| 摘 要： | Accomplishing the objective of a warehouse de-pends on having a goodlayout.This paper deals witha fuzzy adjacent multiple-level warehouselayout prob-lem(FAMWLP)in which many types of items haveto be stored in the cells of a warehouse which hasmore than one level.It is desirable that a number ofitems of the same type can be stored in the same cellunless the inventory requirement exceeds the capacityof a cell.In such case,the item type will occupymore than one cell.We call thisitemtype a spli…

| Abstract: | A warehouse layout problem where the warehouse has more than one level and both the distance from the cell to the receive/exit bay and demand of item types are fuzzy variables is proposed. The problem is to find a layout with the minimum transportation cost subject to adjacency and other constraints. A fuzzy expected value model is given and an ant colony system is designed to solve the problem. Computational results indicate the efficiency and effectiveness of the method. |
