Styrning av artikelplacering i lager
This thesis deals with the field of warehouse management, focusing on frequency control of stock. The purpose of the thesis is to reduce the warehouse staff mileage by placing an article based on its number of picks, i.e. how frequently it gets picked. In order to achieve relevant results the following four questions have been answered in the thesis:
- How should the articles be placed with regard to the picking frequency?
- Which factors, if any, needs to be addressed beyond the picking frequency when articles are placed based on frequency?
- Can the present picking system be improved?
- Is frequency placement with regard to the picking frequency profitable to implement for the company?
The thesis is based on literature studies and on the data that has been collected from the company’s business system. Other information has been collected through interviews and observations.
The authors have reached a conclusion that is based on a classification and grading of the company’s articles. An analysis of how the articles where placed at the time of the study resulted in that deficiencies with the current article placement could be identified. The main deficiency was the articles placement with regard to how frequently they were picked. To find out which articles were the most frequently picked an ABC-analysis were done on the company’s standard articles. This thesis is based on the articles that were classified as A-articles in this ABC-analysis.
Articles that were identified among the most frequent was scattered throughout the warehouse, sometimes far away from the stock workers baseline. A number of different needs and criteria could be identified and used to formulate a improvement proposal. This proposal contains exact placements for the articles with the highest frequency as well as zones where the higher frequency articles should be placed. In conjunction with this proposal an additional proposal concerning the company’s picking system was presented. This proposal was based on opinions collected from interviews and on the article placement in the stock. The most influential criteria regarding the picking system was the size of the articles, since the picker needs to place larger articles in the bottom and smaller ones on the top of his pallet.
