一类复杂闭环供应链多级库存系统的最优控制策略

利用排队理论,构建了一个回复中心、多个回复站组成的复杂再制造多级库存系统模型,并给出了该系统的最优控制策略。数值分析表明,随着回收率的增加,订货成本减少,但是总库存成本并非单调递减,呈先降后升的趋势,同时,回收率对回复中心订货批量的影响要大于对回复站的影响。此外,可回复率和单位缺货成本对系统也具有重要的影响。

Assessing supply chain risks with the analytic hierarchy process: Providing decision support for the offshoring decision by a US manufacturing company

This paper reports the process used by a US manufacturing company to assess supply chain risks within the context of an offshore sourcing decision. The case study company was faced with the objective of finding a new supplier for two of its major product lines. Five alternatives were considered: (1) sourcing finished goods from Mexico; (2) sourcing finished goods from China; (3) sourcing parts from China and assembly in the US; (4) sourcing parts from China, assembly in a Maquiladora in Mexico with investment; and (5) sourcing parts from China, assembly in a Maquiladora in Mexico with no investment in the venture. To find the best solution, action research methodology was combined with the application of the analytic hierarchy process (AHP). Through iterative and structured discussions, 17 risk factors were identified, which were subsequently grouped into main and sub objectives. AHP was then used to evaluate the importance of each risk factor, and to determine the best alternative. This study makes several contributions to the field of purchasing and supply management. First, it provides a comprehensive framework of empirically derived risk factors to be considered in an international sourcing context. Second, it shows how AHP can be used to assess these risk factors and alternatives as part of the framework to facilitate and support the final offshoring decision. And third, it illustrates the successful application of the approach by a US manufacturing company. As such, this paper contributes to the research streams of offshoring and risk management in purchasing and supply, as well as to decision-making under uncertainty and AHP. In addition, it serves as a practical methodology for firms in similar situations.     

Drivers and barriers to environmental supply chain management practices: Lessons from the public and private sectors

This study explores the factors that drive or hinder organisations to implement green supply chain management initiatives. A literature review identifies the main categories of internal and external drivers of green supply chain management practices, including organisational factors, regulation, customers, competitors and society, but there is little indication of suppliers as drivers for green supply chain management. Internal barriers include cost and lack of legitimacy, whereas external barriers include regulation, poor supplier commitment and industry specific barriers. An explorative study is conducted based on interviews from seven different private and public sector organisations. Encouragingly, across the organisations, more drivers than barriers to environmental supply chain management are identified. Organisations seem to be more influenced by external rather than internal drivers. The barriers to environmental supply chain management experienced by organisations tend to be both internal and external.

探析汽车企业如何在全球范围内合理化供应链的理论基础

借鉴供应链管理中的系统思想、需求驱动思想、合作共赢思想、同步运作与动态重构思想,分析研究汽车企业在全球范围内合理化供应链的理论基础:供应链作为一个具有特定功能的有机整体,是基于一定的市场需求而产生和变化的;用户的需求及其变化是企业合理化供应链和供应链动态可重构的驱动源;供应链各成员企业之间基于"竞争-合作-协调"机制,以分布式企业集成合作、协调同步运作为保证,在价值增值链上达到共赢的目标。
