Cost tolerance sensitivity analysis for concurrent engineering design support

摘要

This paper presents cost tolerance sensitivity analysis (CTSA),a novel method of determining which features are critical and non-critical early in the design phase when cost information is uncertain.the method utilizes minimum cost tolerancing methods combined with designed experiments to determine which fearures are sensitive or insensitive to uncertinties in the cost-tolerance curve estimates.the method successfully identified critical and non-critical dimensions on the case study of a windmill transmission.The results also show that both cost and tolerances must be considered simultaneously,and examination of near optimal solutions improves the results.
