developed a heuristic for multi-floor facility layout with considering capacity of elevator. Patsiatzis et al (2002), presented a mixed integer linear formulation for multi-floor facility layout problem. This work was extended model of the single floor work of Papageorgiou and Rotstein (1998).
In this paper, we present a new exact model for both static and dynamic multi floor facility layout problem. At first, we propose mixed integer programming (MIP) formulation for static multi floor facility layout problem, and then we extend it to dynamic multi floor facility layout problem.
Remainder of paper is organized as follows: in section II, mathematical model is proposed, in section III, computational results are illustrated and in section IV, conclusions are discussed.
