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.展开更多

During storage planning, in order to design a reasonable layout of warehouses, companies must consider seasonal product, quantity demand characteristics and the treasury itself highly characteristic and so on. Handling the number of products and their performance, will certainly affect the design of the warehouse place;at the same time, with seasonal variations, warehouse receipt must not only be able to accommodate the capacity of the warehouse area and height for design, but also consider that forklift and artificial operation need some work area, and it cannot affect normal operation of the product by placeholder area.展开更多
