Abstract: The number of cells is a key factor of Cell Formation(CF) problem.After analysis the defects of currently validity function,a new validity measure and a algorithm which can obtain the optimum number of groups are both proposed,these are based on the Fuzzy C-Means (FCM) algorithm and the feature of CF problem.The new validity measure take into account the number of machines and parts in the cells,the essence of CF is measured by group efficiency.It can eliminate infeasible solution which there is no machine in the cells.The new algorithm is experimentally demonstrated using several well known CF examples from the published literature.

Key words: cell formation, optimum number of cells, fuzzy algorithm, validity function
