This paper deals with the problem of cell formation encountered in the early stage of the fundamental design process for the realization of Cellular Manufacturing Systems based on Group Technology. CAFPLAN-I is a human-computer interactive software package which has been developed to solve the cell formation problem. It is particularly useful for such practical situations that alternative machines exist in manufacturing processes. This paper presents the basic concept and the cell formation procedure through the application of CAFPLAN-I to a hypothetical case study.
