A Determination Method of Product Design Parameters with Interval Constraint

Abstract:

There are some undetermined parameters that can be get values only in a certain range about products and other objects in the product design rules and calculations. The parameters to be determined are usually affected by many factors and constraints, which are often bound with fuzzy. The problem is solved in the past usually by the designer getting values of undetermined parameters in a limited range based on their experiences. That is inevitable to deal with subjectivity. Two algorithms about solving undetermined parameters are proposed based on evidence theory and fuzzy comprehensive decision-making methods in this paper. The algorithm is as a reasoning method applied in a knowledge-based intelligent system.
