مرکز منطقه ای اطلاع رساني علوم و فناوري - A comparative simulation study of production control systems

Abstract :

In this study, performances of push, pull and synchronous production systems are investigated over a hypothetical serial line that consists of five work stations. The effects of four factors, i.e., work in process inventory level, system’s output rate and flow time, on the system performance measures were tested conducting experiments via simulation models of push, pull and synchronous production systems. At the result of the experiment, optimized push, pull and synchronous production systems generated same quantity of system’s output at the different level of work in process inventory. Kanban, constant work in process (CONWIP) and drum-buffer-rope (DBR) systems gave better performance than other systems’ performance. Kanban, CONWIP and DBR systems were compared with each other. This comparing showed us the best production system is changing at every scenario. The performances of the systems depend on the factor levels. To determine the best factor levels combination for Kanban, CONWIP and DBR systems the method of graphical representation of factors effects was used at this study.
