JOINT OPTIMIZATION OF PROCESS MEAN AND TOLERANCE LIMITS FOR MULTI-CLASS SCREENING

摘要

Most models reported in the literature treat the determination of process mean andtolerance limits as two separate research fields. In this paper, the problem of jointly determining the optimum process mean and tolerance limits for each market is considered in situations where there are several markets with different price/cost structures. A profit model is constructed which involves selling price, production cost, penalty cost, and inspection cost. A Taguchi's quadratic loss function is utilized for developing the economic model for determining the optimum process mean and tolerance limits. A numerical example is given.
