以最低制造成本为优化目标，介绍了求解装配尺寸链的综合因子法、最低成本法和线性规划法，为合理分配装配尺寸链中各环公差提供参考。
Taking the lowest manufacturing cost as the optimization objective, the comprehensive factor method, the least cost method and the linear programming method for solving the assembly dimension chain are introduced, which can provide a reference for rational distribution of the tolerances of each ring in the assembly dimension chain.
