Simultaneous Optimization of Tool Allocation and Work Sequencing in Parallel-Type FMS

Abstract

Integration of several machining processes in response to a wide variety of needs in machinery industries has expedited the implementation of robotized flexible manufacturing systems even in the SME manufacturers for the last decade. This study extends our previous work on building a tool allocation problem in parallel-type FMSs and proposes a simultaneous optimization model for cutting tool allocation and job sequencing. We show that the proposed decision-making approach can outperform the conventional two-phase approach in minimizing total completion times through a series of computational experiments.
