The optimization of production system using simulation optimization tools in witness

Abstract

The paper highlights the problem of the use of computer simulation optimization aimed at increasing the efficient production of manufacturing and production systems. The paper presents the possibilities of making use of simulation optimization in the form of a simulation study that was performed within the framework of cooperative ventures between our workplace and an industrial partner. The aim was to use the Witness environment for the determination of the optimal number of machines for individual workstations or respectively, to establish the optimal number of production shifts for these workplaces in the production line of short- barrels for pistols in gun-maker company. The Witness Optimizer package was applied to this optimization problem. We used Hill Climb optimisation algorithm, which this package offers. The objective function includes the production quantity, and machine and staff costs. The optimization parameters and their range of variation were proposed on the basis of the predefined requirements of the entrepreneur.
