Reliability-Based Robustness Modeling Approach for Manufacturing System Design Based on Fuzzy Design Axioms

A poorly designed manufacturing system can foul the quality of even well-designed products, and a robust manufacturing system is the prerequisite to produce the reliable product. Aiming at developing reliability-based robustness analysis in manufacturing system design, this paper proposes a new approach to model the robustness of manufacturing system in design. Firstly, a metric model for the index of manufacturing system robustness is built based on the information axiom and independence axiom of Axiomatic Design. Next, the quantitative computation approach of manufacturing system robustness by means of fuzzy theory is achieved. Finally, the validity of the proposed method is verified by a case study a reliability-based robustness analyzing example of a furniture manufacturing system.
