Abstract: This paper describes the development of a process simulation model and integration of the genetic algorithms (GA) with the model as optimisation techniques using a case study of lot sizing problem (LSP) in make-to-order (MTO) supply chain solved by a combined simulation and genetic algorithm (GA) optimisation model. The simulation model is performed using ARENA software. GA model is implemented using visual basic for application (VBA) language because it ensures exchanges between ARENA software and MS Excel. The case study's objective is to determine the optimal solution to determine the fixed lot size for each manufacturing product type that will ensure order mean flow time target. The comparative results with OptQuest software, which is used as a global search method, illustrate the efficiency and effectiveness of the proposed approach.

Keywords: lot sizing; make-to-order; MTO supply chains; genetic algorithms; case studies; iterative simulation optimisation; SCM; supply chain management; process modelling; optimal solutions; fixed lot sizes; manufacturing product types; order mean flow time target; OMFT.
