Supply chain design and operations

供应链的性质在最近经历了重大转变，OR/IE需要的建模建议必须适应已出现的新问题。德勤咨询公司（Deloitte Consulting）最近的一项市场调查得出结论：“不再是企业之间的竞争，而是整个供应链之间的竞争”，建立高效、有效的供应链至关重要；“为你的供应链制定一个战略计划，在当今竞争激烈的环境中发挥作用”，“有效地与供应商、分销商和零售商建立密切联系”。本研究将研究供应链中的长期关系，特别是供应商选择和供应商发展。长期合作关系可能与现货采购形成对比，涉及对特定产品和工艺的联合投资。本研究将结合三个主题：多期合同、竞争，最后是大多数供应链中存在的“权力”结构。我的目的是翻译一些典型的为有竞争的单时期模型或没有竞争的多时期模型开发的工作，以便我们可以研究两者，以及两者对双方同意的合同形式的影响。这些关系的形式反过来又在很大程度上决定了供应链合作伙伴关系中许多运营决策的有效性和效率。

Summary of Proposal for Public Release The nature of Supply Chains has undergone a major transformation in the recent past and the modelling advice needed from OR/IE must adapt to deal with the new issues that have arisen. A recent market survey by Deloitte Consulting concluded "No longer will companies compete against other companies, but total supply chains will compete against other supply chains" and that it is crucial to build efficient and effective supply chains; "develop a strategic plan for your supply chain that works in today's competitive environment" and "effectively establish close ties with suppliers, distributors, and retailers". This research will study long-term relationships in Supply Chains, in particular both supplier selection and supplier development. A long term relationship is likely to contrast with spot purchasing by involving joint investment in specific products and processes. This research will combine the three themes of multiple period contracting, competition and finally the 'power' structure that exists within most supply chains. My aim is to translate some of work typically developed for single period models with competition or multiple periods without competition, in order that we might study both, and the impact that both have on the form of contracts agreed to by the parties. The form of these relationships will in turn determine to a large extent the effectiveness and efficiency of the many operational decisions made within the supply chain partnership.
