多目标规划下大型客机研制多供应商选择模型

摘要

Traditional aircraft supplier selection method is typically only a single selection process , which has defects , such as"less targeted","no optimal number for vendor", etc.Based on the classification of large aircraft suppliers , purchase cost , penalty cost , product quality , the average delivery period and advanced technology were used as evaluation index .A multi-ob-jective programming model with price discounts was built , and the modeling method based on genetic algorithm was put forward to minimize the comprehensive evaluation index .The effectiveness of model and algorithm was verified through numerical examples .%针对传统客机供应商选择方法通常只面向单一供应商的选择过程，存在针对性不强、无法进行供应商数量优化等缺陷，在对大型客机供应商进行分类的基础上，以采购成本、惩罚成本、产品质量、平均交付期和技术先进性为评价指标，以最小综合评价值为目标，建立了存在价格折扣的多目标规划模型，并提出了基于遗传算法的模型求解方法。通过算例分析验证了该模型和算法的有效性。
