There are two aspects to cell formation inflexible manufacturing systems, cell sizing or deciding on the optimum number of machines to be allocated to each cell, and then allocation of specific machines to each cell. Although the latter problem has been investigated extensively there is a paucity of published work on the former. This paper discusses the effects of cell sizing on operational flexibility.Operational flexibility is that aspect of flexibility that enables manufacturing systems to respond with speed and efficiency to changes in the manufacturing environment while maintaining an effective level of control. Due dateThe methodology described in this paper for cell sizing is based on two of the above characteristics, number of operations per job and processing time.It has been stated that no generalised methodology exists for calculating cell size [1,2]. The authors investigations indicate that a methodology based on the specified parameters has wide application and could be extended to various groups of components that are manufactured in a flexible manufacturing environment.
