Study on the Product Development Process Based on WITNESS Simulation

Abstract

The differences of development cycle between product serial and concurrent development process are obtained through simulation in this paper, which implies the importance of rational planning in the process of product development. The models of product serial and concurrent development process are built based on witness. Three types of models for both simple and complex products have been made respectively to simulate ,and then compared results have been got under six different conditions . Among six situations, the results of four are that the time of concurrent process is much shorter than that of serial process; one is that the time is very close; another is that concurrent process is much longer. We draw a conclusion that product development process must be rationally planned in order to shorten the development cycle for some complex products.

Determination of Optimal Production Process Using Scheduling and Simulation Software

“…Witness simulation tool was used to create a universal simulation model for verification and subsequent optimization of handling devices using basic heuristic optimization methods [6]. In 2014, the authors Chen et al utilized the simulation tool to shorten production cycles in developing a new product [7], and a year later, Dyntar and Strachotova applied this tool to design and optimize the supply chain [8]. In 2016, research on using Witness program was aimed at improving material flow continuity [9], planning and layout optimization [10] etc.…”
