Abstract: In this research, a new multi-period strategy is suggested for machine and part family formation process, and compared with two other old common strategies. Single- and multi-period mixed integer mathematical models for simultaneous machine/component grouping and assignment are developed as a tool of comparison. The models consider the trade-offs of cell configuration, machine procurement and salvage, part subcontracting, inter-cell movement, capital investment costs, which reflect the significance of real life planning aspects. The heuristic method of machine cell and part family formations under the criteria of maximum cell similarity and minimum machine number is proposed. This heuristic method is integrated with a mathematical program, which optimizes various cost aspects into a two-stage model. Possible advantages and disadvantages of various multi-period part/machine grouping strategies and their associated costs are investigated by using the developed heuristic method and mathematical programming models. Three- and five-period example problems are illustrated to compare various planning strategies with varying cost values. Behaviour of models with changing cost values are also discussed.
