judge the present process capability and ensure the process yield when measurement errors are unavoidable.

The purpose of this paper is to establish the experimental method to evaluate the measurement capability of CMM by bias, linearity, stability, repeatability and reproducibility. According to the probing of reference, we use the length measure by CMM to evaluate the measurement capability of CMM. According to the definition of bias, linearity, stability, repeatability and reproducibility of length measure by CMM, Time, workpiece and operator are the experimental factors and the response is the measuring value of block gauge by CMM. Because randomization the time factor is not possibility, so we use the time factor as block. In each block, use split-plot design to obtain the measuring value of block gauge by CMM. Analysis the measurement of the block gauge by CMM, the accuracy and precision of length measure of CMM are very well. Accept the bias, linearity, stability, and reproducibility of length measure of CMM. The repeatability of length measure of CMM is 0.1*10-7 inch2, extreme small.

How can firms create sustainable competitiveness? This question has long been the hottest issue in the field of strategic management. From the theory of competitive advantage（Porter, 1980; Spanos and Lioukas, 2001）, an “outside-in” perspective to first consider the industry environment which firms lie in, resources-based view（Wernerfelt, 1984, 1989; Barney, 1991）, an “inside-out” perspective which concern the specific resources and capabilities of firms to dynamic capability theory（Winter, 1987; Teece et al., 1997）which consider the flexible capability to reconfigure resources and capabilities to response the dynamic environment are theories with multiple perspectives trying to answer this question. Dynamic capability theory emphasizes the ability of a firm to develop new capabilities in response to shifts in its external environment, as a significant source of competitive advantage. Three factors can determine a firm’s dynamic capabilities: they are firms’ “process”, “position” and “path”. The whole framework of dynamic capability theory mainly integrate organizational learning, evolutionary theory and resource-based view, compared with other theories, it seems can be better used to explain the dynamic process of firms. There have been many researches trying to examine this theory or further develop applications in practice, but these studies seem exist some problems about the content of theory and measurement. In order to solve these problems, we want to explore the content of the theory through deep literature review, build up the measurement model of dynamic capability and then test the theory. Our research has three different points in methodology from past researches. First, we adapt the perspectives of cross and vertical section to analysis the position of dynamic capability theory in the field of strategic management and its true meaning. Based on the result of deep literature review, we develop the observed variables of the dimensions of dynamic capability. Second, we quantify the content validity. By gathering the validity rating of scholars of each question, we calculate the Aiken content validity coefficient s and homogeneity reliability coefficients, which can be objective standard for us to decide if each question is valid. After deleting those invalid questions, we form our dynamic capability scale. Third, We adapt the statistic technique of structural equation model to test the construct validity and reliability, which has never been used in dynamic capability related researches before. We gather 25 scholars’ validity rating of 71 questions that we develop. After calculating the Aiken content validity coefficients and homogeneity reliability coefficients, we form the final dynamic capability scale after deleting 8 invalid questions. We then use the scale to measure the dynamic capability of firms. We conclude that the measurement model of dynamic capability that we develop do fit the data that we collect, which means all the observed variables that we develop can measure the latent variable effectively and consistently. So at last our research has developed a dynamic capability scale with reliability, content validity and construct validity.

Under the competition for globalization and Customer-oriented approach, strengthening the effectiveness of the overall industry value chain is one of major research topics including the related topics of each sub-chain (i.e., chains of design, manufacturing, and service). However, service chain is near to the market, and the design and manufacturing are based on customer requirements. Considering service quality and customer satisfaction and taking them as a front-end business objective, the interaction index and interaction capability for service chain to interact with other sub-chains should be concurrently developed. The learning benchmarking of service chain then can not only be selected, but also interaction capability training plan can be made to promote the efficiency of enterprise value chain. In this research, the interaction index of service providers, represent the service chain, to interact with other sub-chains, were deployed to study the related interaction capability training planning. According to the literature study, the interaction capability of service providers was determined after confirming the interaction index. The performance of service providers then can be measured by Data Envelopment Analysis. Also, the learning benchmarking can be selected for other service providers to learn. Certainly, each service provider will know their own insufficiency of interaction capabilities. A series of the training courses then can be planned for strengthening the related skills. According to the cases simulated to demonstrate the necessary procedures, the feasibility and the ability to analyze the insufficiency of interaction capability were shown. A feasible training plan can be determined to improve the performance of service providers. The overall effectiveness of the enterprise value chain then can be enhanced.

The purpose of this thesis is to devise a linear actuator with displacement measurement capability. The designed coil-set may function as a displacement sensor (i.e., a linear variable difference transformer, LVDT), an actuator (i.e., a solenoid), or both, using different driving circuits. Under proper feedback control, the device can serve as a compact linear servo motor. We first test the sensing and actuation capability of the coil-set. To enable the coil-set to have both functions at the same time, we isolate the ac measurement signal from the dc actuation powers by adding capacitors and inductors to the circuit. However, experimental results show that the ac measurement signals are attenuated by the inductance. The system is then modified by an LC resonant circuit that maximizes the intensity of the 16 kHz measurement signal. Secondly, we design a band-pass filter to replace the capacitor that serves as a high-pass filter. Unlike the high-pass filter, the band-pass filter lets the 16 kHz signal through to the measurement IC (AD598) without passing the switching signals in PWM control. Finally, we build a closed-loop control system using an 8-bit microcontroller, that integrates both functions of actuation and measurement of the coil-set. An additional LVDT sensor is mounted on the coil-set to examine the performance of the mini linear servomotor.

Gauge measurement errors (GME) began to play an important role in many types of manufacturing industries because it would affect the estimation and assessment of the process capability. In recent years, the issue of process capability assessment in the presence of GME for cases with symmetric tolerances was investigated enthusiastically. However, even processes with symmetric tolerances are very common in practical situations, cases of asymmetric tolerances also occur in manufacturing industries. In this dissertation, generalized confidence interval (GCI), sampling distribution (SD), and modified sampling distribution (MSD) approaches are applied to assess the performances of processes with asymmetric tolerances in the presence of the GME. To examine and compare the performance of the proposed approaches, an exhaustive simulation under various conditions was conducted. The conclusion is that the proposed approaches appear quite satisfactorily for assessing process performance with asymmetric tolerances in the presence of GME in terms of the Coverage Rate (CR) and the Average Value of Lower Confidence Bound (AVLCB). Examples are presented to illustrate the applicability of the proposed approaches in real factory condition.

The textile industry in Taiwan has been developed rapidly with information technologies, which change from labor-intensive and technique-intensive to knowledge-intensive. The competing strategy has been promoted to the way of approaching customers’ needs with multiplex and fast service rather than repeated emphasis on high quality and low price. Without offending already-existed competing such as reducing cost, quick response, the quality of service, and the quality of product, accentuations of closely relationships between provider and customers has become the at least prerequisite term of a firm. The development of e-Business has become an unavoidable trend for the textile industry. At first, this study purposes to find an appropriate indicator about textile e-Business level meausement through bibliographies research.By means of the throwing of a poll, and apply the six factors of this study, which includes “Information technology”、“Organization operation and strategy”、 “Internal processes flow”、“External processes flow”、“Creating new reality and Adding vaule”and “Supply chain management”, the e-Business levels of the overall textile industry and its upstream, midstream, and downstream aspects. The discussions of business co-operations Relationship capability and the adaptation capability to technological process change are also given. The results of data analysis are: 1. In the textile industry,the level of “Information technology” is the superior one.The next are “Organization operation and strategy”、” Internal processes flow”and “Supply chain management”.The level of “External processes flow” and “Creating new reality and Adding vaule” are the worst that need to strengthen. 2. In the upstream industry,the level of “Information technology”, “Internal processes flow”、 “External processes flow”、 “Creating new reality and Adding vaule”and “Supply chain management” are superior to the overall txtile industry,the level of “Organization operation and strategy” is the worst that’s needs to strengthen.In the midstream industry,the level of “Organization operation and strategy”is the superior one,the “Information technology”、 “Internal processes flow” and “External processes flow” are the worst that needs to strengthen.In the downstream, the “Creating new reality and Adding vaule”and “Supply chain management” is the worst that need to strength. 3. The best performance of adaptation capability is midstream industry. In the contrast; the worst performance is downstream industry. The best performance of relationship capability is upstream industry. In the contrast; the worst performance is downstream industry. 4. The adaptation capaibility has the strongest positive relationship with the extent of “Creating new reality and Adding vaule”.And the relationship capaibility has the stromgrst positive relationship with the extent of “Supply chain management”.
