摘要

This paper investigates the problem of designing cellular manufacturing systems incorporating several design features including multi-period production planning, sequence of operations, alternate process routings, intra-cell layout, dynamic system reconfiguration, duplicate machines, machine capacity, lot splitting, and material flow between machines in a dynamic environment. The problem is formulated through a comprehensive integer linear programming model. The objective is to minimise the total costs of inter-cell material handling, forward and backward intra-cell material handling, machine operating, machine maintenance and overhead, cell reconfiguration, outsourcing and inventory holding. The main constraints are demand satisfaction, cell size, machine availability, machine time-capacity, material flow conservation and machine location. Computational results arc presented by solving some numerical examples to verify the model performance and illustrate its advantageous aspects.
