استفاده از روش كيني و ريفا براي بهينه سازي چند پاسخه در چار چوب روش سطح پاسخ (RSM)

ln this paper response surface method (RSM) is explained initially as one of the most important tools of quality improvement, then a review of the literature is presented in relation with the optimization of the mufti-responses within RSM framework. Attempts are classified in three groups: loss function, desirability function. and classic methods. Then each item will be discussed usefully. Since the method of the utility function considers the decision-makerʹs opinions objectively, it is quite important. It should be noted that the function of common utilities being used ill RSM is in fact L-P metric formula. The relationship between quality attributes and their respective effects are not taken into account by it. Since it is important to provide aid circumstances and guidelines for decision-makers in the discovery of the solution. Raiffa and Keeneyʹs method is effective in this respect. Thus. this method is used to obtain utility function and finally tu determine a satisfactury sulution. The efficiency of the mentioned methud is illustrated by an example.
