A Simulation Optimisation Tool and Its Production/Inventory Control Application

JaamSim is a prominent, discrete-event simulator with an established and fast growing community of users.To the authors' knowledge, no simulation optimisation package was available for JaamSim up to now.For the purposes of this research, we developed the open-source software JSOptimizer that can be used to optimise simulation models of complex engineering systems built with JaamSim.The proposed tool utilises the jMetal framework, a well-known and validated library of meta-heuristic optimisation algorithms.The contribution of this article is twofold.First, we present the most important aspects of the proposed software JSOptimizer.Secondly, we examine a novel, multiobjective problem pertaining to a stochastic manufacturing system which involves production control and job routing decisions.Several instances of the optimisation problem are solved and the resulting local non-dominated sets are compared under various performance metrics by utilizing the functionalities of JSOptimizer.This investigation also serves as a proof of concept for the proposed software's applicability.
