Decision-Making Based on Dempster-Shafer Evidence Theory and its Application in the Product Design

Decision-making is necessary in the process of product design, but in many cases, about the information of decision-making, there are various types of uncertainty, for example, ambiguity, incomplete reliability，ignorance and so on. For making the comprehensive treatment to the various types uncertainty information, this paper proposes a method of decision-making based on Dempster-Shafer evidence theory, and uses a new post-processing method to deal with the results. By means of testing and verifying the new method with specific design examples, and proved the method can be effectually applied in the product design.
