摘要/Abstract

摘要： 实际生产过程中，影响加工成本的因素很多，很难用一个统一的数学模型来精确描述所有类型的加工成本-公差关系。以产品加工成本与质量损失成本之和最小为优化目标，以产品性能偏差与经济加工精度为约束，建立了产品的公差优化模型；然后采用遗传算法对优化模型进行求解；最后以某型号汽车空调压缩机为例验证该模型的有效性。

关键词: 公差成本, 性能偏差, 遗传算法, 公差优化

Abstract: Based on the actual production processes, there were many factors that affected the processing costs, it was difficult to use a unified mathematical model to accurately describe all types of processing costs-tolerance relationships, the product processing costs and the quality loss costs were regared as targets, the product tolerance optimization model was established and with the restriction of product performance deviation and economic machining precision. GA was used to solve them, and finally a type of automotive air conditioning compressor was to be an example to verify the validity of the model.

Key words: tolerance cost, performance deviation, genetic algorithm(GA), tolerance optimization
