Measuring supply chain efficiency based on a hybrid approach

Supply chain management has a tremendous impact on the success of a company. One of the critical issues for gaining competitive advantages for companies is improving supply chain performance. Most studies about the application of Data Envelopment Analysis (DEA) Supply chain models do not identify the benchmarking units for inefficient supply chains. On the other, measuring the short run and long run of the supply chain efficiency is another challenge for decision makers in supply chain management. Hence, we propose a methodology of DEA for measuring of the supply chain. We integrated two approaches as special cases of the hybrid model and compare the short and long run strategies of supply chain and can be identified benchmarking.

The benefits of a monitoring strategy for firms subject to the Emissions Trading System

This study tests the impact of Internal and External Environmental Management on performance in firms subject to the European Union’s Emissions Trading System (ETS). A conceptual model is drawn up based on the existing literature, and tested on a large sample of Italian firms. The unit of analysis is single firms subject to the ETS that are involved in Green Supply Chain Management (GSCM). The ETS mechanism has been shown to be marginally beneficial for some firms while supply chain relationships are also influenced by such system. Firms need to identify suitable practices to boost the effectiveness of their environmental strategies. We propose the implementation of a monitoring strategy as a useful practice for firms to be environmentally and economically better off. Our results show that firms subject to the ETS should rely on their own (internal) Environmental Management alone for improving environmental performance, as collaboration with suppliers only has a positive impact on economic performance. However, implementation of a monitoring strategy allows a firm subject to the ETS to partially offset the inefficiency created by the system. We show that environmental collaboration does not become more effective when a monitoring practice is put in place.     

基于供应链管理的库存优化分析

对供应链管理库存控制多级问题进行分析,研究了两种多级库存策略,基于成本优化的多级库存策略,基于时间优化的多级库存策略。两种策略反映了库存管理的一般思想,即库存控制的最优化目标不仅是供应链环节中某一个或几个节点企业的库存最优化,而是整个供应链环节有机、协调地一体化库存的最优化。在此基础上提出了基于时间的多级库存成本优化思路。     

改进电气化铁路供电段设计的建议

根据铁路跨越式发展的新形势,提出改进电气化牵引供电段设计的建议。供电段设计应逐步向规模小、管辖里程范围大、配备检测抢修设备更先进的方向发展。供电段设置以环保为宗旨,提倡节约用地、减员增效,以高效快捷、安全运营为目的。

呆木对供应船线性水动力导数影响的研究

以供应船为研究对象,采用CFD商用软件FLUENT,结合动网格技术对平面运动机构(PMM)试验进行了数值模拟,得到不同呆木面积所对应的船舶水动力,进而获得相应的线性水动力导数,并分析了数值计算结果的合理性,得出水动力导数随呆木面积变化的趋势图。该结论可以为供应船舶操纵性能预报以及呆木设计的研究提供一定的参考。     

港口企业开展物流金融业务的模式及意义

我国港口货物吞吐量和集装箱吞吐量已经连续多年居世界第一,但我国港口大而不强,还是以传统的仓储、搬运等物流活动为主,缺少增值服务,港口之间的竞争也越来越体现为其所在的供应链之间的竞争,因此发展融入港口供应链中的物流金融增值业务,是增强港口竞争力和盈利能力的重要途径.本文研究了物流金融概念,港口企业开展物流金融业务的模式及意义.     

Build-to-order supply chain network design under supply and demand uncertainties

Supply chain disruptions are unintended, unwanted situations resulting in a negative supply chain performance. We study the supply chain network design under supply and demand uncertainty with embedded supply chain disruption mitigation strategies, postponement with downward substitution, centralized stocking and supplier sourcing base. We designed an integrated supply-side, manufacturing and demand-side operations network in such that the total expected operating cost is minimized. We modeled it in a deterministic equivalent formulation. An L-shaped decomposition with an additional decomposition step in the master problem is proposed. The computational results showed that parallel sourcing has a cost advantage against single sourcing under supply disruptions. In addition, the build-to-order (BTO) manufacturing mitigation process has its greatest impact with high variations on demands and is integrated with the component downward substitution. Lastly, the manufacturer needs to order differentiated components to cover its requirement for maximal product demand to prevent the loss of sale, even with fewer modules in stock.
