| Popis: | 83 The result of facility layout will influence the performance of production system and is the key factor of deciding production cost. This paper presents a multi-objective facility layout model for combining quantitative factor (material handling cost) and qualitative factor (closeness rating). In this model, closeness rating is weighted by a cost parameter in order to reduce the influence of difference between two objective functions, and let the quality of individual objective be close each other. During the programming procedure, consider changes in production level, this is "flexibility" of facility layout. In this paper, we use lost cost to measure the flexibility of a layout. The lower the lost cost is, the more flexible the layout is. Finally, this paper presents a two-phase algorithm to solve the flexible facility layout problem. In phase one, CRAFT is ployed to obtained the suboptimal layout for each period. Using these suboptimal layouts, the lost cost of each period can be caculated. In phase two, the most flexible layout during planning horizon can obtained by using simulated annealing algorithm. |
