Investigating product development process reliability and robustness using simulation

Abstract

This paper uses the design structure matrix to model and simulate the performance of product development processes. Although simulation is a powerful tool for analysing process performance, its ability is limited by the availability of accurate input information. Design structure matrix simulation requires process data that is hard to assess or estimate directly from development participants. In this paper, we propose a methodology that allows a more practical estimation of an important simulation input parameter: rework probability. Furthermore, we show how this assessment method (combined with simulation) allows managers to evaluate process improvement plans based on two resultant process measures: reliability and robustness. The method is illustrated with a real application from the automotive industry.
