Pratt and Whitney is expecting an increase in demand for new engines and for parts supportive of aftermarket service, maintenance, and repair. To avoid expensive capital investments in additional production capacity, Pratt is taking several approaches to better utilize existing capacity. In a business where historically margins have been high, demand was flat, and in some years decreasing, and staffing had relatively low turnover, conditions were not forcing leaders to focus on identifying ways to eliminate waste or adapt cutting edge manufacturing analytics. With the introduction of new and innovative products, Pratt & Whitney is quickly approaching conditions where demand will outpace capacity. Additionally, demographics of the employee base has started to hit a point where many key and tenured employees have started to and will continue to retire leaving a knowledge gap behind.
To attack this growing problem, Pratt is taking several approaches to win more efficiency and effectiveness out of existing capacity. These include lean initiatives supported by connected and real time manufacturing technologies. Sensors and monitors are primarily used to gather data about machine condition and performance which is fed back to calculate Overall Equipment Effectiveness (OEE), a lean metric used to identify waste in the manufacturing process. The production team in Columbus has done a lot over the past few years to increase production, but as utilization rates increase, they are looking for new ways to expand capacity. The problem faced by management is identifying and reacting to losses as they occur, rather than retroactively, which is caused, in part, by inadequate access to the data.
This problem of reacting timely to losses is exacerbated by attrition of experienced workers who had tribal knowledge of the processes and how to react, whereas newer employees have not developed those reactionary instincts yet. Pratt & Whitney in Columbus has been collecting and storing data from their forge presses for years; accessing and analyzing that data in real time and integrating decision making based off that data has not been a part of their process. Using machine state tags, that is logic based off Programable Logic Controllers (PLCs) to tell users if the machine is in a run state, going through a changeover, or sitting idle, management can view the state of machines anywhere they can access the Pratt network. This data has also been used to calculate production efficiencies by part number by asset by calculating actual cycle times and comparing them to the engineering design time per part.
This is fed as an input to the new scheduling tool developed over the past few months which is meant to capture the intricacies of how different materials perform on different presses and optimize total production time by maximizing tool life among the presses. I have identified key inputs and business analytics processes to evaluate suboptimal efficiencies in the production process. This has affected the manner in which Pratt & Whitney in Columbus conducts business and permeated throughout the management structure to be included in events from daily production meetings all the way up to weekly executive report outs. Initial results show scheduling efficiency would improve output up to 8%, and the data has been utilized to uncover other areas for efficiency gains amounting to a 25% go get by the end of the year.
This research has shown that a data rich environment can present you with a vast array of opportunities if the data can be aggregated and interpreted timely enough to feed the decision-making process of production and if the organization has a culture to embrace it.

Yang, Simei. "Run-Time Management for Energy Efficiency of Cluster-Based Multi/Many Core Systems." Thesis, Nantes, 2020. http://www.theses.fr/2020NANT4004.
Full textCluster-based multi/many-core platforms represent promising solutions to deliver high computing performance and energy efficiency in modern embedded systems. These platforms often support per-cluster Dynamic Voltage/Frequency Scaling (DVFS), allowing different clusters to change their own v/f levels independently. The increasing application complexity and application dynamism on such platforms arise the need for run-time management. This dissertation focuses on the run-time management of applications on clusterbased multi/many-core systems to improve energy efficiency. Towards the run-time management purpose, this dissertation presents different management strategies that estimate the mutual influence between application mapping and cluster v/f configurations to respectively achieve local optimization within a cluster and global optimization in the overall system. The proposed management strategies can achieve near-optimal management solutions with less strategy complexity compared to state-of-theart strategies. ln addition, this dissertation presents a new modelling and simulation approach that allows the evaluation of run-time management strategies in multi/many-core systems to guarantee that system constraints are fully met. The proposed simulation approach is validated using an industrial modelling and simulation framework

Li & Fung works with over 10,000 factories distributed across 50 countries to design, produce, and deliver hard- and soft- goods to over 2,000 apparel and consumer goods customers. An increasingly prevalent focus of the industry, driven both by regulation and consumer preferences, is to measure, benchmark, and reduce the overall environmental impact of the supply chain. Currently the measurement mechanisms in place rely on a traditional two-phase approach involving factory self-reporting and verification via independent audits. The scope of this project is to assess the efficacy of currently available measurement data in order to inform the requirements for real-time collected data. This project will be broken into four phases. First, existing industry data sources will be described and evaluated in order to assess data quality, understand requirements, and provide recommendations for future data collection. Second, the features of the data will be analyzed in order to develop an understanding of the underlining relationships. Third, using a set of selected features from the second phase, a predictive clustering algorithm for factory-level resource efficiency will be developed and used to benchmark factories. Finally, an analysis will be performed to evaluate the requirements of real time data and how real-time data could improve the benchmarking tool and future tools and services.

Full textThis report is divided into 6 chapters. The content of the first chapter focuses on explaining key theoretical concepts, such as international trade, logistics, maritime transport and also the characteristics of a shipping lines’ operations department: its structure, functions and the main agents within its process chain. For research purposes, four lines that currently operate in APM Terminals were taken as reference: ONE, MSC, HLC & HMM. In addition, the topic of time management will be discussed, detailing techniques and models (such as the Eisenhower Matrix) proposed by experts in the areas of efficiency and productivity. In the second chapter we present the main and specific objectives that will be the basis of our research. Within the secondary objectives we seek to identify possible causes of time mismanagement that may affect the area, particularly when its most important task is executed: the process of filling the CAL (Container Announcement List). The third chapter explains the methodology used, detailing the type of study, sampling technique and data collection methods. In this case, a mixed study was chosen. Finally, the research tools’ formats, the results obtained, and the conclusions and recommendations, respectively, are presented in the fourth, fifth and sixth chapters. It is expected that the obtained findings may serve as a basis for further research, or even help shipping lines identify possible deficiencies in their time management policies to increase their productivity.

Full textMagnetresonanstomografi (MRT) kan användas i många kliniska situationer, men de är begränsade av höga kostnader och tidskrävande egenskaper. Störst fokus har tidigare varit på de tekniska aspekterna av MRT och inte lika mycket på processförbättring. Långa väntetider till MRT-undersökningar kan vara orsaken av ineffektiva arbetssätt på avdelningarna, vilket skapar negativa effekter för patienter. En marknadsundersökning av de svenska radiologiavdelningarna som utför MRT-undersökningar resulterade i ett stort spann av väntetider, från ungefär 21 dagar till 130 dagar. Detta indikerar förbättringspotential i deras arbetssätt. För att förbättra arbetssätt måste de analyseras och mätas. En modell för att mäta effektivitet för processtder på MRT-avdelningar skapades i detta projekt med fem olika mätvärden. Dessa mätvärden är antal undersökningar, undersökningstid, tid mellan undersökningar, användningsgrad av maskiner och efterföljande av bokningstid. Potentiella förbättringsstrategier för att minska väntetider länkade till mätvärderna i modellen diskuteras. Undersökningstiden påverkas mest av tekniken och protokollet för undersökningen, men genom att byta till ett förkortat protokoll kan undersökningstiden minskas avsevärt. Detta kan vara särskilt användningsbart vid screeningundersökningar. Tiden mellan undersökningar kan minskas genom att analysera processen mellan undersökningarna och göra ändringar i förberedelser av patient och undersökning samt arkitektuella ändringar för en mer effektivserad genomströmning. Bokningsprocessen har en stor betydelse för effektiviteten, minskning av väntetider och ökad användningsgrad. Det är viktigt att bokningsprocessen är flexibel för att öka effektiviteten. Som resultat av denna rapport är slutsatsen att ett benchmarkning-projekt kan utföras på svenska radiologiavdelningar för att hitta bra arbetssätt.

Full textCan smart metering program and time-of-use (TOU) prices help reduce energy consumption in New York City? Being able to track electricity consumption levels and to modify consumer usage patterns are important for policy makers to efficiently manage the energy markets. Unfortunately, no reliable and up-to-date data have been brought to bear on this question. I study the effects of time-of-use (TOU) prices and smart metering for the residents of Shanghai and I investigate further what can policy makers do in order to adapt and transfer this successful DSM experience from Shanghai to the residential sector in New York City. The primary objective of my study is to characterize the realistic short-term and long-term potential for the smart metering program in New York City given my empirical findings that the smart metering program has had brought great benefits to the residents of Shanghai. People respond to incentives; if electricity is charged at different prices throughout a day, consumers are likely to shift their usage to when it is cheaper. My findings suggest that policy makers should think harder about designing a pricing scheme that can optimize the social plus

Full textThe construction industry in Sweden today is producing new housing far too slow. At the same time older housing and housing areas are in need of renovating. In general this puts high requirements on the building industry and the requirements become elevated on the construction logistics.A lot of regions in Sweden have increased the building speeds in order to finish the goals set in the construction business, especially in the Stockholm region. In a urban area such as Stockholm where there is a high building pace, the logistics is obstructed. In this geographical complexity there are solutions to the building logistics, and the solution is third party logistics.A third party contractor is applied in the project and manages either parts or the whole of the logistics. They coordinates, plan deliveries and optimize the material-flow to the construction site with a number of different services. From the beginning of the year 2000 modern logistics has become more advanced with third party logistics. This modern logistic is nowadays a competitive strategy between different companies in the construction business.Sundbyberg county is one of the densest populated and fastest growing parts of the Stockholm region. In this area almost all type of constructions exists ranging from offices, housing, public transportations, stores, and general services for the community. Project Orgeln 7, where the project originates from, is located in central Sundbyberg.With higher construction in a densed populated area such as Sundbyberg a higher knowledge of third party logistics is required. This is necessary in order to manage construction in a complex working environment. With the right conditions on the construction site third party logistics will make the building logistics more efficient. This will finally lead to both time and money saved which will contribute to a more profitable production. Third party logistics also contributes to a possible improvement of working environment and a decreased chance of material going to waste at the construction site.The purpose with this report is that through interviews, field observations, literary studies and time studies on site, students get a deeper understanding of how third-party logistics affects the economy of a construction project and how production is affected temporally.Part of the conclusion in this report points out that if the knowledge of third party logistics within a construction site is lacking, this will be difficult to apply. If third party logistics gets to advance to fast, and if people who will be working with this, lacks the knowledge there will be imbalance. This imbalance could lead to third party logistics getting less prioritized.

Full textThe thesis investigates through a case study of the home care service how organisation and management by the principles of New Public Management influences the home care staff´s possibilities to awareness rising, to develop, to communicate and to practice their practical knowledge. The study is based on semi-structured interviews with home care personnel of long professional experience who have experienced the organisational chances that begun in beginning of the 1990:s. The aim of the study is to analys whether the model of organization and mangement influences the conditions of the personnels work practise. The analytical tool of the study is a theoretical framework of organizational theories, with the fokus on rationality and efficiency, and the theory of practical knowledge. The findings show that the organizational- and management modell that is displayed through a distinct exemplary of time- and detail-mangement have had a negative influence on the practical knowledge of the sphere of activities. It is so because of the limitations the organizational model put on the home care staffs possibility to act in accordance with their experience acquired practical knowledge. In other words the current organization of the work in the home care service constitutes of contradictory logics by the fact that the aspiration for cost efficiency takes place on the expence of the practical knowledge and the rationality of care.

Full textThe textile industry encompasses a range of product development possibilities, from fibers, yarns, fabrics, textile finishes, to garment manufacturing. Likewise, in recent years there have been production variations in the nation’s textile industry. As part of this thesis work, data from the last five years of the company Textil Cumpi Perú S.A.C. have been used, a specialized enterprise in the development of alternative fabrics for a variety of textile products aimed at the national and international market. The hypothesis of the present thesis suggests that the application of the work study methodology will increase the weaving production process’ productivity, standardizing production processes and allowing the identification and reduction of defects of the fabric rolls in the aforementioned company. The problem identified in this enterprise is the high number of defects (nonconforming product) of the fabric rolls in the weaving process, which has been exceeding the maximum level allowed by the company. The variety of fabric roll defects includes the following: speckles, fabric contamination, yarn wicks and fabric sags. Based on this, an in-depth literature review was performed, which included indexed research studies referring to the work study methodology, use of industrial engineering tools and success stories of the textile industry for improving processes and increase productivity in the weaving process. After conducting the corresponding evaluations, and with the authorization of the company, a pilot plan and simulations with software were developed to validate the real results of the implementation, where it was concluded that, by applying the work study methodology, it was possible to increase productivity by 11%, from the reduction of more than 480 nonconforming fabric rolls in the weaving process and obtaining savings of more than $48,000 (USD) annually. It is expected that this study becomes a reason for research within the textile field and industry.

Full textBackground: Inguinal hernia surgery is one of the most common surgeries within general surgery, with approximately 20 000 surgeries per year in Sweden. There are three places in Östergötland County where inguinal hernias are executed within outpatient surgery; at Aleris Specialistvård in Motala (ASM), Närsjukvården in Finspång (NiF) and at Medicinskt Centrum in Linköping (MCL). There is a theory that private health care providers are more time-efficient than public health care providers. The private health care providers are considered to perform more operations over a given time though no studies has been done on time efficiency. This study was performed to detect if there is a difference in time in the various steps during the surgery between the clinics, what causes these differences and if the patients differ. Methods: The study includes 70 patients distributed on three outpatient surgery clinics; ASM, MCL and NiF. The inguinal hernia operations were divided into shorter steps measured with a digital watch. Furthermore, data were noted about the patients’ age, ASA-score, BMI and who were present in the operating room. Statistical analyses were performed with the Kruskal-Wallis one-way analysis of variance. The software used was SPSS version 22. Results: The study found no significant difference in BMI, ASA-score and age between the health care providers (p > 0,05). However, regarding the time efficiency, there were significant differences between the clinics. Conclusions: The study concludes that there are big differences in time, within the various steps in the inguinal hernia surgeries, between the clinics. The private health care providers were always faster than the public health care provider. Since no earlier studies have been made in this area, it would be interesting to see if there are similar differences in other types of surgeries.

Full textHigher demands are placed on efficiency and optimization of the flow of distribution centers due to the higher amount of products they are handling. To meet this requirement, lead time reduction is required to reduce non-value-adding time and focus on the work environment for a better ergonomics. Another important thing is to satisfy the customer in order to deliver the right quality on the right time. The purpose of the work is to gain an understanding of efficiency opportunities in warehouse management at a distributing company and to develop a working method that reduces lead time and improves the work environment with a focus on ergonomics. The aim of the study is to develop a more efficient way of working to reduce lead time and develop a better work environment, where the focus is on ergonomics. Issues that were developed to achieve the purpose of this case study concern how a distribution company can handle inventory in a more efficient way in the form of reduced lead time and how inventory management can be improved regarding work environment and ergonomic aspects. A value flow analysis was created based on observations and measurements. The value flow analysis showed that two different processes had opportunities for improvement. Tests have been performed to investigate if different improvements could reduce lead time and improve the work environment. The results showed that a new way of working together with a new layout reduced lead time. The conclusion shows that a more efficient and ergonomic way of working benefits the company, the employees, and the customer.

Full textThe main purpose of Wireless Mesh Networks (WMNs) is to provide a communication backbone for a high number of end-users, thus WMNs have to support heavy traffic load. In this thesis, we intend to maximize utilization and achieve fair allocation of the bandwidth resources in WMNs. We consider two WMN environments: WMN using the IEEE 802.11 MAC standard, which is characterized by its cheap devices and widespread deployment, and WMN using directional antennas, which are emerged as an attractive technology to enhance the spatial reusability in wireless networks. For WMM based on IEEE 802.11, we design NICC, a congestion control scheme that recognizes congestion as neighborhood-related problem, and not a link-based one. Indeed, complex interference among neighboring nodes is the main starvation cause in WMNs. Therefore, NICC handles congestion using mutual cooperation within a wireless neighborhood. NICC makes use of some underexploited fields in the IEEE 802.11frame header in order to provide an implicit multi-bit congestion feedback, and thus ensure accurate rate control without generating overhead, making efficient use of bandwidth. For WMN with directional antennas, we design FreeDMAC, a TDMA-based MAC scheme with contention-free scheduling. FreeDMAC guarantees that each node is aware of all ongoing transmissions in its neighborhood, and thus avoids directional-related problems such as deafness, making efficient use of bandwidth. Moreover, FreeDMAC presents a link-slot assignment that provides two levels of fairness: Per-link and per-flow fairness

Full textДиссертационное исследование посвящено анализу существующих и обоснованию новых подходов к формированию системы принятия инвестиционных решений с целью управления научно-техническим прогрессом. В работе раскрыты значения и основные направления управления научно-техническим прогрессом и обоснована роль инвестиционного анализа в этом процессе. Основными направлениями управления НТП можно считать: определение приоритетов разви-тия отдельных элементов национальной экономики (путем разработки комплексных научно-технических программ); усовершенствование системы оценки качества продукции и технического уровня производства; создание постоянно действующей системы прогнозирования развития национальной экономики; усовершенствование системы государственного экономического стимулирования инновационной деятельности с помощью финансовых рычагов (например, налоговых или кредитных льгот); стимулирование развития и финансовая поддержка науки и образования; предоставление промышленному сектору экономики адаптивного характера; усовершенствование системы оценки инвестиционных проектов с учетом НТП и др. Проанализированы те направления управления НТП, которые непосредственно связаны с не-обходимостью учета фактора времени, а именно: прогнозирование и анализ динамики научно-технических показателей, расчет оптимального периода прогнозирования темпов НТП, измерение уровня неопределенности при оценке основных параметров НТП и ошибок при их вычислении, оптимизация научно-технических решений во времени, установление нормативных сроков службы оборудования и нормативных ставок дисконта (в случае необходимости) и т.д. На основе сравнительного анализа методических подходов к оценке инвестиционных проектов, разработанных в условиях разных экономических систем (на примере плановой и рыночной экономик), сделан вывод о невозможности применения ни одного из них без корректировок в условиях экономики Украины. В связи с этим разработана концепция многоуровневой системы принятия инвестиционных решений, которая включает в себя национальный, региональный, отраслевой социально-экономический анализ проектов, оценку их организационно-технической и коммерческой эффективности, приспособлена к изменению схемы финансирования и состава участников проекта и стимулирует осуществление тех проектов, которые способствуют ускорению НТП. Произведен анализ существующих моделей по оценке нормативов дисконтирования на предмет их применимости в условиях Украины, выбрана оптимальная модель, и на основании стати-стической информации сделан расчет норматива дисконтирования для уровней национального и регионального социально-экономического анализа. Обоснована необходимость изменения механизма учета фактора времени в инвестиционном анализе на основании изменения положения расчетного года, применения дифференцированных ставок дисконта по годам и различающихся по величине ставок для дисконтирования денежных поступлений и инвестиционных вложений. Также разработан механизм учета амортизации в инве-стиционном анализе, позволяющий учитывать тип и предполагаемые темпы НТП. Предложены усовершенствованные методические подходы к расчету показателей “чистая те-кущая стоимость” и “индекс рентабельности”, произведена практическая проверка применения нового механизма на базе реальных инвестиционных проектов, которые выбирались независимо от размера требуемых вложений, отрасли, региона Украины, степени государственного участия в финансировании и других факторов. Выявлено существенное снижение интегрального эффекта и индекса рентабельности при переходе от традиционного способа расчета к предлагаемому, что свидетельствует о сужении рамок принятия проектов за счет учета большего количества экзоген-ных факторов, в т.ч. и НТП. Рассмотрены основные направления реформирования и конкретные предложения по совер-шенствованию современного украинского инвестиционного, инновационного и амортизационного законодательства.

Full textTillverkningsindustrin har gjort en omfattande resa under det senaste århundradet när det gäller att öka produktiviteten, medan byggbranschen inte visar i närheten av samma ökning i effektivitet, förbättrad kvalitet eller minskade kostnader. Det finns många potentiella besparingar i form av aktiviteter som förbrukar resurser men som inte skapar något värde för kunden, även kallat slöserier. Slöserier i kombination med osäkerhet och variabilitet i arbetsmomentens varaktighet tvingar projektens ledtider att vara längre än nödvändigt. Syftet med denna studie är att undersöka möjligheten att förkorta byggprojekts ledtider och undersöka hur byggföretag kontinuerligt kan arbeta mot kortare ledtider. Syftet har uppfyllts med hjälp av en tidsstudie utförd på fyra projekt vid en av de ledande projektutvecklarna av bostadshus i Skandinavien. Slöserier och variabilitet i inredningsskedet har kartlagts. Den uppmätta tiden för varje aktivitet är kategoriserad efter; värdeskapande tid (VT), nödvändig men icke-värdeskapande tid (NIVT) och icke-värdeskapande tid (IVT). Resultaten visar att montering består av 48 % VT, 28 % NIVT och 24 % IVT, medan material hantering består av 0 % VT, 75 % NIVT och 25 % IVT. Vidare visar resultaten på stor variabilitet i varaktigheten av aktiviteter mellan projekten. Teori från lean, logistik och schemaläggning kombinerades för att bilda tre olika scenarier som kan användas för att förkorta projektens ledtider. Det första scenariot beskriver hur man kan arbeta med att eliminera slöserier från processen. Det andra beskriver hur man kan minska variabiliteten och därmed kunna minska buffertarna i tidplanen. Det sista scenariot beskriver hur stödprocesser, som t.ex. materialhantering, kan brytas ut från den kritiska linjen, i syfte att minska projektets ledtid. Ettförslag till ett generellt sätt att kontinuerligt arbeta med att minska projektens ledtider är ocksåframtaget och innehåller en kombination av de tre scenarierna. Det framkommer att centrala aspekterför att förkorta projektens ledtider är takttid, variabilitet och risk. Det föreslagna arbetssättetinnefattar en kombination av de tre scenarierna, där hänsyn tagits till deras inverkan på varandra.

Full textIn the management of port terminals, a common problem has been evidenced, high traffic of trucks and long waiting times given the variability of trucks arrival. This is a significant challenge for ports. This situation has given the opportunity to investigate in this matter and make use of a Truck Appointment System (TAS) together with other tools corresponding to industrial engineering for the optimization of truck service processes within a port terminal in Peru. To do this, a diagnosis is made of the company object of study and through a simulation of discrete systems, the technical viability of the proposal is validated. It was demonstrated that a procedure of attention based on appointments, Last in, First Out (LIFO) management for containers and development of visual management within the container yard; it is a highly viable option to shorten waiting times and unproductive movements of containers.

Full textThe theme of this thesis within the field of training throughout the working lives of administrative officers of the state of Djibouti and in particular the use of ICT.Indeed, the role of ICT in adult education, has become an important means to modernize teaching and mode of transmission of knowledge to wider audiences. There has been a very important phenomenon of convergence and distance learning worldwide. Many of the National School of Administration (ENA), including those of industrialized countries now devote human and financial resources very important to teach digital. They use this system to enrich their classroom teaching and sometimes also to provide programs remotely.It is therefore to study the environment of this system in its complexity, taking into account its specifications (educational and functional), but also its dynamics, its implementation and operation. We will consider in particular the educational and technological dimensions of alternative teaching methods and training of adults in order to propose and to adapt to the context of Djibouti.Thus, it is to find clues and criteria for strategic decision making to enhance the skills of human resources of the government of Djibouti

Full textThe last twenty years saw the emergence of wireless systems in everyday’s life. They made possible technologies such as mobile phones, WiFi or mobile Internet which are now taken for granted in today’s society. The environmental impact of Information and Communications Technology (ICT) has been raising exponentially to equate the impact of the airline industry. The green computing initiative has been created in response to this observation in order to meet the 15%-30% reduction in green-house gases by 2020 compared to estimations made in 2002 to keep the global temperature increasebelow 2°C. In this thesis, we studied power-saving techniques in wireless networks and how they interact with each others to provide a holistic view of green networking. We also take into account the radio frequency resource which is the most commonly usedcommunication medium for wireless systems and is becoming a scarce resource due to our society’s ever-increasing need for mobile bandwidth. This thesis goes down the network stacks before going up the hardware and software stack. Contributions have been madeat most layers in order to propose an autonomic wireless network where nodes can work collaboratively to improve the network’s performance, globally reduce the radio frequency spectrum usage while also increasing their battery life

Full textFör att vara konkurrenskraftig i dagens företagsklimat måste företag ständigt förbättras och bli effektivare. Detta kan uppnås bland annat genom att utveckla och effektivisera ett företags värdekedja. Bombardier Rail Control Soutions (RCS) har växt framförallt genom företagsförvärv, dock har förvärven inte integrerats på ett bra sätt in i den existerande värdekedjan. Detta har resulterat i en decentraliserad värdekedja där RCS:s olika arbetsplatser använder olika ERP system. Konsekvensen av detta har lett till en ökande manuell arbetsbelastning, brist på synlighet mellan siter och en ineffektiv värdekedja. Målsättningen med det här projektet har varit att identifiera hur Bombardier RCS kan utveckla och effektivisera sin värdekedja genom att centralisera olika delar av den, exempelvis ERP system och olika processer. För att uppnå detta har ett nära samarbete med Bombardier genom projektet varit centralt med intervjuer, möten och diskussioner, tillsammans med en litteraturstudie. Dessutom har presentationer framförts kontinuerligt för att säkerställa att resultaten följt Bombardier RCS:s mål. RCS:s historiska data har också analyserats. Utifrån ovannämnda metoder har flera problem löst och förbättringsområden har identifierats. Problem som har lösts är bland annat att centralisera RCS:s masterdata och hur man kan centralisera processer hos Bombardier RCS. Förbättringsområden är bland annat fördelarna med att centralisera Bombardier RCS:s värdekedja och vinsterna med ett centrallager. Bombardier RCS bör även centralisera deras ERP-system för att möjliggöra globala MRP-beräkningar och så vidare. Vidare har det identifierats att det finns en förbättringspotential för Bombardier RCS:s leveransprecision som kan lösas dels med att integrera värdekedjan (med leverantörer) eller/och lagerlägga artiklar. Slutsatsen är att Bombardier RCS bör centralisera sin värdekedja stegvis eftersom det är omöjligt att centralisera allt på en gång. Genom en centraliserad värdekedja kan det minimera den manuella arbetsbelastningen, skapa visibilitet mellan olika arbetsplatser, bidra till en bättre leveransprecision och effektivisera värdekedjan. Genom att göra detta kommer Bombardier RCS bli mer konkurrenskraftig, vilket kommer bidra till en fortsatt stark marknadsposition i branschen.

Full textIn the last 20 years, I have been conducting various research projects focused on the management of risks and uncertainties in the petroleum exploration domain. The various research projects detailed in this thesis are dealing with problematics located throughout the whole Exploration and Production chain, from seismic acquisition and processing, until the optimal exploration to development wells placement. Focus is made on geophysical risks and uncertainties, where these problematics are the most pronounced and paradoxically the less worked in the industry. We can subdivide my research projects into tree main axes, which are following the hydrocarbon exploration process, namely: seismic processing, seismic interpretation thanks to the integration with various well informations, and eventually the analysis and extraction of key uncertainties, which will be the basis for the optimal calculation of in place and recoverable volumes, in addition to the associated risk analysis on a given target structure. The various research projects that are detailed in this thesis have been applied successfully on operational North Africa and North Sea projects. After introducing risks and uncertainty notions, we will detail the exploration process and the key links with these issues. I will then present four major research projects with their theoretical aspects and applied case study on an Algerian asset

Full textNuförtiden så har multifunktionella bärbara hälsoenheter fått en betydande roll. Dessa enheter drivs vanligtvis av batterier och är därför begränsade av batteritiden (från ett par timmar till ett par veckor beroende på tillämpningen). På senaste tiden har det framkommit att dessa enheter som används vid en fast spänning och frekvens kan användas vid flera spänningar och frekvenser. Genom att byta till lägre spänning och frekvens på grund av effektbehov så kan enheterna få enorma fördelar när det kommer till energibesparing. Dynamisk skalning av spänning och frekvens-tekniker (såkallad Dynamic Voltage and Frequency Scaling, DVFS) har visat sig vara användbara i detta sammanhang för en effektiv avvägning mellan energi och beteende. Hos Imec så använder sig bärbara enheter av den internt utvecklade MUSEIC v2 (Multi Sensor Integrated circuit version 2.0). Systemet är optimerat för effektiv och korrekt insamling, bearbetning och överföring av data från flera (hälso) sensorer. MUSEIC v2 har begränsad möjlighet att styra spänningen och frekvensen dynamiskt. I detta examensarbete undersöker vi hur traditionella DVFS-tekniker kan appliceras på MUSEIC v2. Experiment utfördes för att ta reda på de optimala effektlägena och för att effektivt kunna styra och även skala upp matningsspänningen och frekvensen. Eftersom att ”overhead” skapades vid växling av spänning och frekvens gjordes också en övergångsanalys. Realtidsoch icke-realtidskalkyler genomfördes baserat på dessa tekniker och resultaten sammanställdes och analyserades. I denna process granskades flera toppmoderna schemaläggningsalgoritmer och skalningstekniker för att hitta en lämplig teknik. Genom att använda vår föreslagna skalningsteknikimplementering har vi uppnått 86,95% effektreduktion i jämförelse med det konventionella sättet att MUSEIC v2-chipets processor arbetar med en fast spänning och frekvens. Tekniker som inkluderar lätt sömn och djupt sömnläge studerades och implementerades, vilket testade systemets förmåga att tillgodose DPM-tekniker (Dynamic Power Management) som kan uppnå ännu större fördelar. En ny metod för att genomföra den djupa sömnmekanismen föreslogs också och enligt erhållna resultat så kan den ge upp till 71,54% lägre energiförbrukning jämfört med det traditionella sättet att implementera djupt sömnläge.
