WitnessBased Simulation and Optimization of Production Lines in a Manufacturing Plant

Abstract

Abstract: As a case study, this paper addresses the redesign of a pillar manufacturing production line in a plant. By using the theories of constraints（TOC）and drumbufferrope (DBR) method, a simulation system is developed for the production line based on Witness software. Then, by simulation, the factors that affect the performance of the line are analyzed. In this way, the line is redesigned and reconfigured such that the material handling process is optimized, machine utilization is improved, and production efficiency is increased. Consequently, the productivity of the line is increased by 497% without additional equipment investment.

Key words: witness software, production line, simulation, optimization, theory of constraints
