在供应链管理(SCM)中,人们更关注于寻找一种系统的方法,能够在计划阶段对可靠度进行评估。提出了一种模糊QFD模型,使其能够在供应链管理的过程中,传达用户需求与设计参数间的模糊关系;同时提出一套模糊的决策程序:模糊多准则决策.用来寻找一组CRT设计中可靠度需求性能的最优解。主要目的是找出合适的可靠性测试等级,以便使每一条供应链中模糊需求与产品生产参数之间的关系更加合理,以满足用户的需求。 相似文献

21世纪的竞争将不再主要是企业与企业之间的竞争。而主要是以IOS等驱动的供应链与供应链之间的竞争。企业需要和供应链上的其他企业联合起来。才有可能赢得广泛的技术、在质量和可靠性方面的快速反应能力以及持续的成本优势。有鉴于此,本文以供应链上企业之间的关系管理为基础.构建了一个IOS在供应链中应用的四阶段模式,并以此为框架,从IOS的设计、建立、应用和受益的过程来分析其因果关系,探讨影响IOS成功的关键变量和相应措施。我们认为。未来IOS将专注于核心竞争力联盟的建立和在联盟中有效地运用竞争力外取策略。 相似文献

Trust and distrust can play an important role in a healthy supply chain collaborative relationship, and both carry potential shortcomings. Little attention has been paid to understanding and explaining the development process of trust and distrust in supply chain collaborations, especially in an international context. Using the Transaction Cost Economics theory, this study begins by discussing expressions of trust and distrust within the context of a supply chain collaboration dyad. Then, we explore how trust and distrust interact at a network level. Using a novel, longitudinal, multi-case-study approach, this paper provides new empirical evidence of the complementary roles of trust and distrust in supply chain collaboration, exploring how these concepts work together across different stages of the relationship and in different contexts. This study distinguishes between ‘competence trust’ and ‘integrity trust’ concerning collaboration contracts which typically create distrust. Finally, this paper offers unique insights into the influence of culture on the interpretation and performance of trust and distrust in international supply chain collaboration, grounded in the context of the Chinese automotive industry. 相似文献

Sustainability issues are particularly sensitive to the fashion supply chain, given current fierce competition, intensive resource use, and the exposure of penurious labour conditions in some regions.In this paper, we discuss how the sustainability movement is impacting the fashion retail supply chain organisation and its performance. We carried out a study with stakeholders of the fashion industry and we report on their views. We elaborate on the challenges and conflicts of the different dimensions of sustainability, and we discuss how to leverage both the internal and external organisations in the European supply chain. 相似文献

A large proportion of consumer returns fall into the category of false failure returns, which refer to returns without functional defects. In this paper, we consider profits resulting from exerting costly effort to reduce false failure returns in a reverse supply chain. The supply chain as a whole has a strong incentive to reduce such returns for cost saving. However, retailers typically enjoy a full credit provided by suppliers for returns, so they may not have sufficient incentives to exert enough effort for supply chain profit maximization. In some scenarios retailers may even have the motivation to encourage such returns. We suggest using a coordination contract to resolve this profit conflict. We introduce a quantity discount contract which specifies a payment to the retailer with an amount exponentially decreasing in the number of returns. We present explicit forms of such contracts given different assumptions about the distribution of the number of returns. We also prove that the contract is Pareto improving. Besides, it is shown that when the contract is applied in a closed-loop supply chain, it can deter retailer's potential incentive to encourage returns. Moreover, some modifications of the contract can lead to easy allocation of supply chain profit. 相似文献

在新一轮科技革命和产业变革浪潮的带动下,智慧供应链正在快速发展,与之相关的城市智慧供应链发展也成为当前供应链研究领域中的重要问题。然而,传统的供应链发展评价指标体系难以直接应用到智慧供应链评价中。为此,本文从企业视角和区域视角出发,从城市智慧供应链基础设施情况、人力资源投入情况、资金投入情况、企业创新情况、供应链效率和效益6个维度构建了中国城市智慧供应链的发展评价体系,设计了基于改进的TOPSIS方法的评价方法,并进行了中国城市智慧供应链发展指数评价,为城市管理部门量化智慧供应链发展水平提供了方法依据。 相似文献
