【摘要】 根据已有供应链绩效评价指标体系和样本数据,将专家判定分类结果作为约束条件,建立主观与客观有机结合的供应链绩效综合评价改进型投影寻踪模型(MPPC)。对两个案例的实证研究结果表明,MPPC能很好地应用于供应链绩效的综合评价,模型数学意义清晰,应用便捷,为显性、线性模型,直接揭示出了供应链绩效优劣与评价指标之间的线性关系。在此基础上,剖析了现有的供应链绩效评价BPNN建模过程中存在的问题,模型没有泛化能力和实用价值。实践中,应优先推荐使用MPPC模型进行供应链绩效评价与实证研究。更多还原

【Abstract】 In this paper according to available index system and sample data of supply chain performance evaluation and with the expert classification as the constraint, we built the modified projection pursuit model for the performance evaluation of supply chain. Then through two case studies, we demonstrated the effectiveness of the model. At the end, on such basis, we analyzed the problems existing in the building process of the model.更多还原
