Ökad effektivitet till lägre kostnad : En kostnadseffektivisering av materialflödet på ICA Sverige ABs distributionsenhet i Borlänge

by Asplund, Sofie; Lindholm, Ida

This study concludes the results of a Master thesis with purpose to increase efficiency and reduce the total cost at ICA Sverige ABs distributions unit in Borlänge, also called DE Borlänge. DE Borlänge is one of five distribution units in Sweden and distribute products to over 300 stores. One of the problems at DE Borlänge is variation in volumes, which lead to difficulty finding an optimal way to run the flow. To get a better picture of how the distribution unit works and where improvements can be found a model was created. The first step in the model was to map the flow of the products. Next, some improvement areas were identified which corresponds to the second step in the model. For further focus, a few of the improvement areas were elected. The third step in the model was to analyze the elected improvement areas. This was carried out by dividing them into different alternatives in order to reduce the total cost and increase the efficiency. The alternatives were: • • • • • Alternative 1 – Initial position Alternative 2 – Move volumes at night Alternative 3 – Move volumes on Saturdays Alternative 4 – Improve the capacity factors Alternative 5 – Increase possible personal assets To look more closely into the alternatives a model was built. The point with the model is to optimize the salary expenses for the storage workers. A couple of conditions were made to make the model trust worthier. These were limits for capacity, breaks and space at the storage. Each alternative were examined with the model which resulted in that the total cost for DE Borlänge may be reduced by moving volumes at nights and on Saturdays. It also resulted in increased efficiency, in terms of number of used working hours. Still, it is worth mentioning that each alternative resulted in reduced total cost for DE Borlänge. Conclusions that have been drawn from the results are the following: • • • DE Borlänge should take advantage of the over-capacity that exists today in form of space and staff. By moving times where the products get available, DE Borlänge can find possibilities to reduce their total cost. DE Borlänge should focus on increasing the efficiency by trying to enable more staff every half hour instead of focus on the performance of individuals in the staff.
