Reliability evaluation of collaborative product design process considering redesigning activities

Abstract

During the product design phase, due to various factors and random failures, input materials processed might be defective and would be less than input amount. In order to increase the output, defective products are usually formed as a reverse product flow and redesigned. However, these activities would cause an increment of the design capability and processing time for the design entities. The objective of this research is to propose a reliability evaluation model and solution method that would determine the reliability for the product design phase with reverse logistics product re-designing activities. The evaluation model contains design capability and processing time two aspects and the whole system reliability can be derived afterwards. Finally, a case study is presented to illustrate the usefulness of the proposed approach. © 2013 Asian Network for Scientific Information.
