A study of Vendor Managed Inventory implement in the Military Defence Industries

Lee, Keh-Yeu 22 July 2003 (has links)
Abstract Owing to environment highly competitive, In order to reduce the cost or occupy market, the companies must seek the best new process or model to face this situation. Highly secret of Military Defence Industries is proprietary business in the domestic. The inbound process cannot satisfy requirements of user now. So, many opportunities of demand were lost. In recent years, the Defence budget deflated. How to use this geographic advantage¡H Not only sell the product, but also provide the more and best service. To cerate one position which cannot be replaceable. The research applies business process reengineering. Having two faults in current supply process of Military Defence Industries are¡G(1) It may restrict service to user.(2) It cannot control the conditions of product of using. When implement Integrated Logistics Support project, we cannot find the powerful point to link with user. Through the process reengineering thinking, we don¡¦t change the user organization process. Only change supplier the source of demand and the manufacturing & delivery planning. Apply Vendor Managed Inventory model, explicit objects can reach reducing supply cycle time. Improving the availability ratio of products. Implicit objects can control the conditions of products and real requirements of user. This information will also help to improve the quality of products and avoid put resource in wrong place.

Suitable ILS-processes : How suitable ILS-processes between FMV and their partners can be designed for materiel systems with high-turnover-rates / Anpassade ILS-processer : Hur anpassade ILS-processer mellan FMV och deras medparter kan designas för materielsystem med hög omsättning

Boork, Adam January 2021 (has links)
Swedish military logistics are in large part dependent on civilian business assets in the acquisition of certain materiel. Here are products with high commercial-turnover-rate, which for a military organization who want to be able to buy the same product years later makes it difficult. The Swedish Defence Materiel Administration (FMV) and their consultant partners frequently run into this problem in their support functions, specifically the integrated logistics support (ILS) process. By request of the FMV consultant partner Svekon, the main purpose of the study is to investigate the subject of Swedish logistics and general ILS processes. This with the goal of determining how suitable ILS-processes can be designed for materiel systems with high-turnover-rates. The study is divided into investigations of the ILS subject, the current process within FMV and its partners, and factors around Swedish defence-logistics that play a part in the process. Methods include interviewing personnel who work within two exemplified materiel areas, including FMV, Svekon, civilian contractors, and the users within the Swedish Armed Forces (SwAF). Second is a literature study based on prior works and theories around ILS and Swedish logistics conduct, including models, guidelines, and factors that contribute to an efficient ILS-process. With the gathered material from both methods the major contributing factors and models are discussed and put into highlighting an ILS-framework to follow. The conclusion through a broader understanding of military logistics suggests that the term “logistics” and suitability of “efficiency” are in large part up to interpretation by the different actors, due to different underlying processes and goals. As such, the final contribution is a set of universal success factors that with the example of an applied ILS-framework for Svekon can be used by any ILS actor to construct a process according to their background. / Svensk militärlogistik är till stor del beroende av civila affärstillgångar vid anskaffning av viss materiel. Här finns produkter med hög kommersiell omsättningshastighet, vilket för en militär organisation som vill kunna köpa samma produkter år senare gör det svårt. Försvarets materielverk (FMV) och deras konsultparter upplever detta som ett problem i sina stödfunktioner, så kallat integrerat logistikstöd (ILS). På begäran av FMV:s konsultpart Svekon är huvudsyftet med studien att undersöka ämnet kring svensk logistik och allmänna ILS-processer. Detta med målet att avgöra hur anpassade ILS-processer kan utformas för materielsystem med hög omsättningshastighet. Studien är indelad i utredningar av ILS-ämnet, den nuvarande processen inom FMV och dess partners samt faktorer kring svensk försvarslogistik som påverkar processen. Metoder inkluderar intervjuer på personal som arbetar inom två av dessa materielområden, bland annat FMV, Svekon, civila företag, och brukarna inom Försvarsmakten (FM). Andra metoden är en litteraturstudie baserad på tidigare arbeten och teorier kring ILS och svenskt logistikbeteende, inklusive modeller, riktlinjer och faktorer som bidrar till en effektiv ILS-process. Med det insamlade materialet från båda metoderna diskuteras bidragande faktorer och modeller som sedan kan användas i ett applicerbart ILS-ramverk. Slutsatsen genom en bredare förståelse av militär logistik antyder att begreppen "logistik" och anpassning av "effektivitet" till stor del är upp till tolkning av de olika aktörerna, på grund av individuella bakomliggande processer och mål. Genom detta blir det slutliga bidraget en uppsättning av universella framgångsfaktorer som appliceras i ett tillämpat exempel på ILS-ramverk, baserat på Svekon som användare. Med faktorerna och de presenterade modellerna kan sedan vilken ILS-aktör som helst i processen utforma ett eget ramverk baserat på sin egen bakgrund.

Multi-agent decision support system in avionics : improving maintenance and reliability predictions in an intelligent environment

Haider, Kamal January 2009 (has links)
Safety of the airborne platforms rests heavily on the way they are maintained. This maintenance includes repairs and testing, to reduce platform down time. Maintenance is performed using generic and specific test equipment within the existing maintenance management system (MMS). This thesis reports the work undertaken to improve maintainability and availability of avionics systems using an intelligent decision support system (IDSS). In order to understand the shortcomings of the existing system, the prevalent practices and methodologies are researched. This research thesis reports the development and implementation of an IDSS and the significant improvements made by this IDSS by integrating autonomous and independent information sources by employing a multi-agent system (MAS). Data mining techniques and intelligence agents (IA) are employed to create an expert system. The developed IDSS successfully demonstrates its ability to integrate and collate the available information and convert into valuable knowledge. Using this knowledge, the IDSS is able to generate interpreted alerts, warnings and recommendations thereby reasonably improving platform maintainability and availability. All facets of integrated logistics support (ILS) are considered to create a holistic picture. As the system ages, the IDSS also matures to assist managers and maintainers in making informed decisions about the platform, the unit under test (UUT) and even the environment that supports the platform.

Increasing Availability Through Reduced Delays in Large Systems : A Case Study Based in Systems Engineering, Integrated Support Logistics, and Lean / Förbättrad tillgänglighet genom minskade väntetider i stora system : En fallstudie baserad på systemteknik, integrerat logistikstöd och lean

Nilsson Nordahl, Erik January 2022 (has links)
Increased trends towards servitization within previously exclusively manufacturing industries makes a larger part of maintenance become the responsibility of the manufacturer. This increased responsibility makes it more important for suppliers to know how different parameters contribute to cost, to be able to price their contracts correctly. Systems Engineering (SE) and Integrated Logistics Support (ILS) are two current methodologies on how to manage large systems. These methodologies are mainly used within defence industries and large capital-intensive infrastructure projects but are today also utilised in civilian industries. With the new methodology of Model Based Systems Engineering (MBSE) and the new demands of servitization it becomes more important to know how different parameters affect the final cost of a project during the very early phases of development. Within ILS the parameters Administrative Delay Time (ADT) and Logistics Delay Time (LDT) have previously not received attention proportional to their contribution to overall availability in projects. This thesis is based in literature, interviews of industry professionals, and the study of a real case of an electrical charging infrastructure project currently in development. From these sources multiple paths to resolve the issues with support from ILS, MBSE, SE, and other management literature are explored. Several attributes of the case, and characteristics of MBSE and ILS leads to the conclusion that coupling the methodologies with Lean methods would lead to better insight into where critical points in the explored system are and give ways of resolving issues with ADT and LDT that exist. The combination of MBSE and Lean methods could successfully identify possible critical points in the error handling of the electrical charging infrastructure system early in the process of implementation. Conclusionary the combination of MBSE, ILS, and Lean is a possibly powerful way to identify and improve the availability and consequently the cost of a project in the early stages. / Tjänstefiering är en trend som gör att en allt större del av underhåll inom tidigare endast tillverkande industrier blir tillverkarens ansvar. När detta ansvar ökar blir det viktigare för tillverkaren and veta vilka parametrar som är kostnadsdrivande. Detta för att kunna prissätta sina tjänster korrekt. Systemteknik (SE) och Integrerat Logistikstöd (ILS) är två metodologier som används till att hantera underhåll av stora system. Dessa nyttjas främst inom försvarsindustrin och inom kapitalintensiva infrastrukturprojekt, men används även i privat industri. Med hjälp av en utveckling inom SE, Modellbaserad Systemteknik (MBSE), och med de krav som tjänstefiering innebär så blir vikten av att ha korrekt angivna parametrar tidigt i projektet mer tydlig. Inom ILS är särskilt parametrarna administrativ väntetid (ADT) och logistisk väntetid (LDT) särskilt eftersatta med hänsyn till hur mycket de påverkar tillgängligheten och kostnaderna för systemet. Detta examensarbete baseras på tillgänglig litteratur inom nämnda områden, intervjuer med industrirepresentanter, och dokumentation och intervjuer i ett riktigt fall. Det riktiga fallet är ett pågående projekt för uppbyggnad och underhåll av laddningsinfrastruktur för eldrivna fordon. Från dessa källor utforskades och analyserades flera vägar för hur man skulle kunna förbättra hanteringen av ADT och LDT med grund i litteraturen kring ILS, MBSE, och SE med annan litteratur inom mangament som stöd. Fallets egenskaper, och egenskaper hos ILS och MBSE leder till slutsatsen att en kombination av MBSE och Lean skulle leda till att man lättare kan utforska kritiska delar av ett underhållssystem, och åtgärda existerande problem med ADT och LDT. En kombination av dessa principer kunde identifiera kritiska punkter i felhanteringssystemet hos laddarna i infrastrukturprojektet trots att projektet befann sig tidigt i implementationen. Slutligen kan konstateras att MBSE, ILS och Lean är en möjlig kraftfull kombination för att förbättra tillgängligheten tidigt i ett projekts livscykel.

The development of a framework for an integrated logistics support system within a high technology industry in a developing country

Lambert, Keith Richard 31 March 2008 (has links)
Competitive and high-risk environments require complex high technology systems, which need to be supported and maintained over their respective life cycles. These systems often have a significant consequence of failure, and require complex management systems to achieve their operational objectives. Significant leadership and management challenges exist, not only in South Africa, but also in other developing countries, where systems may be utilised beyond the lifespan they were designed for and are susceptible to obsolescence. This study was conducted by following a structured process; the research consisted of three stages. The first stage dealt with the research problem, including the delimitations of the study. The second stage was further divided into three phases. The first phase deconstructed the appropriate literature, which included the interpretation of numerous definitions of logistics, integrated logistics support, and the integrated logistics support elements. In addition, the research was grounded in the fields of operations management, supply chain management and integrated logistics support. The second phase focused on the deconstruction of six case studies from four different high technology complex systems. From the analysis of the first two phases followed the third phase of research, which focused on the identification of areas requiring further research. Further research was conducted by means of a questionnaire, the results of which were analysed for variable dependency and variable association. The third stage of the research included the collation and analysis of the findings of the first two stages of research. The analysis utilised the principles of Mode 2 research and design science research, whereby an ILS framework and associated grounded technological rules have been recommended. These recommendations are robust in nature, as they can be applied in the most challenging environment and circumstances as identified. Furthermore, by grounding the theory in the disciplines of operations management, supply chain management and integrated logistics support, the reliability, validity, relevance, and applicability of the study could be substantiated. This implied that the generated theoretical knowledge could be transferred to and applied in practice, and as such, an organisation can reap substantial value added benefits, and gain considerable competitive advantage in the market place by applying this developed ILS framework and associated ILS grounded technological rules. / Business Leadership / D.
