Abstract:
Thesis: S.M., Massachusetts Institute of Technology, Department of Mechanical Engineering, 2014.Cataloged from PDF version of thesis.
Includes bibliographical references (pages 56-64).
Tissue engineering for cartilage repair is a promising approach for improving the healing of articular defects, as biomaterials and growth factors can be supplied directly to a focal lesion. However, integrating neo-tissue with native cartilage to provide mechanical and biological continuity at the interface remains a challenge due to the limited regenerative capacity of the tissue. In an effort to improve integration, enzyme treatments were investigated as a means of functionally grafting engineered tissue to native tissue. Using an in vitro model of defect repair, this study develops a repair strategy that employs both a hydrogel (KLD) functionalized with HB-IGF-1 and an enzyme pre-treatment of the cartilage surrounding a defect to provide local delivery of the pro-anabolic factor and allow for functional integration of cartilage neo-tissue. Results indicate that the rate of proteoglycan synthesis was elevated in cartilage explants into which KLD pre-mixed with HB-IGF-1 had been cast; both the explants that had received the enzyme pre-treatment and those that were left untreated had a two-fold increase compared to the explants exposed to non-functionalized KLD. Similarly, GAG content was favorably elevated in the chondrocyte-seeded gels exposed to the growth factor. While GAG was depleted selectively within the inner annulus of the explants receiving the pre-treatment, no negative effect was observed on the rate of proteoglycan synthesis or GAG content compared to that in explants left untreated. Further, mechanical tests suggest that the combination of KLD functionalized with HB-IGF- 1 together with an enzyme pre-treatment is able to increase interfacial strength between engineered tissue and native matrix. Taken together, a repair strategy combining an enzyme pre-treatment of a defect with a peptide hydrogel functionalized with pro-anabolic HB-IGF-1, as developed in this study, is a promising approach for enhancing integration. Stimulating the surrounding tissue with the growth factor and allowing for functional integration of newly synthesized matrix promotes continuity at the interface between new and native tissue, ultimately improving the overall quality of repair.

Puwanun, Sasima. "Developing a tissue engineering strategy for cleft palate repair." Thesis, University of Sheffield, 2014. http://etheses.whiterose.ac.uk/7175/.
Abstract:
The most common craniofacial birth defect is cleft defect with an incidence of 1.7:1000 live births. The current treatments involve many steps of surgical procedures and cause morbidity at the donor site when harvesting bone for filling the gap defect. It may be possible to treat cleft palate defects by tissue engineering strategies using osteoprogenitor cells on a biodegradable distensible electrospun scaffolds to form the hard palate. The aims of this project are to select the suitable cell sources, materials, chemical supplementation, and mechanical conditions to enhance matrix mineralization for repairing the bone part of a cleft palate. Human jaw periosteal cells (HJPs), human mesenchymal stem cell derived from bone marrow (hBMSCs), and human embryonic stem cell mesenchymal progenitor (hESMPs) used in this project showed osteogenic potential by depositing calcium deposition on both monolayer and 3D constructs with the requirement of Dex in the culture media. Electrospun poly(?-caprolactone) scaffolds (PCL) are a suitable temporary extracellular matrix for bone tissue engineering. Vascular endothelial growth factor (VEGF) is an important protein for new blood vessel formation. The VEGF secretion was reduced by Dex supplemented culture media in 3D culture, whereas, it was delayed in the monolayer culture. All cell types responded to oscillatory fluid flow (OFF) by using a standard see-saw rocker to stimulate osteogenic differentiation. The cells were more sensitive to OFF when they were supplemented with Dex for enhancing calcium deposition both in monolayer culture and 3D culture and the strongest effect was at the top surface of the scaffolds. The composite nano-hydroxyapatite PCL electrospun scaffold can enhance matrix mineralization compared to the standard PCL scaffold, but there were no additional effects of OFF on these scaffolds. A tri-layer PCL scaffold could support and separate two different cell types (human dermal fibroblasts and human osteoprogenitor cells: both hESMPs and hBMSCs) and also allow osteogenic differentiation for 28 days. The novel tri-layer PCL electrospun membrane developed here is a promising scaffold for tissue engineering for cleft palate repair. Tissue engineering strategy could benefit treatment cleft palate treatment compared to the current treatments (autologous bone graft from iliac crest) to promote bone formation at the defect area and allow normal development of facial structure in the future.

Frampton, Matthew. "Using Dialogue Acts in dialogue strategy learning : optimising repair strategies." Thesis, University of Edinburgh, 2008. http://hdl.handle.net/1842/2381.
Abstract:
A Spoken Dialogue System's (SDS's) dialogue strategy specifies which action it will take depending on its representation of the current dialogue context. Designing it by hand involves anticipating how users will interact with the system, and/or repeated testing and refining, and so can be a difficult, time-consuming task. Since SDSs inevitably make understanding errors, a particularly important issue is how to design ``repair strategies'', the parts of the dialogue strategy which attempt to get the dialogue ``back-on-track'' following these errors. To try to produce better dialogue strategies with less time and effort, previous researchers have modelled a dialogue strategy as a sequential decision problem called a Markov Decision Process (MDP), and then applied Reinforcement Learning (RL) algorithms to example training dialogues to generate dialogue strategies automatically. More recent research has used training dialogues conducted with simulated rather than real users and learned which action to take in all dialogue contexts, (a ``full'' as opposed to a ``partial'' dialogue strategy) - simulated users allow more training dialogues to be generated, and the exploration of new dialogue contexts not present in an original dataset. As yet however, limited insight has been provided as to which dialogue contextual features are important to include in the MDP and why. Indeed, a full dialogue strategy has not been learned from training dialogues with a realistic probabilistic user simulation derived from real user data, and then shown to work well with real users. This thesis investigates the value of adding new linguistically-motivated contextual features to the MDP when using RL to learn full dialogue strategies for SDSs. These new features are recent Dialogue Acts (DAs). DAs indicate the role or intention of an utterance in a dialogue e.g. ``provide-information'', an utterance being a complete unit of a speaker's speech, often bounded by silence. An accurate probabilistic user simulation learned from real user data is used for generating training dialogues, and the recent DAs are shown to improve performance in testing in simulation and with real users. With real users, performance is also better than other competing learned and hand-crafted strategies. Analysis of the strategies, and further simulation experiments show how the DAs improve performance through better repair strategies. The main findings are expected to apply to SDSs in general - indeed our strategies are learned and tested on real users in different domains, (flight-booking versus tourist information). Comparisons are also made to recent research which focuses on handling understanding errors in SDSs, but which does not use RL or user simulations.

BONKAT, BARNABAS NANPAK. "ANALYTICAL PROCEDURE FOR EVALUATING ROADWAY UPGRADING STRATEGY FOR LOW-VOLUME HIGHWAYS." Diss., The University of Arizona, 1985. http://hdl.handle.net/10150/187926.
Abstract:
The purpose of this research was to develop a simplified analytical procedure for determining the optimal timing for upgrading low-volume roads in developing countries. Most roadway upgradings from gravel to surface treated and to asphaltic concrete are carried out when total transport cost on a road becomes high as a result of high traffic and the consequent rapid deterioration of the roadway. Adequate timing of upgrading strategies ensures effective use of resources and lower total transport cost. This study examined existing systems, models, and approaches for estimating total transport cost components. An analytical procedure was then developed using a decision-tree concept to delineate all possible upgrading strategies within a plan period. The decision-tree concept depicts all the possible upgrading strategies within a plan period with decisions on roadway upgrading made at certain decision intervals. The total transport cost of the upgrading strategies is evaluated to establish the optimal strategies and traffic warrants for improving a roadway surface. A computer program PVMNT was written to facilitate the computation of the total transport cost. A case study was presented to demonstrate the application of the analytical procedure. The case study revealed interesting results on the changes of optimal upgrading strategies with changes in base traffic volume and growth rate. However, general conclusions could not be drawn based on the results of the case study. These results, as well as the analytical procedure, should be of interest to engineers responsible for providing low-volume roads in developing countries.

Abstract:
NoMany industrial systems such as aircrafts, ships, manufacturing systems, etc. are required to perform several missions with finite breaks between missions. Maintenance is only available within the breaks. Due to the limitation of resources, all components in the system may not be maintained as desired. The selective maintenance problem helps the decision makers figure out what critical components to select and how to perform maintenance on these components. This paper studies the selective maintenance for multi-state series-parallel systems with the benefit of repairing multiple components simultaneously. Both time and cost savings can be acquired when several components are simultaneously repaired in a selective maintenance strategy. As the number of repaired components increases, the saved time and cost will also increase due to the share of setting up between components and another additional reduction amount from the repair of multiple identical components. A non-linear optimization model is developed to find the most reliable system subjected to time and cost constraints. Genetic algorithm is used to solve the optimization model. An illustrative example will be provided.

Abstract:
Current global efforts for energy conservation and optimization are focused on improvements in energy supply and production systems, and on encouraging the adoption of energy-efficient devices and equipment. However, systematic assessments of economic and technical implications when adopting energy-efficient alternative systems in buildings have not yet been explored thoroughly. The uncertainty about the consequences of investing in alternative energy-efficient systems has led to a prolonged utilization of obsolete building systems (underperforming HVAC systems, inefficient lighting systems, badly maintained and equipment, and so forth). This has led to overall poor energy efficiency, creating considerable burden on the building operation budget.
This research discusses the procedure for formulating an investment strategy to improve existing building energy performance. The approach is suitable for large building portfolios where a plethora of potential refurbishment interventions can be considered. This makes our approach especially suited for use on university campuses and most of this report will focus on that particular application utilization protocols especially for use on campuses. This investment model only looks at the energy related savings versus investments; it is well understood that the ultimate selection of the optimal set of improvement options of a portfolio will be determined by additional considerations, such as overall value, occupant satisfaction, productivity improvements, aesthetics, etc. Nevertheless, many campus managers are confronted with the question how much energy they can save with a given investment amount. This is exactly what our approach helps to answer.
The investment optimization strategy is implemented in software "InvEnergy," which systematically calculates the costs and benefits of all possible building-technology pairings, taking uncertainties in the saving/investment calculations and estimates into account. This tool empowers decision makers in facility management to make complex investment decisions during continuous building commissioning.

Abstract:
Thesis (MPA)--Stellenbosch University, 2012.ENGLISH ABSTRACT: research study was about finding the right sourcing strategy that would work effectively for the South African Police Service (SAPS) garages. Its purpose was to help the SAPS garages deal strategically and effectively with their work load while repairing the SAPS vehicles, as the current evidence indicated that the garages might not have sufficient capacity to cope with the volume of repairs they were receiving. The research was structured as a case study design, in which personal interviews were held with SAPS garage managers, SAPS strategy drivers (Head Office) and executive managers at the City of Cape Town, Western Cape Provincial Government Fleet, and Passenger Rail Agency of South Africa (PRASA). To follow up on these initial one-on-one interviews, a further questionnaire comprising similar, information-gathering questions was sent out to various SAPS garage managers to elicit more detailed information on the circumstances of their individual garages. A literature review, which formed the basis of the study, explains the sourcing strategy, and explores different sourcing options including how to make the best sourcing decision. In this study, three models of sourcing strategy were considered, and were supported by the case study of the City of Cape Town, Western Cape Provincial fleet management, and PRASA. This study has proved that what the different authors have written and recommended about in-sourcing and outsourcing can still be considered in conjunction with the current legislative and policy framework. The cost analysis was conducted in order to be able to assess which option would be the more expensive between in-sourcing and outsourcing. The fundamental finding of this research was that the SAPS garages could not handle all the work they were receiving, as they did not have the capacity, for various reasons, to deal with the volume of vehicle repairs that were coming in, and that the variety of sourcing strategies at the different garages were not effectively reducing the backlog. There was no clear sourcing strategy in place from the National office to guide the garages. From these findings, the recommendation is that the big garages should handle all the services and minor repairs including some major repairs, with the majority of the major repairs being outsourced to service providers, while the smaller garages should focus on services and minor repairs only, and outsource all major repairs. The vehicles that are not within a 30km radius of the SAPS garages must be directly outsourced to providers using the RT46 contract, or similar arrangement. Further research studies are needed regarding the demographic structure of the garages, and also regarding the effectiveness and efficiency of the actual running of the garages. A balance then needed to be found between in-sourcing and outsourcing, whilst ensuring that the garages were operating efficiently and outsourcing responsibly.
AFRIKAANSE OPSOMMING: Die navorsingstudie is gedoen om die effektiefste en geskikste verkrygingstrategie vir die voertuigwerkswinkels van die Suid-Afrikaanse Polisiediens (SAPD) te bepaal. Die doel was om die werkswinkels te help om strategies en effektief te werk gegewe hulle werkslading, aangesien huidige bewyse getoon het dat hulle nie voldoende kapasiteit daarvoor het nie. Die navorsing is gestruktureer as ’n gevallestudie, waartydens persoonlike onderhoude met SAPD-werkswinkelbestuurders, SAPD- strategiese drywers (Hoofkantoor), en uitvoerende bestuurders van die Stad Kaapstad, die Wes-Kaapse Provinsiale Regering-vloot en die passasier-spooragentskap van Suid-Afrika (PRASA) gevoer is. Ter opvolging van die oorspronklike individuele onderhoude is ’n verdere vraelys gebruik waarin soortgelyke vrae aan SAPD-werkswinkelbestuurders gestel is om meer inligting aangaande die toestand van hulle werkswinkels te bekom. ’n Literatuuroorsig, wat die basis gevorm het van die studie, verduidelik die verkrygingstrategie en ondersoek verskillende verkrygingsopsies, asook hoe om die beste verkrygingsbesluite te neem. In hierdie studie is drie verkrygingstrategiemodelle oorweeg, wat ondersteun is deur die gevallestudie van die Stad Kaapstad, die Wes-Kaapse Provinsiale Regering-vlootbestuur en PRASA. Die studie het bewys dat dít wat die onderskeie outeurs oor in- en uitkontraktering bevind en aanbeveel het, steeds oorweeg behoort te word, aangevul deur die bestaande wetgewing en beleidsraamwerk. Die kosteontleding is gedoen om te bevestig watter in- of uitkontrakteringsopsies die effektiefste sou wees. Die fundamentele bevinding van hierdie navorsing is dat die SAPD se voertuigwerkswinkels tans nie al die werk wat hulle ontvang, kan hanteer nie, omdat hulle om verskeie redes nie die nodige kapasiteit het om die groot aantal voertuie wat inkom, te herstel nie. Die uiteenlopende strategieë wat die onderskeie werkswinkels volg sover dit uitkontraktering betref, verminder ook nie die agterstand nie. Daar is nie ’n duidelike verkrygingstrategie van die nasionale kantoor wat riglyne aan die werkswinkels verskaf nie. Die aanbeveling na aanleiding van hierdie bevindinge is dat die groot werkswinkels al die versienings en kleiner herstelwerk, met inbegrip van sekere groot herstelwerk, moet hanteer, terwyl die kleiner werkswinkels moet fokus op versienings en kleiner herstelwerk, en alle groot herstelwerk moet uitkontrakteer. Indien voertuie buite ’n 30 km-radius van ’n SAPD-werkswinkel is, moet sodanige herstelwerk uitgekontrakteer word deur gebruik te maak van die RT46-kontrak, of ’n soortgelyke reëling. Verdere navorsingstudies is nodig oor die demografiese struktuur van die werkswinkels, asook die doelmatigheid en effektiwiteit betreffende die werklike bedryf van die werkswinkels. ’n Balans moet gevind word tussen in- en uitkontraktering, terwyl daar verseker moet word dat die werkswinkels effektief bedryf word en uitkontraktering op ’n verantwoordelike wyse geskied.

Thesis, Linnéuniversitetet, Institutionen för marknadsföring (MF), 2021. http://urn.kb.se/resolve?urn=urn:nbn:se:lnu:diva-104721.
Abstract:
Background: Brands that decide to publish sexist advertisements can generate issues for the company, as well as the perception the consumer has of the brand can become negative. This as consumers form attitudes towards the brand’s delivered communication which influence the overall evaluation the consumer has towards the brand. It is therefore of importance for brands to understand how to respond to sexist advertisements that have been published in order to determine the created negative publicity, where one given approach is to apply one of the image repair strategies. Purpose: The purpose of this paper is to describe how a brand’s image repair strategy towards its sexist advertisement affects consumers’ attitudes. Methodology: This research undertook a qualitative research approach with a descriptive nature. In order to ensure that the advertisements were classified as sexist and that the image repair strategies correspond with the brand’s responses according to the public, a pre-study was conducted through five semi-structured interviews. For the main study eight semi-structured interviews were conducted with both men and women as participants within the ages of 19-56 years old. Findings: The thesis identified that consumers' attitudes were affected by the four components: correspondence between advertisement and response, authenticity in the response, clarity regarding what actions to take and pre-knowledge of the brand. These components are therefore of importance for companies to take in consideration when responding towards sexist advertisements that they have sent out. Conclusion: Regarding the image repair strategies it was found that the responses given through the strategies of denial, evasion of responsibility and reduction of offensives lacked in all detected components. Furthermore, mortification as a strategy was not perceived as negative regarding the responses, however it still lacked the components. Corrective action was the only strategy where consumers' attitudes did not become negative towards the correspondence and authenticity in the response. However, all five strategies lacked clarity regarding what actions to take.

Jenvald, Mattias, and Mikael Hovmöller. "Reducing Delays for Unplanned Maintenance of Service Parts in MRO Workshops : A case study at an aerospace and defence company." Thesis, Linköpings universitet, Produktionsekonomi, 2020. http://urn.kb.se/resolve?urn=urn:nbn:se:liu:diva-167203.
Abstract:
Service parts sometimes break down unexpectedly and require maintenance. The irregular nature of the need for this type of maintenance makes forecasting difficult and unreliable. Saab currently experiences problems with long delays when performing unplanned maintenance of service parts used in the two models of Gripen aircraft, Gripen C and Gripen D. These delays are source of monetary waste, as late delivery of maintained service parts results in Saab having to pay penalty fines to the customers. The purpose of this master thesis was to analyze data collected during a case study at Saab in Linköping, and suggest improvements for how to reduce these delays. This study focused on analyzing what caused the delays, and how the information provided by the customers can be used by the operative planners at the Maintenance, Repair \& Overhaul (MRO) workshops in order to be more efficient. The data was collected during the case study using semi-structured interviews of 16 people working with the current system, as well as by collecting historical data from an internal database at Saab. This data was analyzed in parallel with a literature study of relevant research related to service parts supply chains, MRO workshops, and unplanned maintenance operations. The analysis showed that there were four types of interruptions of maintenance; Internal stock-out of spare parts, internal stock-out of sub-units, external delays at the Original Equipment Manufacturer (OEM), and internal equipment breakdowns. A root cause analysis found that the four root causes of delays were: Saab does not have any contracts that incentivizes their OEM's to deliver on time. The data from the technical report is not used to provide the operative planners with information about incoming orders. The MRO workshops do not have a standardized system for prioritizing maintenance of service parts. The MRO workshops currently lacks a method for predicting certain types of machine breakdowns.

Abstract:
This thesis aims at explaining two different methods by which failure analysis can
be conducted . The two methods were used in two totally different circumstances.
One was the failure study conducted at the Petrie Mill of Australian Paper and the
other was a study of conveyor belt failures based on the author's experience at
Neyveli Lignite Corporation Limited. The bottom line is to stress the need for
separate strategies depending on the nature of industry or the machinery and the
importance of documenting the actual Failure Analysis however it may be done.
This will help in further development of the strategies and provide ideas for
newcomers in the field. Using the data obtained by applying strategy-1 Reliability
Analysis and Planned Replacement cost analysis can be conducted. Two
components selected by applying strategy-I were analysed using Relcode and are
included in this thesis. Three other major initiatives associated with this research are
Failure Recording and Spare Control system (FR&SC) for Petrie Mill, Belt
Condition Recording and Monitoring system(BEL TCON) and Conveyor Belt
Breakdown Maintenance Management flow chart for users of conveyor belts. All of

Abstract:
исертацію присвячено розробці раціональних рішень при ремонтних роботах технологічного устаткування в блочно-комплектному виконанні та підвищенню ефективності експлуатації об'єктів систем трубопровідного транспорту газу шляхом вибору раціональних стратегій технічного обслуговування. Для цього створено математичні моделі та проведені довготривалі експериментальні й аналітичні дослідження, які дають змогу визначити: раціональне розбиття блочно-комплектного устаткування на окремі елементи, вибір стратегій і режимів обслуговування, виділення передвідмовного (передаварійного) стану блоків, вузлів і деталей.Диссертация посвящена разработке рациональных решений при ремонтных работах технологического оборудования в блочно-комплектном исполнении и повышению эффективности эксплуатации объектов систем трубопроводного транспорта газа путем выбора рациональных стратегий технического обслуживания. Для этого созданы математические модели и проведены долговременные экспериментальные и аналитические исследования, позволяющие определить: рациональное разбиение блочно-комплектного оборудования (БКУ) на отдельные элементы, выбор стратегий и режимов обслуживания, выделение предотказного (предаварийного) состояния блоков, узлов и деталей. Предложенные стратегии технического обслуживания и ремонта позволяют увеличить наработки между отказами, уменьшить периодичность ремонтных работ, исключить ряд регламентных операций, и тем самым снизить трудоемкость, продолжительность и стоимость обслуживания. Для обеспечения надежности работы системы использованы методы повышения показателей надежности элементов технологического оборудования за счет планирования и проведения профилактических ремонтов. В данной работе рассмотрению подлежат три типа взаимосвязанных задач: рациональное расчленение БКУ на отдельные обособленные объекты (элементы) обслуживания и ремонта (I), выбор для каждого выделенного элемента рациональной стратегии и режима обслуживания и ремонта (И), определение целесообразности восстановления элемента на месте или на ремонтной базе, или списания (III). Это может быть решение задачи одного из типов при фиксированных решениях других задач (условно названных одномерным случаем) или общее решение двух задач различных типов при фиксированном решении задачи, осталась. Комплексное решение перечисленных задач на достижение глобального оптимума по выбранным критериям, в сущности, и определяет рациональную стратегию технического обслуживания и ремонта БКУ. При моделировании и расчетах стратегий и режима обслуживания блочнокомплектного оборудования магистральных газопроводов использовано распределение Вейбулла. Расчет проводился для двух состояний БКУ: исправного и предотказного. Задача выбора оптимального режима обслуживания БКУ магистральных газопроводов решалась как оптимизационная задача, позволяет минимизировать удельные затраты на обслуживание БКУ при ограничениях, наложенных на коэффициент готовности оборудования. На основе созданной модели технического обслуживания исследовано влияние средней наработки в исправном состоянии и средней наработки в предотказном состоянии на показатели эффективности обслуживания в блочнокомплектном исполнении. Предложены методики расчетов параметров эксплуатационной надежности объектов магистральных газопроводов и оптимизации их обслуживания, определения коэффициента готовности оборудования компрессорных станций и оптимизации средних удельных затрат на обслуживание и ремонт и планирования количества технических обслуживании компрессорных станций. По результатам исследований разработана схема пакета оптимизации. Проведена апробация предложенных методик оптимального планирования ремонтно-восстановительных работ в ПРТП "Укргазэнергосервис" подтвердила достоверность полученных результатов.

Abstract:
Appréhender les caractéristiques mécaniques du béton in situ est essentiel pour déterminer la capacité structurelle à la fois des structures existantes et des nouvelles constructions. La méthodologie récente d'évaluation de la résistance du béton dans une structure existante consiste à intégrer des techniques de Contrôle Non Destructif (CND) avec des mesures destructives (carottage) pour établir un modèle de conversion qui corrèle la résistance mécanique avec les mesures non destructives. Par la suite, le modèle de conversion est appliqué pour estimer la résistance mécanique locale à chaque emplacement de test en fonction des valeurs CND correspondantes.Le test du rebond (RH) et le test de la vitesse des ondes ultrasonores (UPV) sont largement utilisés pour estimer la résistance à la compression du béton. Cependant, l'exactitude des résultats obtenus par ces méthodes peut être influencée par divers facteurs. Pour atténuer ces effets, la combinaison stratégique de ces deux tests non destructifs offre un moyen efficace d'évaluer la résistance du béton dans les structures existantes. Par conséquent, l'objectif de cette thèse est d'analyser la méthodologie d'évaluation des structures en combinant des techniques non destructives et de fournir des recommandations pratiques qui peuvent améliorer la fiabilité de l'évaluation de la résistance in-situ du béton. À cette fin, un simulateur a été développé pour analyser la méthodologie d'évaluation non destructive en utilisant un vaste ensemble de données provenant de diverses sources, notamment des études in situ, ainsi que des données synthétiques générées.La principale contribution de cette étude est de proposer une nouvelle approche d'identification de modèle basée sur l'optimisation multi-objectifs pour prédire la résistance moyenne du béton et sa variabilité, en se basant sur la combinaison des mesures CND. Des simulations Monte Carlo ont été réalisées pour vérifier les performances en tenant compte de l'incertitude des mesures CND et de la variabilité du béton. Les résultats ont mis en évidence l'efficacité de la méthode multi-objectifs dans la détermination de la résistance moyenne et la variabilité de la résistance, par rapport à d'autres approches. De plus, cette approche innovante permet d'obtenir une précision améliorée dans l'estimation des propriétés du béton avec un nombre réduit de prélèvements par rapport aux méthodes traditionnelles.En outre, l'efficacité de diverses stratégies d'échantillonnage suggérées a été évaluée dans cette étude afin de sélectionner les emplacements optimaux pour les extractions de carottes. Une représentation précise et approfondie de la structure examinée peut être obtenue en choisissant soigneusement les emplacements de carottage. À travers des comparaisons approfondies, l'étude vise à déterminer le plan d'échantillonnage qui correspond le mieux aux objectifs spécifiques de l'évaluation de la résistance du béton. Il est suggéré d'utiliser l'échantillonnage4 par optimisation de la variance, qui semble être une alternative appropriée pour réduire les incertitudes inhérentes au processus d'évaluation non destructive [...]Understanding the in situ mechanical properties of concrete is essential for determining the structural capacity of both existing structures and new constructions. The recent methodology for assessing concrete strength in an existing structure involves integrating nondestructive testing (NDT) techniques with destructive measurements (coring) to establish a conversion model that correlates mechanical strength with nondestructive measurements. Subsequently, the conversion model is applied to estimate the local mechanical strength at each testing location based on the corresponding NDT values.The Rebound Hammer (RH) test and the Ultrasonic Pulse Velocity (UPV) test are widely used for estimating the compressive strength of concrete. However, the accuracy of the results obtained from these methods can be influenced by various factors. To mitigate these effects, the strategic combination of these two nondestructive tests provides an effective way to evaluate concrete strength in existing structures. Therefore, the aim of this thesis is to analyze the assessment methodology of structures by combining nondestructive techniques and to offer practical recommendations that can enhance the reliability of in-situ concrete strength. For this purpose, a simulator was developed to analyze the methodology of nondestructive assessment using an extensive dataset derived from various sources, including in-situ studies, as well as generated synthetic data.The primary contribution of this study is to propose a new model identification approach based on multi-objective optimization to predict the mean strength of concrete and its variability, based on the combination of NDT measurements. Monte Carlo simulations were carried out to check the performance by considering the uncertainty of NDT measurements and the variability of concrete. The results highlighted the effectiveness of the multi-objective method in determining both the average strength and the variability of strength compared to other approaches. Furthermore, this innovative approach enables enhanced accuracy in estimating concrete properties with a reduced number of cores compared to traditional methods.In addition, a thorough and accurate representation of the structure under examination can be achieved by carefully choosing the core locations. The efficacy of various suggested sample strategies has been evaluated in this study in order to select the optimal locations for the core extractions. Through these thorough comparisons, the study aims to discover the sampling plan that best aligns with the specific objectives of evaluating concrete strength. It is suggested to use variance sampling, which appears to be a suitable alternative for reducing inherent uncertainties in the nondestructive assessment process [...]

MBA Professional ReportApproved for public release, distribution unlimited
The purpose of this MBA professional report is to supplement the long and short range strategic development efforts of Fleet Readiness Center Southwest (FRCSW) by providing command leadership with an analysis of the current aviation maintenance, repair, and overhaul (MRO) industry to identify potential expansion opportunities for FRCSW. Strategy development is dependent upon a solid, current and complete industrial analysis. An industrial analysis includes, 1) a definition of the industry, 2) a description of external forces acting upon the industry, 3) a description of the industry structure and 4) an examination of the key success factors that benchmark the requirements for a firm to stay competitive in the industry. These analyses provide FRCSW with the information required to leverage their core competencies to indentify and capitalize on potential opportunities in the industry. This study identifies emerging trends, presents projected forecasts, identifies external forces on both the military aviation MRO industry and FRCSW, and discusses those factors that are key to long term success in the military aviation MRO industry. The conclusions present a number of opportunities for FRCSW to explore in their effort to remain the Navy's premier aviation depot.

MAODV is a multicast version of AODV, a routing protocol in wireless Ad Hoc network. MAODV can use the same control packets as in AODV. Although MAODV can provide more efficient path, its ineffective link repair scheme may drastically decrease PDR (Packet Delivery Ratio) in the situation of node mobility. This ineffective repair scheme also increases redundant control overhead and the probability of packet collision. In this Thesis, a new link repair scheme, MLRS (Multicast Link Repair Strategy), based on the MAODV, is proposed. The main characteristic of MLRS is Local Repair which allows upstream node of a broken link to do the repair. In Local Repair, we add the IP address of a broken downstream node in the control packet. The upstream node of a broken link will broadcast the control packet. Any node that receives the control packet can determine if its upstream link is broken. The similar Local Repair scheme is applied to the upstream node until a branch node is reached. We use a modified GRPH packet to deliver the information of hop count from a branch node to all the nodes on the multicast tree. A node that receives the GRPH can estimate the duration of Local Repair. For the purpose of evaluation, we use NS-2 to simulate the MLRS. We classify the multicast tree topology with different degrees to analyze their effects on the MLRS. The simulation results show that the MLRS increases the PDR of fast-moving nodes and it also reduces the control overhead. Moreover, the MLRS increases the PDR of broken nodes due to upstream node mobility.

The construction enterprise in Taiwan has been highly matured. Due to the tremendous housing-repair market, the construction enterprise require long-term operation so as to create great opportunity, therefore, it is necessary to develop to the direction of housing-repair. Nonetheless, study related to housing-repair mostly focus on technical or single operational management sides, few of those toward to integrated study. On the other hand, the difference between southern and northern Taiwan makes the theory completely unavailable. Besides, in the recent years, changes in Kaohsiung is rapid, the strategy for housing-repair operation also need to be adjusted simultaneously, and toward to the development of multiple management service side with the high-added value. This study is trying to understand the supply-demand condition and business operational mode to the residential housing-repair enterprise in Kaohsiung area, to induce operational strategy which could comply with actual need for the residential housing-repair enterprise, as a reference of those enterprises. Therefore, by utilizing the method of expert inquiry, this study conducted practical study referring to housing-repair enterprise supply & demand condition and issues of operational strategy. To the inquiry of housing-repair enterprise supply & demand condition, this study adopted reiterative statistics and Chi-Square Test of Homogeneity analysis. To the inquiry of operational strategy, analyzing by Analytic Hierarchy Process（AHP）. The result of this study shows, with respect to the demand, customers in Kaohsiung area focus the prize to the housing-repair service, and the frequency of housing-repair is about half year to two year. With respect to the supply, most popular marketing method is by reputation advertisement, and customers’ decision heavily relies on the performance of professional staff as well as on-site introduction. On the other hand, housing-repair companies emphasize service quality in term of internal management, especially taking customer relationship management as a marketing-oriented operational idea. And most companies have their own operational strategy, and regard the importance of that in normal condition. With respect to the operational strategy of housing-repair enterprise, including low cost service, high professional service and quality. With respect to integrated method, including promotion of management efficiency & effectiveness and customer’s satisfaction, shorten working period, reduction of manpower, lower material cost, lower wage cost, upgrade added value, promote customer’s value, convenience of on-call service, fast repair service, effective market separation, house evaluation, reasonable and transparent prize, selection of target market, accident prevention safety and ecologic construction, etc. The above methods could take as a reference to operational policy for the residential housing-repair enterprise in the southern Taiwan.

As smart phone industry competition is getting intensely, customers are not only demanding product appearance, functionality and quality increasingly but also demand after sale’s service quality and convenience more and more critical. After-sales service is not only just considered to be extra additional services, it became one of the considerations when customers buy product. Repair service is one of contact window of company and directly contact with customers, especially played an important role in customer satisfaction. In recent years, as the global economic downturn, companies in order to reduce the cost and provide better customer service quality and convenience, have adopted outsourcing to provide after-sales service, however, many of the outsourcers will difficultly to manage, as well as repair quality cannot be fully controlled, the company could not be more understanding the pulse of market changes and demand to cope with the design of future products. Therefore, this study will adopt hTC company case to explore, when hTC encounter after-sales service "cost reduction", hTC how to take into account the product "enhance the value".

As green supply chains (GSCs) have setting significant attention and concern, this study investigates the optimal pricing policy of a manufacturer in the green supply chain. From the perspective of a manufacturer, a distributor collect used products from customers, and it can repair the recycled products and sell to the market or sell them to the manufacturer for remanufacturing. In addition, the distributor sells the usable products purchased from the manufacturer and repaired products to the customers at the same time. Hence, this study establishes a two-stage game model, considering the interaction between a manufacturer and a distributor within the context of Bertrand duopoly and price competition to find the optimal pricing policy of the manufacturer. Next, a sensitivity analysis is conducted to discuss how different valuations for a repaired product, collection rate, market size, ratio of new product cost to remanufactured cost and repairing cost influence the manufacturer profit and distributor profit. The results show that (1) When the valuation for a repair product is higher, the manufacturer should increase the purchase price of collected products (2) The manufacturer should collaborate with the distributor to increase the collection rate to increase its profit (3) The manufacturer should choose product under the condition of low valuation for a repair product, low new product cost, and high repairing cost to increase its profit.

Green supply chain (GrSC) has been receiving increasing attention in recent years. As remanufacturers needs more supply of used products, the economic incentive is required to attract customers to return their used products. This study investigates the optimal subsidy and pricing policy of a manufacturer in the green supply chain, suggesting that the flow of returned items is variable, and is affected by the amount of subsidy provided by the manufacturer. Moreover, this study considers a distributor who sells the usable products, purchased from the manufacturer, and repaired products, produced by the distributor, to the customers at the same time. A two-stage game model is proposed to derive the optimal pricing policy of the manufacturer, considering the interaction between a manufacturer and a distributor within the context of price competition. A sensitivity analysis is conducted to discuss how manufacturer’s and distributor’s profit will be influenced by consumer valuation, return rate and the cost ratio of new product to remanufactured product.

Wireless Sensor Networks (WSNs) can be widely applied in many fields. However, the WSNs probably exists some coverage holes due to the random deployment of static sensor nodes. Otherwise, the energy exhausted of sensor nodes would cause the hole problem in WSNs. Furthermore, these holes will degrade the performance of wireless sensor networks (WSNs). Hence, how to discover the position of the holes and utilize the information to improve the performance of WSNs is a significant issue. For this purpose, we proposed a grid-based hole repair mechanism in WSNs. In grid-based architecture, we use the grid-based in Hole Recovering mechanism. The sink will calculate the position of the holes and allocate the mobile node based on W value to recover the hole according to grid recovering information. The research will baesd on this theroy to achieve the purpose of improving the performance of the WSNs.

Abstract:
M.Ing.The importance of maintenance in industry and specifically in the electrical distribution industry has never really been challenged. Maintenance has none of the glamour of other functions such as Marketing or Research, nor has it enjoyed close attention received by other aspects of business such as production and sales. Yet management remains painfully aware of the consequences and cost to the business when the maintenance job is not properly executed. What has, in recent years, exacerbated matters somewhat (in the electrical distribution business) is the reluctance of utility undertakings to invest heavily in a business that is to undergo a vast transformation arising from the creation of the National Electricity Regulator (NER). This will entail the amalgamation of some 400 plus different electricity distributors, by far the most in the guise of municipal undertakings, into a few Regional Distributors and Metro's. During this phase of uncertainty, the electricity departments of many municipalities have been allowed to deteriorate as maintenance and refurbishment funds were moved into other areas that would remain within the control of the municipalities. Eskom also has allowed, to a certain extent, its own distribution infrastructure to deteriorate over the last decade or so due to a focus being placed on the distribution and delivery of electric power to remote and informal settlement areas. Now on the eve of the re-organisation of the electricity supply industry into Regional Distributors and Metro's, the existing network infrastructures are far from being in an ideal situation to cope with the added business constraints to be placed on the supply industry under the scope of Regulation. This dissertation looks at an integrated maintenance strategy for one component of the electricity infrastructure namely, the distribution substation. The Electricity Supply Industry (ESI) is on the brink of vast changes that will reform the industry. Already there are cracks developing in the existing supply infrastructure resulting in power blackouts in several major centres. With the coming of the Regional Electricity Distributors, additional constraints will be placed on the supply industry. It is vital that maintenance management in the ESI start to work proactively in optimising maintenance to achieve a best return on hard gained funding in the coming years.

Different from terrestrial equipments (tanks and wheeled vehicles) and airborne crafts (planes or helicopters), the R & M (repair and maintenance) issues about naval vessels are profoundly related to their gigantic size, numerous operators, and thousands of various spare parts which individually have small quantity demand for logistic support. That is why the R & M of naval vessels is much more complicated. According to the Defense White Paper of 2009, the whole military force is going to be downsized. Meanwhile, the rescuing and relieving tasks for natural disasters have also been officially assigned to them. Therefore, the attendance rate of ships is increasing, which causes lower reliability and higher failure rate and consequently the rising R & M load. The dynamical complexity existing among the variables associated with R & M of naval vessels, which are non-linear, interconnecting and time-delaying, makes the system dynamics a very suitable theory for analyzing this kind of issue systematically. During the study, a model was built based on system dynamics. After reviewing related literatures and discussing with professionals in this field, the associated variables were defined and their casual diagrams were also established. We developed the stock-flow diagrams of three subsystems-- R & M process, man power, and material supply. Afterward these three subsystems were integrated into an R & M dynamical system model. Policy influence simulation and scenario design was carried out after basic tests confirming its validity. The results indicated that a higher R & M capacity could obviously reduce the number of ships stalled in shipyard and effectively increasing the discharge rate. Therefore we recommended the associated authority to boost R & M capacity by aggressive actions such as increasing the ratio of recruitment, building R & M knowledge management system and strengthening the education and training. For the follow-up research, we suggest more interviews with industrial personnel and experts, collecting R & M data for each type of naval vessel, deliberating the factors influencing the R & M from different aspects and appropriately defining system boundary in order to establish a model which is more similar to the real world. Therefore its simulated results can approach to the reality further, and the scenario analysis with conclusions induced from policy influence simulation can be more specific for the authorities.

This study employs a car managacturer’s “CSI Customer Response Scale” to discuss the prediction and prevention of customer complaints by maintenance and service personnel in automotive service plants while exploring the prediction and prevention of customer complaints by maintenance and service staffs from automotive service company. It seems that the services provided by maintenance or service staffs are not the same as what customers expect and concern. By comparing the processes identified by maintenance or service staffs are able to identify the problems of going wrong with the actual grievances from customers, the study aims to find the differences between them and give feedback to the staffs and reduce the probability of customer complaints. By forming an FMEA team consisting of experienced service specialists, the study utilizes the potential risks priority coefficient prediction on 15 items in service processes which may cause customer complaints. Then customer complaint cases for last three years are classified to confirm the differences between staffs and customers for rendering accurate recommendations to the company. As confirmed in this study, the predictions are consistent with the part of customer complaints, such as the quality of vehicles and service quality; as to the service processes in preparation and the customer demonstration facilities, the predictions are inconsistent with customer complaints. This result indicate that the predictions could help the company make sound adjustments on prevention measures of customer grievances.

Spinal cord injury is a major medical problem worldwide for scientists and clinicians. The failure of axons to regenerate in the adult central nervous system (CNS) has been attributed to a variety of factors including the glial scar, the presence of inhibitory factors and the lack of trophic factor support. Several strategies have been developed to rebuild the injured spinal cord in animals such as adding growth factors, providing bridges of peripheral nerves, olfactory ensheathing cells (OECs) or stem cells transplantation. Reviews these roles of transplantation, the recent discovery of OECs capable of generating central nervous system (CNS) tissues, coupled with success in neurotransplantation strategies, has renewed hope that repair and recovery from CNS trauma is possible. Based on results from several studies using OECs to promote CNS repair, our laboratory tried to recruit the human olfactory stem cells cultured from the human nasal polyp tissue, a common surgical specimen of patient’s nasal polyp in ear-nose-throat department. Several specific markers such as low affinity nerve growth factor receptor, p75NTR; oligodendrocyte marker 4, O4, schwann cell intermediate filament, S100-β, glial fibrillary aidic protein, GFAP were used to characterization after in vitro induced. Then, the human olfactory stem cells were transplanted into the spinal cord of the adult rats with complete spinal cord transection. The locomotor’s function of grafted animals were assessed by BBB score and already recovery to weight supporting; and the axonal regeneration were evaluated found by retrograde neuroanatornical tract tracer-Horseradish Peroxidase (HRP). Immunohistochemistry results prove the human olfactory stem cell survival and the new myelin formation after transplanted eight weeks at the beginning, and we believed the cells directly or indirectly promote the repair of injury. To our knowledge, we reprot for this frontier field that the improvement of hindlimb function after human olfactory stem cells transplantation in adult rats T8 transection injury. This work opens new avenue for the treatment of spinal cord injury with olfactory stem cells in human.

Past research about trust repair mainly explored simply one of the strategies to repair trust in a single study. In addition, few studies examined more than 2 strategies at a time, or interaction between strategies and trust. Since the extant literature has indicated that denial and apology of external attribution are more effective in repairing trust, the present study, therefore, aimed to compare the effects these two factors respectively have on trust repair. The interaction between Leader-subordinate relational identity and them were also examined. The data was collected with a quasi-experimental design and subjects were EMBA students of National Changhua University of Education. There were 132 valid samples in the end. To test the research hypotheses, confirmation factor analysis, correlation analysis, and analysis of covariance were used. The results revealed: (1) individuals would exhibit more trust if nonexistence strategy was adopted; (2) individuals would exhibit more trust if defensive impression management tactics was used; (3) nonexistence strategy was more influential than defensive impression management tactics was in repairing trust; and (4) there was no interaction between trust repair and leader-subordinate relational identity. Finally, based on the results, implications for practice and further research were discussed.

Until recently, developers of Asian metropolitan cities have largely ignored the interconnection between nature and cities. During the early stages of urbanization in Taipei this lack of planning caused many of the current challenges faced by the city. As the movement to build more environmentally sustainable cities gains momentum as we head into the 21st century; so should the desire to upgrade existing cities to these new development aspirations. Sadly however, most of the attention primarily focuses on future cities. This thesis, on the other hand, focuses on the eco-regeneration of older cities, namely, Taipei. The strategy to regenerate the city using eco-puncture is due to the fact that repairing key locations will have the most positive impact. To achieve this endeavor the goals of this thesis are twofold; firstly to investigate Taipei ecosystem to gain a comprehensive understanding of its current and future developmental challenges. Lastly to form an eco-regeneration plan using eco-puncture methods, as acupuncture is the preferred method used in Chinese culture in the process of repairing.

In this study, an optimization model is developed to investigate the optimal burn-in time, warranty length and age reduction factor of a product from a manufacturer’s perspective, so that the mean of total product servicing cost is minimized. It is assumed that when the product fails, we conduct minimal repair during burn-in time. The products after burn-in are sold to the market, it is difficult for consumers to judge quality. Therefore, the warranty often plays an important role. If the product during warranty fails before bathtub curve first change point, then we conduct minimal repair. If the product fails after bathtub curve first change point, then we conduct imperfect repair. In this study, a virtual age model is used to express the status after imperfect repair. The degree of imperfect repair will generate different age reduction factors, and bring different age reduction factors into the failure rate. Out-of-warranty, if the product fails before its useful life limits, it causes customer dissatisfaction and incurs a penalty cost for the manufacturer. And Monte Carlo simulations were used to simulate the time-to-failures at different age-reducing factor failure rates to calculate the average number of failures after burn-in, warranty, and post-warranty throughout the product life cycle. We provide a numerical example to determine the optimal burn-in time, optimal warranty length, and optimal imperfect repair degree to minimize total cost. A sensitivity analysis is conducted to evaluate the effect of model parameters on the optimal solution.

Air transport industry is significantly influenced by the economic performance. Since 21st century started, every airlines has been facing most of challenges in years. Especially with Crude oil prices continued to raise, it shows significant downturn in revenue income. Worse to came was late 2008; the “Financial crisis” has distinctly influenced people’s inclination to consuming. This has caused both air travelers and cargo businesses decreased. This financial crisis has caused tremendous Global economic recession, and the case study shows that the studied company also met critical challenges since established. By facing this situation, the company’s coping strategies are: increasing profit and reducing unnecessary cost. This can act two ways, firstly increasing income from customers’ aircraft: secondly using self-maintaining and out-sourcing in order to reduce the cost for company aircraft. Airplanes maintenance service is a long-term investment for the company, and it is crucial to efficiently control the cost at this stage. However, the most important in time is to increase maintenance performance. This study will focus on airplanes maintenance industry and organization of the company and it will analyze internal and external changes. Research unveils those issues will become company threat: -Industrial: Government has not completed the research in advance, thus it caused civil aviation maintenance and repair stations not been able to play the advantages of strategic alliance. -Study Company: maintenance organizations have frequent changes, with relevant accountabilities and responsibilities not clear. -Maintenance and repair station: Aircraft maintenance strategy was complicated. The information systems was not either intergraded accordingly. Plus, there are not enough trained and knowledgeable sales people to perform. Aircraft maintenance industry not merely as civil aviation itself, maintains its associated upstream and downstream industries to development of high-tech industrial base. However, characteristically it requires large funds and a very long-term investment period, but obviously lacks for the will of private investors. Government should be more aggressive to create the environment in order to help Taiwan become the Asia-Pacific regional operations center, APROC, in near future.

Rubenis, Niklavs Andris. "The Ethics of Making: Design for Reuse and Repair : Developing an alternative strategy for studio-based craft and design in a world full of stuff." Phd thesis, 2018. http://hdl.handle.net/1885/164029.
Abstract:
We exist at an interesting point in time. Waste is exponentially
increasing; resources are diminishing; yet we are accumulating
more and more possessions. The world is inundated with stuff; it
is everywhere—in our houses, our offices, on our streets and
littering our environments. Stuff has become a problem.
This is a conundrum for studio-based craft and design (SBCD),
the lens of this project, which, like many design endeavours, has
a preoccupation with the design and the making of products. This
reality raises challenges around roles, responsibilities and
ethical imperatives that drive SBCD in the 21st Century. If it is
acknowledged that design (action) and craft (making) is
responsible for authoring the construction, altering and
interaction of our built environment, then perhaps both are
powerful tools in how we shape our physical existence on this
planet.
SBCD, however, appears to be in crisis often marginalised as a
vocation taught and practiced bound to past models that fail to
sufficiently make links with salient issues of our time. As such,
over the last several years many educational programs that have
supported SBCD across Australia have been discontinued or
amalgamated into larger homogenous programs; the last decade or
so has also seen a swag of cultural organisations move to drop
“craft” from their titles; and there appears to be a decline
of professional craftspeople. , , This presents as another
conundrum and raises the question of the value and relevancy
around SBCD’s offering to a rapidly changing and increasingly
complex world.
Yet SBCD has many worthy inherent attributes. It is a localised
practice that supports a local ecology that further promotes
high-level technical, material and creative skills. Because SBCD
also focuses on an individual in a studio free from industrial
constraints or imperatives, this gives a practitioner critical
agency. But for SBCD to make a relevant and timely contribution
to a world drowning in things will require a decoupling from
existing modes of practice and a deeper understanding of design
and its impact to social, cultural, political, economic,
emotional, environmental, historical, ethical and technological
imperatives—an exploration beyond lingering Modernist ideals of
design as an aesthetic ‘form-giving’ pursuit.
This is the motivation for this practice-led-research: To
interrogate the ‘whys’ and ‘hows’ of practice and to seek
and develop an alternate strategy for SBCD that squarely faces a
question that essentially unravels the very core of what it
does—why make more stuff? Through exploring a broader
perspective of design and by focusing on universal issues that
transcend any one discipline, this research considers that SBCD
turn attention to dealing with that which already exists. This
manifests with a focus on creative challenges and opportunities
for design’s engagement with reuse and repair. Effectively, I
use SBCD as an exploratory tool for inquiry into a) environmental
concerns of waste and these links to design; b) as a strategy for
giving alternative values to goods that have been discarded; c)
and as a practice that engages with social, cultural and ethical
concerns when presented with issues outside of domestic
disciplinary concerns.
Initially revolving around the sub-genre of furniture and
objects, the practice that is presented here transforms into a
much wider scope of what could define a model of SBCD within an
Australian context. Through performing ‘micro-interventions’
into globalised flows of transient materiality, this research
develops a case for SBCD. When recomposed within an ecology of
practice, and by redirecting offerings that engage with issues
beyond an object, SBCD has a relevant and worthy contribution to
make to both the sustainment of the built environment and to
material culture.
This project is the beginnings of an alternative mode of
practice.

The global logistics management includes forward and reverse logistics. The businesses focused the integration of sourcing, making, and delivery in supply chain, and requested quick respondent time and low cost-down for forward logistics. Because the development of environmental consciousness and the regulation of various law in green supply chain, the enterprises have to reconsider reverse logistics in operation and respect the veiled value of reverse logistics in global logistics management. It is for catching the rapid transition of circumstances and keeping the strength of competition. The activities of reverse logistics include return, recycle, reuse, repair, and remanufacturing. For enforcing business competitiveness, it is more important to improve the return and repair process for the reparable product. Otherwise, the raise of consumer requirement and the severe competition between enterprises, it must shorten the repair time and increase the service quality. But it also needs to consider the operation cost at same time. The repair strategies and inventory policies are the influencing variables for balancing operation cost and service quility. In the past, the commerce and maintenance were divided into two processes for IT products. But it combines commerce with maintenance and repair for extending service satisfaction. The international enterprises have to face more strict challenges for taking responsibility to exchange or repair products. It costs a certain extent to hold high customer satisfaction. This study will measure the return and repair metrics in system cost and service level for repair strategy and inventory policy in global repair center.
