Analyze and Research on the Fitness Model of Tasks Assignment in Mechanical Product Design

To realize the optimal selecation and allocation of resources in the process of product design task allocation and improve the quality of product design, the definition and calculation formula of product design fitness was analyzed and given. Based on the analysis of product design task allocation, the muliti-objective optimization mathematical model of product task redistribution according to the characteristics of parallel tasks assigned; The effectiveness of proposed model was verified by example of a certain engine design task allocation in a car factory.
