Unformatted text preview: ng general loss functions. General loss in this paper means an arbitrary polynomial function of a certain degree. We also briefly review the current work that has been made on solving the tolerance allocation problem. Keywords: Tolerance allocation, quality loss, discrete optimization. 1. INTRODUCTION As competition between manufacturing industries progresses, it becomes increasingly more important that the products be manufactured at a low price and be of generally high quality. Otherwise, customer confidence cannot be maintained. The variation of individual parts accumulates when they are assembled, and affects the variation of critical measures on the product, such as the gap between a door and a fender on a car. These relationships can be analyzed by CAT (Computer Aided Tolerancing) software. Adjusting individual part tolerances can reduce the variation of critical measures. However, this often results in a higher manufacturing cost. Tolerance allocation consists of choosing the tolerances in an optimal way...
