Abstract [en]

This thesis deals with control of stock in an inventory, focusing on inventory placement. The purpose of this thesis is to reduce the transport distance within the main stock house while gathering inventory. This will be achieved by reconstructing the inventory placement in consideration with how frequently the inventories get picked and mass of the inventory. In particular, the literature and the data that is collected from the company´s business system have laid the foundation for the thesis. In general, interviews and observations also contributed to the data collection. To fulfill the aim and to produce arbitrary results, two issues have been developed regarding which attributes that should determine the position of the inventory in the stock house and how to obtain a more effective inventory structure? The authors have jointly produced a result of suggestions for future inventory placement in terms of picking frequency and weight. Initially a situation analysis was conducted to identify known problems with the inventory´s placement and storage systems. The problems that were identified were that the inventory placement has no consideration regarding picking frequency. To determine the most frequent picked inventory an ABC analysis was conducted. All of the inventories were spread out throughout the whole stock house. To take in account, the additional criterion, which was weight, a multi-criteria analysis was performed in combination with the ABC analysis. The results of the combined analysis provided that the basis for drawing up concepts for future inventory placement. The proposal includes optimized inventory placements in different zones of the most frequently picked inventory with weight as an additional criterion.

Abstract [sv]

Arbetet behandlar området lagerstyrning med inriktning på optimering av artikelplacering. Syftet med arbetet är att minska transportsträckor inom centrallagret, detta genom en omstrukturerad artikelplacering med hänsyn till plockfrekvens och tyngd. I synnerhet har litteratur samt insamlad data från företagets affärssystem lagt grunden för arbetet. I allmänhet har intervjuer och observationer också bidragit till datainsamling. För att uppfylla arbetets syfte och ta fram ett godtyckligt resultat har två frågeställningar tagits fram angående vilka attribut som bör avgöra en artikels position i lagret samt hur en effektivare lagerstruktur kan erhållas. Författarna har gemensamt arbetat fram ett resultat i form av ett förslag för framtida artikelplacering sett till plockfrekvens och tyngd. Inledningsvis genomfördes en nulägesanalys för att identifiera kända problem med artikelplacering och lagersystem. De problem som identifierades var att artikelplaceringen sker utan underlag för plockfrekvens. För att utröna de mest frekventa artiklarna genomfördes en ABC-analys. Samtliga artiklar lokaliserades utspridda över hela lagret. För att ta hänsyn till ytterligare ett kriterium, vilket var tyngd, genomfördes multikriterieanalys i kombination med ABC-analys. Resultatet av den kombinerade analysen gav underlag för att ta fram förslag för framtida artikelplacering. Förslaget innehåller optimerade artikelplaceringar inom olika zoner för de mest plockfrekventa artiklarna med tyngd som ytterligare kriterium.
