| 摘 要： | 针对多个加工方案的选择和优化问题，建立了基于粒子群算法的多目标优化数学模型.以生产成本、生产时间、加工质量和生产利润为主要评价指标，利用层次分析法建立阶梯层次模型，根据决策者对各评价指标的不同要求确定了权重.将该方法应用于某汽车变速器四档中间轴齿轮的加工过程中，采用粒子位置取整操作的编码方式，用改进粒子群算法和层次分析法的混合算法进行求解.实例结果分析表明，多目标优化模型能够简单、有效、客观地根据对评价指标的不同要求选择出最优的加工方案.

| Abstract: | Aiming at the selection and optimization of several machining schemes,a mathematical model for multi-object optimization based on particle swarm optimization(PSO) algorithm was established.The production cost,production time,machining quality and production profit were chosen as the main evaluation indexes,and a step heirachy model was established with the analytic hierarchy process(AHP).The weight was determined according to the different demands of decision maker on each evaluation index.The proposed algo... |
