The Research On Evaluation And Decision Of Product Conceptual Design Based On Decision-Maker Satisfaction

In the development of the products,the conceptual design decisively influences the follow-up detailed design,the production and development of the products,the marketing of the products and the realization of the strategic objective of the enterprises in the process of designing the products.Therefore,we must select the best plan in the phase of conceptual design,then carry out the follow-up design based on it.The products produced will meet the needs of the fierce market competition.To gain success of the product development,the opinions and support of the decision makers of the enterprises are critical.To make evaluation and decision of the conceptual design according to the strategy of the development of the enterprise and the opinions of the decision makers is an important link of the product development.From the satisfaction of the decision makers,this paper provides a set of evaluating and decision-making methods of the conceptual design of the products based on the satisfaction of the decision makers through researches on the current theoretical system of the evaluation and decision-making.Through the researches on the decisions and decision makers satisfaction,this paper analyzes the expected values of the various categories of the product concepts of decision makers, and establishes the desired objectives of the decision makers according to the researches on the basic elements of the conceptual design of the products and the theories of certainty decision and risk decision.Then the decision makers evaluate the various categories of the different conceptual designs and obtain the comprehensive evaluating indexes of different designs through VTs method.By matching the comprehensive index with the objective index of the conceptual design of the products we can get the design which is most close to the objective index and get the selected design for further development.And through the comparison of the design and the objective index,we can also get to know what need to be improved.Finally,this paper applies the research results to the evaluating and decision-making of the conceptual design of Sany Automobile Crane,and verify its effectiveness and practicability.
