Effektivisering av lager- och orderhanteringsaktiviteter på Dormakaba AB

Sammanfattning:   The problem Being able to manage the process- and material flows in an efficient way is essential for delivering goods, on time and at the lowest possible cost, to customers. Efficient flows have always been of great importance, but in the past few decades they have received more attention, especially within industrial circuits. The interest in creating efficient flows has increased in line with market developments, its increased complexity and variations. But with the new market companies have come to face new problems. Poor delivery service, high inventory- and handling costs and longer lead times. Longer lead times lead to greater costs for the company. It’s also a competitive disadvantage, which means that the company may end up losing customers to competitors.   With this in mind, the decision was made that this study would focus on reducing the lead times at the company’s warehouse department. The questions on which this study is based are as follows:   Which factors affect the lead times for inventory- and order management? How can you increase the efficiency and shorten the lead times for inventory- and order management?   Case study During this thesis, a case study has been conducted at Dormakaba AB. The case study has been delimited to include only the inventory- and order management at the company. The overall approach for this study has been the DMAIC-method. The gathering of data has been made through observations, interviews and time studies.   During the case study, a lot of unnecessary movements were identified in the process of inventory- and order management. This was mainly due to the layout of the warehouse, the design of the workbenches and the lack of structure. In order to reduce the lead times, the unnecessary movements needed to be minimized as much as possible. Therefore the improvement proposals are primarily focusing on reducing unnecessary movements.   Results and conclusions During the course of the study a time study, on an order handling process, were done. The order, which could be considered to be of normal size, were completed in 32,8 minutes. By making an ABC-analysis and design the inventory after the results of the analysis, changing workbenches, introducing 5s on the workbenches and delivery area and introducing a new layout, it was estimated that a time saving of 6,8 (20,73%) was possible. This would allow an annual time saving of 2 266,5 hours.
