Study on Matching Method of Mechanical Products with Multi-parameters Based on Genetic Algorithm

In this paper, the selective assembly problem of mechanical products with multi-parameters is described. Aiming at meeting several assembly precision at same time and minimizing the number of surplus parts, the mathematical model for solving this problem is established. According to the particularity of this problem, a new matching method of mechanical products based on genetic algorithm is proposed and the related issues such as the coding method, the selection operator, the crossover operator and the mutation operator were designed. At the end, an example of applying this algorithm is given to prove feasibility and validity of this matching method.
