Research on Green Process Optimization Method based on Local Optimization of Process Feature

针对绿色工艺在实际应用中的不足,本文提出了基于产品工艺特征局部优化的绿色工艺优化方法,以及特定产品范围的绿色工艺数据库的构建。围绕产品工艺特征及其工艺方案构建绿色工艺数据库,以支撑工艺路线优化;通过列昂波特相互作用矩阵模型评价、分析产品初始工艺路线集,确定待优化工艺路线及其"问题"工序,并建立局部工艺要素优化模型,对其进行基于工艺特征的工序局部优化,最终在优化后的工艺路线集中决策选择出最优的绿色工艺路线。并通过实例验证了该方法的可行性和有效性。

Aiming at the deficiencies of green process in the practical application, this paper proposed the optimization method of green process routings based on local optimization of process feature and the conception of establishing the green process database for specific product range. For a range of products, the process characteristics and process schemes were focused to build a green process database to support the process route optimization. Then with Leonid Potter interaction matrix model, evaluating and analyzing every process routing in the original set,furthermore the one to be optimized and the processes with"problem"were located .Later an optimization model of local process elements was established to conduct the local optimization of the “problem” processes based on the characteristics. Ultimately the optimal green process route appeared from the set of the optimized process routings. By an example, feasiblity and efficiency of the method were verified.
