Estimation design rework efforts in the early phase of design and development

Abstract

A design rework efforts estimation (DREE) framework is developed in order to identify design rework efforts in the early phase of product design and development. An automotive water pump is used as a case study in this paper. Dependency among components, which are assesed numerically by Analytical Hierarchy Process (AHP), is a key driver on design rework efforts estimation. And then, Work transfer matrix method (WTM) is a mean to estimate design rework efforts. Results based on worst case scenario were validated with experts from an engine manufacturer. © 2010 Springer-Verlag London Limited.
