In response to recent economic downturn and its turmoil impact, semiconductor distributors begin to take on a customer relationship management approaches in hoping to find critical success factors. Additionally, they hope to actively strengthen internal competitiveness so that market advantage can be gained, and therefore leading to a better industry position. therefore, it is very different to establish noticeable product differentiation within this limited environment, as well as maximizing any profit gain. By emphasizing Customer Relationship development, semiconductor distributors can maintain a more long-term relationship and stay competitive. The purpose of this study is therefore listed as follows: 1.To explore the effect of industrial environment on customer relationship and the associating key factors. 2.To explore the attributes of successful business strategy, its critical factors and their effects on successful customer relationship management. 3.To evaluate on financial capability and its influence on the success of Customer Relationship Management. 4.To explore the relationship between supplier relationship management on customer relation and other critical factors. In this study, Analytic Hierarchy Process (AHP) will be used to divide the topic into two levels. First thru the use of general discussion and review on focus group, a structuralized second level, including the associating four dimensions, along with each dimension¡¦s relevance towards the success factors will be drafted. By synchronizing both AHP qualitative and quantitative data, it is then possible to establish an in-depth understanding on Customer Relationship Management in semiconductor distributors. Through this example, it is then possible to understand the critical importance behind these key factors: customization on product capabilities, ability to improve inventory turnover, and lastly, financial control capabilities.

Purpose – The purpose of this master thesis is to explore how an e-tailer selling bulky items can use a multiple criteria ABC analysis to make its purchasing process more effective, while balancing richness and reach, with the performance measurements of profitability, total asset turnover and inventory turnover. The purpose will be accomplished through a single case study on an e-tailer active on the Swedish furniture and home furnishing market. Methodology – This thesis applies a multiple criteria ABC-analysis to a single case study. The approach is semi-deductive as theory is combined with interviews on how to match and adapt theory about inventory control and purchasing with the specific requirements of an e-tailer selling bulky items. Findings – This thesis has resulted in a set of recommendations that aim to make the purchasing process of an e-tailer more effective. That is, capital and inventory space will be better allocated to the e-tailer’s more profitable items. Among other things, this thesis shows how dead articles can be identified and how a purchaser can prioritize more profitable articles over less profitable ones when making procurement decisions. The other recommendations are for the e-tailer to investigate the possibilities of decoupling the supply chain by keeping stock at the suppliers’ premises, to match the supplier reliability with their importance in the supply chain, and lastly to explore possibilities of drop shipment. Further, the main finding is that a comparison between the A-, B-, and C-classes and the reliability of the suppliers, highlights a gap and a possible risk. Put differently, the importance of a specific item for the business should be reflected in the choice of supplier and the multiple criteria ABC analysis is the tool to illustrate the importance. Keywords – E-commerce, E-tailer, richness, reach, transaction cost, ABC analysis, multiple criteria ABC, MCABC, inventory turnover ratio, supplier selection, purchasing Paper type – Masters thesis / Syfte – Syftet med detta examensarbete är att undersöka hur en e-handelsdetaljist som säljer skrymmande artiklar kan använda en flerdimensionell ABC-analys för att göra sin inköpsprocess mer effektiv och balansera richness och reach, med mätetal som lönsamhet, kapitalomsättningshastighet och lageromsättningshastighet. Syftet kommer att uppfyllas genom en fallstudie på en e-handelsdetaljist verksam på den svenska möbel- och heminredningsmarknaden. Metod – Denna fallstudie använder sig av en flerdimensionell ABC-analys. Tillvägagångssättet är semi-deduktivt då intervjuer och teori om hur lagerstyrning och inköp kan matchas och anpassas till ett företags specifika behov. Resultat – Den här uppsatsen har resulterat i en rad åtgärder som syftar till att göra en ehandlares inköpsprocess mer effektiv. På så vis att kapital och lageryta bättre allokeras till ehandlarens lönsamma artiklar. Bland annat visar den här uppsatsen hur döda artiklar kan identifieras och hur inköparen kan prioritera mer lönsamma artiklar över olönsamma vid inköp. De andra åtgärdena handlar om att undersöka möjligheter att frikoppla försörjningskedjan genom att lagra produkter hos leverantören, att matcha leverantörernas pålitlighet och deras betydelse i försörjningskedjan, och slutligen att utforska möjligheter att utöka drop shipment. Det främsta bidraget är att eventuella felprioriteringar och risker blir tydliga genom en jämförelse mellan A-, B- och C-klasserna och leverantörernas pålitlighet. Med andra ord bör den affärsmässiga inverkan som respektive artikel har på e-handlarens resultat avspegla sig i valet av leverantör. En flerdimensionell ABC-analys kan användas för att påvisa respektive artikels affärsmässiga inverkan. Publikationstyp – Examensarbete för utbildning till civilingenjör (masteruppsats).

Most producing companies aim to reduce tied up capital, which is meant to increase inventory turnover. In this study, an EMS (Electronic manufacturing service) -company, a contract manufacturer, will be studied. The company does not own the products themselves, but is a service company that manufactures to customers. The business has a problem that existed for a long period of time, they have a low inventory turnover among their component inventory. The company therefore wants to increase its inventory turnover in order to reduce its tied-up capital. The aim is to develop knowledge about supplier and customer relationships that affect the stock turnover rate in component stocks. In order to make calculations, it is profitable for the company to order materials multiple times for increased inventory turnover or fewer times to keep down the order cost. Case study is based on qualitative data in the form of interviews and observations. A large part of this study is also based on quantitative data from the company's MRP (material requirements planning) system. The literature is based on articles that deals with key concepts such as EOQ (economic order quantity), customer and supplier relationships. The conclusion of this study suggests that the company should use EOQ to reduce overall order cost while reducing the tied-up capital.

Background: Inventory control is a complex challenge that affects various activities on howinventory is controlled and managed. The management of inventory has a major impact on acompany's profitability and needs to be handled in different ways depending on the situationthe company is operating in. In order to improve operational inventory management forcompanies that have customer-unique products, high inventory availability and the desire forincreased inventory turnover rate, different aspects need to be addressed. Different items in acompany's assortment have different properties, and in order to control items in a goodassortment, a differentiation of the control can be developed. Purpose: The purpose of this study is to find a way to improve Alutrade's operationalinventory control and theoretically contribute with an analysis of which classification basescompanies in a similar situation should analyse when a model for differentiated control isdeveloped. The study aims to differentiate different operational models to adapt to differentitem characteristics to achieve an increased inventory turnover rate. Method: This study is treated with a deductive approach and contains both a qualitative andquantitative research method. The empirical data collected during the study consists ofinterviews, observations, focus groups and excel documents from the company's businesssystem Jeeves for calculations. The data is collected through unstructured and semi-structuredinterviews and observations. Results: By analysing Alutrade's situation, various problems could be identified in theircurrent work regarding operational inventory control. To remedy these problems, differentclassification bases for a differentiated control were analysed. This is to develop a model thatcan provide the opportunity to increase the stock turnover rate based on Alutrade'sconditions. A classification of articles is presented and gives the opportunity to applydifferent operational layer certification methods to the 9 different categories. The differentiated control handles, among other things, methods for service level, crew pointsystem, EOQ and gives recommendations for how they should be applied for each category.Through this, Alutrade can work to increase its inventory turnover rate and prioritize itsefforts where they make the most sense. Through the application of relevant classificationbases, a framework for differentiated control can be developed and different operationalinventory control methods can then be adapted for each category and provide an increase inthe inventory turnover rate.

Styrningen av lager har en stor påverkan påföretags lönsamhet och behöver hanteras på olika sätt beroende på i vilken situation företagetbefinner sig i. För att förbättra operativ lagerstyrning för företag som har kundunika artiklar,hög lagertillgänglighet och en önskan om ökad lageromsättningshastighet behöver olikaaspekter beröras. Olika artiklar i företags sortiment har olika egenskaper och för att styraartiklar på ett framgångsrikt sätt kan en differentiering av styrningen utvecklas. Syfte: Syftet med denna studie är hitta ett sätt att förbättra Alutrades operativa lagerstyrningoch teoretiskt bidra med en analys om vilka klassificeringsgrunder, företag i liknandesituation bör analysera när en modell för differentierad styrning tas fram. Studien syftar tillatt differentiera olika operativa modeller för att anpassa till olika artikelegenskaper för attuppnå en ökad lageromsättningshastighet. Metod: Denna studie behandlas med ett deduktivt angreppssätt och innehåller både enkvalitativ och kvantitativ forskningsmetod. Den empiriska datan som inhämtats under studienutgörs av intervjuer, observationer, fokusgrupper och excelunderlag från företagetsaffärssystem Jeeves för beräkningar. Datan är inhämtad genom ostrukturerade ochsemistrukturerade intervjuer och observationer. Resultat: Genom att analysera Alutrades situation kunde olika problem identifieras i derasnuvarande arbete gällande operativ lagerstyrning. För att åtgärda dessa problem analyseradesolika klassificeringsgrunder för en differentierad styrning. Detta för att ta fram en modell somkan ge möjlighet att öka lageromsättningshastigheten utifrån Alutrades förutsättningar. Enklassificering av artiklar presenteras och ger möjlighet att tillämpa olika operativalagerstyrningsmetoder till de nio olika kategorierna. Den differentierade styrningen hanterarbland annat metoder för servicenivå, besättningspunksystem, EOQ och gerrekommendationer för hur de bör tillämpas för respektive kategori. Genom detta kan4Alutrade arbeta för att öka sin lageromsättningshastighet och prioritera sina insatser dit de görmest nytta. Genom en tillämpning av relevanta klassificeringsgrunder kan ett ramverk fördifferentierad styrning utvecklas och olika operativa lagerstyrningsmetoder kan därefteranpassas för respektive kategori och ge en ökning av lageromsättningshastigheten.
