Sourcingstrategier för komplexa produkter och system / Sourcing strategies of complex products and systems

Fehrlund, Christian, Vujdinovic, Daniel January 2011 (has links)
Denna uppsats behandlar hur sourcingprocessen av komplexa system på Försvarets Materielverks (FMV) kan struktureras genom att undersöka parametrar som är viktiga att beakta vid outsourcing. En del av FMV:s strategi grundar sig i att minska den interna verksamheten och att lägga större åtaganden på leverantörer av systemlösningar, för att på så sätt kunna minska behovet av interna resurser. Därför blir det viktigt att besvara huruvida systemansvar bör tas av FMV eller av en leverantör. Rapporten behandlar processen om att fatta ett beslut om make-or-buy och när och varför det är motiverat att överlåta systemansvar till leverantörer. McIvors modell om outsourcing används för att besvara frågan hur FMV bör fatta ett beslut rörande make-or-buy genom att modellen tillämpas på tre pågående projekt. Därefter används "the strategic supply wheel" för att bedöma vilka parametrar som är viktiga att uppfylla både internt och externt vid outsourcing av aktiviteter beroende på om tid, kostnad eller kvalitet är prioriterat i respektive projekt. Inköpsmodellen som används består av fem områden som berör en inköpsorganisation strategiskt. Analysen av den teoretiska modellen görs utifrån ett perspektiv av komplexa produkter och system, då gällande teorier kring handelsvaror inte alltid kan relateras till krigsmateriel, utan kräver någon form av modifiering. Det visar sig i analysen att två av modellens fem områden; organisationsstruktur samt kunskap och kompetens, inte har lika stor påverkan på beslutet rörande make-or-buy. Inom ramen för komplexa produkter och system visar det sig att strategiskt inköp utgår från att dessa två områden är anpassade efter sin industri. Det visar sig att delar av "the strategic supply wheel" inte direkt kan tillämpas på försvarsindustrin då denna skiljer sig stort från kontinuerliga inköp av mindre komplex materiel. II Analysen visar att FMV i så stor mån som möjligt bör överlåta systemansvar till industrin, så länge marknadsrisken rörande antalet leverantörer är låg. Beroende på hur de enskilda projektens prioriteringar mellan anskaffningstid och kostnader skiljer sig åt kommer olika parametrar att behöva beaktas vid outsourcing av systemansvar. Det visar sig att "the strategic supply wheel" måste anpassas för att kunna användas på ett statligt verk som utför anskaffningar på komplexa produkter och system, där beställningarna sker oregelbundet och inte kontinuerligt. Slutligen kompletteras McIvors outsourcingmodell med "the strategic supply wheel". Denna modell ger en strukturerad metod till hur sourcingprocessen av komplexa produkter och system kan genomföras på FMV. / This thesis deals with how the sourcing process of complex systems in the Swedish Defence Materiel Administration (FMV) can be structured by examining the parameters that are important to consider when outsourcing a process. FMV's strategies are based on reducing internal operations and to place greater obligations on providers of system solutions to thereby reduce the need for internal resources. Therefore an important question to answer is whether FMV or a single supplier should take the role of a systems integrator. The report deals with the process of making a make-or-buy decision and when and why it is justified to assign responsibility for systems to a single supplier. McIvors model for outsourcing is used to answer the question of how FMV can make the decision regarding make-or-buy by applying the model to three current projects. The strategic supply wheel is then used to determine which parameters are important to satisfy both internally and externally when processes are outsourced, depending on the priorities of the project. The strategic supply wheel which is used to determine these parameters consists of five areas of interest to a strategic sourcing organization. The analysis of the theoretical model is made from the perspective of complex products and systems, but current theories of consumer goods can not always be related to military equipment without requiring some sort of modification. It turns out in the analysis that two of the model's five areas, organizational structure and knowledge and competence, have less of an impact on the make-or-buy decision. In the context of complex products and systems, it appears that strategic sourcing assumes that these two areas are tailored to their industry. It turns out that some parts of the strategic supply wheel can not be directly applied to the defence industry which differs greatly from the continuous purchasing of less complex materials. III The analysis shows that FMV to the greatest extent possible, should try to transfer system responsibility to the industry, as long as the market risk relating to the number of suppliers are low. Depending on how the individual projects' priorities between acquisition time and costs differs, different parameters have to be considered when outsourcing the role of systems integrator. It turns out that the strategic supply wheel has to be adapted for use at a state institution that acquires complex products and systems, and where orders are done intermittently and not continuously. Finally, McIvors outsourcing model is combined with the analysis of the strategic supply wheel to provide a structured approach to the sourcing process of complex products and systems that can be implemented at FMV.

Textiles from Ethiopia : Applying the market system approach M4P for sustainable Swedish sourcing

Renkel, Ester January 2019 (has links)
This study assesses the applicability of the Making Markets Work for the Poor approach, as described by Sida, to meet sustainability challenges in the textiles- and clothing industry in Ethiopia. While Sweden has been ranked one of the most sustainable countries in the world, exported emissions and impacts have stained this reputation. As Swedish corporations look to Ethiopia as a new potential sourcing market for textile and clothing products, this interview study uses systems- and scenario analysis to assess the applicability of the market system approach Making Markets Work for the Poor, M4P, to answer to the sustainability challenges in the market system of the textile industry in Ethiopia. The results reveal that while sustainability challenges are numerous in regards to economy, environment and society, governance is the central leverage point when addressing systemic change for sustainability. The study concludes that while M4P can address specific sustainability challenges within the system, such as market access for poor and workers’ health issues, the approach does not answer to the fundamental systemic problems. Instead, it builds on a focus on GDP growth, which this study shows to be part of the problem of neglecting environmental and social aspects.

Common Goods & Ephemeral Beauty : An exercise in alternative use, recontextualized materials presented as part of furniture to show the beauty in the common.

Sander, Anton January 2023 (has links)
I’m setting out to find beauty in the universal and common. In the used and unwanted. Giving primary value to these components, materials and techniques that are perhaps not usually considered primary or wanted in an interior context. To challenge our conception of what a beautiful piece of furniture can be. This exercise will be presented as nine chairs. Each chair has its own story, about the site and the material. We do not know what the materials of tomorrow will be. But by looking back at our predecessors we can learn a lot. They were not hindered by scarcities, they used what they had and, in my opinion, created beautiful objects that was durable enough to still be around today. Moving forward we will have to be open, and not afraid of change. It is inevitable, let’s embrace the circumstances as they come and make the best out of it then. Beauty will not be lost because we might need to use other materials. Looking back at these pre-industrial pieces, inspired by this ingenuity and creativity comes a new strain of evolution, or perhaps rather mutation. Artifacts that evoke reflection upon preferences, conventional production, the value of objects and beauty.

Petrographic and Chemical Analysis of Grinding Stones Collected by the Shkodra Archaeological Project

Gjyshja, Zhaneta 10 August 2018 (has links)
The Shkodra Archaeological Project (PASH) took place in northern Albania, particularly in the Shkodra region. PASH focused on analyzing human settlements and social behaviors, from prehistory to modern times. This thesis focuses on the study of grinding stones collected by this project during excavation and survey. This study incorporates macroscopic, petrographic and chemical analyses to source these grinding stones and compares them with sourced samples collected in South Albania to answer questions about raw material selection and social interactions. It was found that, based on their chemical and petrographic properties, grinding stones collected by PASH are different from those collected in southern Albania. Evidence obtained by chemical and petrographic analysis strongly suggests that samples from PASH are likely made of local material. Hence, it was concluded that inhabitants of the Shkodra region were self-sufficient in grinding stone production and did not need to import them from elsewhere.

Uber or Heetch: A comparative study on desirability and usability between ride-sourcing applications / Uber eller Heetch: En jämförande studie av önskvärda aspekter och användbarhet mellan samåknings applikationer

Heikinaho, Alexander, Villarin, Fredilyn January 2018 (has links)
Ride-sourcing is a digital transportation service that has seen a considerable growth in the last half decade especially in the biggest cities around the world. More and more digital platforms for ride-sourcing has emerged since its inception. This study compares the two ride-sourcing applications available in Stockholm— Uber and Heetch, using a combined method of measuring desirability and usability to analyze which factors influence a user’s choice of app. The results showed Uber to have better desirability and usability, and 14 out of the 16 participants chose Uber as their preferred ride-sourcing app. / Samåkningstjänster är en digital transporttjänst som har haft en betydande tillväxt under det senaste halvdecenniet och allt fler digitala plattformar för samåkningstjänster har tillkommit sedan dess uppkomst, särskilt i de största städerna runt om i världen. Denna studie jämför två samåkningstjänster tillgängliga i Stockholm: Uber och Heetch, med en kombinerad metod genom att undersöka önskvärda aspekter och användbarhet för analys av användarnas val av applikation. Resultatet visade att Uber hade bättre önskvärda aspekter och användbarhet, och 14 av 16 deltagande valde Uber som sin föredragna applikation

Evaluating fine-grained events foran Event Sourcing proof-of-concept

Nguyen, Henrik January 2019 (has links)
Data conversion for evolving events in an Event Sourcing System is a complex issue and needs to be maintainable. There are suggested ways handling data conversion today which combine different methods into a framework. However, there is a lack of exploration of different and alternative methods to handle the complicated matter.This thesis explores data conversion with fine-grained events. The purpose is to explore methods and broaden knowledge for handling data conversion while using attribute driven events called fine-grained events. The goal was to build a proof-of-concept that preserves the attributes reliability and availability and can handle data conversion of these specific events.The results found by using fine-grained events are a decrease in terms of system complexity and a proof-of-concept that maintains the desired attributes. / Datakonvertering för utvecklande händelser i ett Event Sourcing System är en komplex fråga som kräver att systemet är enkelt underhållning. Det finns förslag på sätt att hantera datakonvertering idag, vilket kombinerar olika metoder i ett ramverk. Det finns emellertid en brist på undersökning av olika och alternativa metoder för att hantera den komplexa orsaken.Denna avhandling undersöker datakonvertering med finkorniga händelser. Syftet är att utforska metoder och utvidga kunskap för hantering av datakonvertering genom att använda attributdrivna händelser som kallas finkorniga händelser. Målet var att bygga ett proof-of-concept som bevarar egenskaperpålitlighet och tillgängligt och som dessa specifika händelser.även hanterar datakonvertering förResultaten som hittas genom att använda finkorniga händelser är en minskning av systemkomplexiteten och ett bevis på koncept som upprätthåller de önskade egenskaperna.

Design and assembly of differential bevel gears : consequences of in sourcing / Design och montering av koniska växlar i differentialer

Berggren, Adrian, Landgren, Jonathan January 2022 (has links)
The electrification of the automotive industry is the largest change in decades of the industry. This fact demands that established actors evaluate their current strategies and develop new competence. The engineering differences between conventional internal combustion engines vehicles and electric vehicles are many and significant. This means that strategies that made sense in past, needs to be reevaluated and recontextualized for today- and future needs. The goal of this case study was to create a basis from a ‘’birds eye view’’ of sourcing decisions for manufacturing companies. This case is designed based on Volvo Cars wishes and thoughts regarding the decision of in-house design and assembly of differential bevel gears. We believe that other manufacturing companies can use this report as a basis when faced with a similar sourcing decision. The basis of the case is qualitative, to get a thorough quantitative result, deeper investigation into engineering valus, economic impact and company-specific factors must be investigated. The study has been conducted in two parts, where the first part gives an understanding of the technical parameters to understand the process of the process of design and assembly of differential bevel gears. The second part examines, with the help of a business case, earlier case studies and compares the case company's situation and contextualize the wants and needs with a resource-based view and summarized through a SWOT-analysis to finally get a quantification with the help of a concept-decision matrix. Based on what the company's wishes were regarding a sourcing decision, a result could be determined in the form of a recommendation to the company. The results showed that insourcing would benefit the company. This is partly due to the fact that they would get cross-functional knowledge and that a collaboration between design and assembly would benefit the final product, the end-customer and therefore the company at large. The results from the concept matrix indicate that the company should choose the insourcing strategy. But there are many parameters to consider. What is not addressed in this report are the economic impact compared to the technical and organizational gains of an insourcing decision, which could be researched in future studies. / Elektrifieringen av fordonsindustrin är den största förändringen på decennier för bilindustrin. Detta kräver att etablerade aktörer utvärderar sina nuvarande strategier och utvecklar ny kompetens, eftersom de tekniska skillnaderna mellan konventionella förbränningsmotorer och elfordon är många och betydande. Detta innebär att strategier som var lämpliga i det förflutna måste omvärderas och omkontextualiseras för dagens och framtida behov. Målet med denna fallstudie var att skapa ett underlag för inköpsbeslut för tillverkande företag. Detta är utformat utifrån Volvos önskemål och tankar kring beslutet att insourcing precisionssmidda koniska växlar. Vi tror att andra tillverkningsföretag kan använda denna rapport som grund när de står inför ett liknande inköpsbeslut. För att få ett fullständigt resultat måste djupare undersökning av ekonomi, tekniska möjligheter och företagsspecifika faktorer undersökas. Studien har genomförts i två delar, där den första delen ger en förståelse för de tekniska parametrarna. Den andra delen har granskat tidigare inköpsbeslut som jämförts med det undersökta företagets situation och framtida mål. Utifrån vad bolagets önskemål var gällande ett inköpsbeslut kunde ett resultat fastställas i form av en rekommendation till företaget. Resultaten visade att insourcing skulle gynna företaget. Detta beror på att de skulle få tvärfunktionell kunskap och att ett samarbete mellan design och montering skulle gynna slutprodukten. Resultaten från konceptmatrisen indikerar att företaget bör välja insourcingstrategi. Men det finns många parametrar att tänka på. Vad som inte tas upp i denna rapport är de ekonomiska aspekterna av ett insourcingbeslut, som kan undersökas i framtida studier.

Obsidian Sourcing Analysis from Chiquiuitan, Guatemala

Fertig, Sutherland X 01 January 2018 (has links)
The intent of this thesis is to analyze obsidian artifacts from Chiquiuitan, Guatemala to see if the samples can be traced to known obsidian sources in the Maya region based on their unique chemical elements. Another aspect of this analysis is to determine the accuracy and validity of the Handheld XRF instrument on small and irregular obsidian samples. Furthermore, sourcing analysis allows researchers to acquire information about trade, exchange, and acquisition patterns of the material and gives researchers indications to prehistoric, social, and economic features.

Facilitating Innovation of a LargeScale Company with External Startups / Underlätta Innovation av Stora Företag med Externa Startups

Hajzeri, Tesi January 2020 (has links)
Along with an increased environmental awareness, companies are encouraged to go through big, internal transformations and look outside of their core businesses. For them to remain competitive, they need to show an urge for external innovation and collaboration with startups. Front end innovation (FEI) plays a crucial role in the success of ideas, yet the process for it is scattered and unorganised. The purpose of this thesis is to provide structure to external FEI and ensure success to further stages such as commercialization. The thesis was conducted at a large, sustainable materials company, by performing a literature study and qualitative interviews. The results were divided in two parts: (1). Identification of tools and success factors within FEI and (2). Construction of a relevant business model at this phase based on previous findings. The discussion of the results has been derived by performing deep analysis of the data and benchmarking it to previous findings. The thesis resulted in concrete suggestions and improvements of FEI management processes. A business model framework applicable for FEI processes is suggested based on recommendations and findings. Concluding, I argue that the result can be considered as a bridge between large scale companies and external startups, as well as between FEI and commercialization, however, it needs to be validated on other environments than the subject company. / Företag utför stora, interna omvandlingar och tittar utanför sina kärnverksamheter på grund av en ökad miljömedvetenhet. För att de ska förbli konkurrenskraftiga måste de utöka sina processer för extern innovation och samarbete med startups. Front end innovation (FEI) spelar en avgörande roll för framgångsrik innovation, men denna process är utspridd och osystematisk. Syftet med projektet är att införa struktur av externa innovationsprocesser och säkerställa framgång för framtida steg såsom kommersialisering.  Projektet genomfördes vid ett stort företag som fokuserar på hållbara material, genom att utföra en litteraturstrudie och kvalitativa intervjuer. Resultatet delas upp i två delar: (1).  Identifiering av verktyg och framgångsfaktorer inom FEI och (2). Konstruktion av en relevant affärsmodell i denna fas baserad på tidigare litteratur. Diskussionen av resultatet består av en djup analys av samlade data och jämförelse av detta med tidigare resultat.  Projektet resulterade i konkreta förslag och förbättringar av innovations processer. En affärsmodells ram föreslås som är tillämpad för FEI baserad på rekommendationer och litteratur. Avslutningsvis hävdar jag att resultatet kan betraktas som en bro mellan storskaliga företag och externa startups, liksom mellan FEI och kommersialisering men den måste valideras genom testing i andra miljöer och företag.
