Abstract:   (15739 Views)
The dynamic facility layout problem involves the design of facility layouts in which the flows of materials between activities can change during a multi-period planning horizon. In the static layout problem, it is assumed that all the activities are constant. However, in today’s volatile markets, the business conditions are changing. So the similar changes are imposed on the facility projects and the flows of material between activities. In this paper, a new model of the dynamic facility layout problem is studied that the flows of materials are considered as fuzzy numbers with different membership functions. For modeling the problem, the expected value, the chance programming and the probabilistic programming methods are utilized using fuzzy programming. A new method is proposed for solving the model and a numerical example is given to describe the method.
