Abstract: It is possible for the projects undertaken by different enterprises to take advantage of complementary resources when they are constructed simultaneously in the same region. If the possibility is rationally used by the enterprise, the project can obtain further optimization. Therefore, how to choose the best partners needs to be studied. This paper illustrates the formation mechanism of resources complementarity from the point of cooperative game theory and analyzes the decision-making characteristics of the partner selection problem. A partner selection model is established by using bi-level programming. A solution method based on expected profit constraint selection is applied to solve the model. A case study on the construction plan optimization of reclamation for a port industrial park is used to verify the model and its solution. The result shows that, by using this method, the time and cost of the reclamation can be effectively saved compared with the original plan.

Key words: partner selection, bi-level programming, resources complementarity

摘要： 当不同企业承担的工程项目在同一地区同时开展时,彼此间经常会存在工程资源互补的可能,如果加以合理利用,便能够使项目的实施进一步得到优化。因此,企业如何选择有资源互补潜力的最佳合作伙伴有必要予以研究。文中从合作博弈的角度阐述了资源互补的形成机理,定性分析了伙伴选择问题的决策特征;运用双层规划构建了基于资源互补的项目伙伴选择模型,提出了基于期望收益约束选择的求解方法。最后以某临港产业园区填海项目与其他项目的资源互补为例,采用文中提出的模型及求解方法优化施工方案,得到降低建设投资、缩减施工工期的优化效果。
