Embodiment 1

[0037]A collaborative decision-making method for product design based on utility and fuzzy theory. Aiming at the ambiguity and distribution of decision variables, triangular fuzzy numbers are used to represent decision variables, and utility functions are used to represent designers’ design experience and preferences. The utility-oriented optimization model uses the genetic algorithm to automatically optimize the solution, ensuring that the design experience and preferences of designers distributed in different places are satisfied under the premise of meeting the designer's decision-making goals, including the following specific steps, as figure 1 Shown:

[0038] Utility determination step (100): for determining the utility of a single decision variable, fitting the engineering data through a utility function to obtain the final utility representation of the engineering data, the engineering data including the utility of a single decision variable and the utility The correspo...

Abstract

The invention relates to a computer collaborative decision-making method and discloses an effectiveness and fuzzy theory based collaborative decision-making method for product design. The collaborative decision-making method specifically includes steps of determining effectiveness; matching engineering data through an effectiveness function to obtain a final effectiveness expression of the engineering data including effectiveness of a single decision-making variable and a designer set corresponding to the effectiveness; optimizing to obtain a general effectiveness target of a single target by the final effectiveness expression as a target; establishing a model by further restraining the general effectiveness target and maximizing the general effectiveness target; solving the model to achieve a final product design scheme. The effectiveness and fuzzy theory based collaborative decision-making method for product design has the advantages of practicality, reliability, easy implementation and great significance for improving reliability in collaborative decision making during collaborative design of products.

Description

technical field [0001] The invention relates to a computer collaborative decision-making method, in particular to a product design collaborative decision-making method based on utility and fuzzy theory. Background technique [0002] The design of complex mechanical products, especially the innovative design is a collaborative design process involving multiple designers. In this collaborative design process, different design experts take on the design tasks of different components or different fields. They consider the tasks from different perspectives, evaluation standards and knowledge backgrounds. Each designer uses their own professional knowledge, design criteria and experience. To complete the design tasks they undertake, but because the design tasks they undertake belong to the same product, there are complex interdependencies between their design objects and the attributes they care about, so these collaborative products The designer of the design cannot be completel...
