Abstract

The dynamic facility layout problem (DFLP) is the problem of finding positions of departments on the plant floor for a multi-period planning horizon such that departments do not overlap, and the sum of the material handling and rearrangement costs is minimised. In this paper, the departments may have unequal-areas and can be placed anywhere within the boundary of the continuous plant floor. Because of the complexity of the problem, only small-size problems can be solved in reasonable time using exact methods. As a result, a hybrid heuristic, which consists of a dual simplex method and a tabu search (TS) heuristic, is developed for the DFLP, and the heuristic was tested on some instances from the literature. The results obtained demonstrate the effectiveness of the heuristic.
