中国上市物流公司动态绩效评价及对策

鉴于传统绩效评价方法的局限,本文运用数据包络分析(DEA)法,站在整个物流行业的角度,选取中国深沪两市21家上市物流公司,利用其2002～2005年间的财务数据进行动态绩效评价,得出"中国上市物流企业总体技术绩效不佳,且有逐年下滑的趋势"等结论.最后,根据评价结果分析存在的问题并提出相应对策.     

基于环境责任的闭环供应链网络多准则决策均衡问题

为使闭环供应链网络成员企业在注重利润最大化的同时,在环境保护方面承担社会责任,实现企业物流活动同环境发展相协调,建立了考虑环境指标的闭环供应链网络多准则决策均衡模型。给出了多层闭环供应链网络各层决策者的多准则优化条件、对应的变分不等式公式以及多准则网络均衡条件。最后,通过算例对不同环境排放权重下均衡模型网络中产品生产量、交易量、交易价格及排放量等相关经济指标均衡结果进行对比分析。     

Smart Manufacture Process and Structure for Composite Materials

It is difficult to ensure the manufacturing process of composites for the reason that there are complicated processes during curing process of composites. The cure cycle has a significant effect on the quality of the finished part. The traditional cure cycle based on empirical approach could not ensure the quality of cured products because of unstabilized performance, high cost of production and low efficiency. As complex intelligent manufacturing systems are developed increasingly in industry, the necessity of more userfriendly operation system is becoming progressively importance for their utilization and market value. This paper introduces some of the recent technological advances in the intelligent manufacturing systems that will influence the design and development of relevant industry.
