System dynamics model for flow time and lot sizes optimization according to Quick Response Manufacturing (QRM) strategy

Abstract

[EN] The aim of this paper is to propose a simulation model based on system dynamics and the elements that compose the Quick Response Manufacturing (QRM) strategy. The developed model is a very useful decision-making tool as it helps to obtain process flow times and lot sizes in manufacturing environments whose competitive strategy focuses on markets that demand wide variability and product customization. By simulating four different scenarios, the effects of variability and machine resources utilization are evaluated. The results show that a minimal change in machine resources utilization strongly impacts process flow times and, consequently, another critical QRM variable like Manufacturing Critical-Path Time (MCT).
