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。
For the traditional airliner supplier selection method is usually only for a single supplier selection process, there is a lack of pertinence, unable to optimize the number of suppliers and other shortcomings in the classification of large passenger aircraft suppliers, based on procurement costs, penalties , Product quality, average delivery date and advanced technology as the evaluation index, aiming at the minimum comprehensive evaluation value, a multi-objective programming model with price discount exists and a model solving method based on genetic algorithm is proposed. The effectiveness of the model and the algorithm is verified by an example analysis.
