摘要

网络设计是研发项目中最重要的战略决策之一。为了长期高效运行，需要对其进行优化。本文旨在对研发项目的供应链网络进行设计。在此基础上，提出了解决面向项目的供应链管理问题的目标规划模型。提出的模型是为了确定主要承包商、执行者和项目实施的各种备选方案的最佳组合。该模型优化了研发项目全生命周期的时间、成本和可靠性。最后以一个案例来验证和说明所提出的模型。案例研究中成本和时间高的主要原因是供应商和顾问网络的选择不正确。通过数值数据对模型进行了验证，结果表明该模型对项目导向组织的生产力有显著的促进作用。该模型可以为研发项目的管理者和决策者提供指导，使他们能够确定组织中最佳的供应链网络来解决和改进问题。它也为研究人员在研发项目中继续研究供应链管理提供了有用的基础。

A mathematical formulation of time-cost and reliability optimization for supply chain management in research-development projects

One of the most important strategic decisions in Research-Development projects is network design. It needs to be optimized for the long-term efficient operation. This paper aims at designing the network of Supply Chain for R&D projects. Accordingly, it proposes a Goal programming model for solving a Project-oriented Supply Chain Management problem. The proposed model is developed to determine the optimal combination of the main contractors, executers, and various alternatives for project implementation. The model optimizes time, cost and reliability in the whole lifecycle for the R&D projects. A case study is presented to validate and illustrate the proposed model. The main reason for the high cost and time in the case study was due to the incorrect choice of the network of suppliers and consultants. The model has been tested by the numerical data, revealing that the model could have a significant contribution to the productivity of project-oriented organization. This model could serve as a guideline for managers and decision makers in R&D projects, enabling them to identify the best networks of the SC in their organizations to resolve and improve problems. It also acts as a useful basis for researchers to continue research concerning SCM in R&D projects.
