Model and algorithm for the slab location optimization decision problem based on fuzzy matching

For solving the slab location decision problem with hybrid stowage,a slab location model using a membership function was built to express the level of matching on the related attributes of length,width and thickness between the storing slabs and stored slabs in a warehouse.According to the characteristics of the problem,a hybrid discrete particle swarm algorithm,called DPSO-MC,was proposed based on crossover and mutation in genetic algorithms.Experimental results on a real case of a steel plant demonstrate that the model and algorithm are feasible and effective.
