QUALITY LOSS FUNCTION BY ROBUST TOLERANCE DESIGN AT THE OPTIMAL COST
George DRĂGOI, Daniel BRISSAUD, Miha JUNKAR, Costel Emil COTEŢ
Abstract: The paper addresses the issue of the achievement of the quality by robust tolerance allocation at the minimum cost. This model proposes an optimization model taking into account the process capability by determining the optimal tolerance combination considering dependent variables for tolerance design. The basic idea is that product functions are combinations of part characteristics and the client view is a function of the overall product. This model enables the process design not only to predict scrap rate in accordance with the tolerances allotted, but also to minimize the total quality loss due to the dependence of parts on the life-cycle of the product.
Key words: quality loss function, dependant variables, robust tolerance design, optimal cost.
