The decision-making of process planning is not only affected by manufacturing resources (such as machine tools, cutting tools, fixtures, inspection tools, measuring tools), but also restricted by processing methods, process constraints and other factors. At the same time, it is also related to product type, product batch size, design level of process personnel and even enterprise process habits Nonlinear programming problems with multi factor constraints [6,7]. Using traditional methods (such as Newton method, gradient descent method, graph theory method) to carry out process planning decision-making has the defects of low efficiency, time-consuming and easy to fall into local optimal solution [8-10]; moreover, this static process planning can not adapt to the dynamic change of enterprise manufacturing resources, resulting in the efficiency of process route greatly reduced or even invalid. In recent years, with the development of artificial intelligence, scholars at home and abroad have proposed a variety of optimization algorithms, such as Hopfield neural network, genetic algorithm, grey correlation method, ant colony optimization algorithm, tabu search, particle swarm optimization algorithm, etc., and a large number of research results have been achieved [11-14]; however, due to the defects of each algorithm, as well as the impact of product diversity and changes in manufacturing resources, a single optimization is adopted The algorithm has some limitations and is difficult to achieve the desired results, so it is necessary to adopt the algorithm mixing or the complementarity of different optimization mechanisms to improve the optimization efficiency<br>
