Abstract: Determining a comprehensive ranking of the importance of various complex engineering projects is a critical issue in practical engineering decision-making. However, existing methods often overlook the connections between projects and rely on a single analytical perspective, resulting in low differentiation in ranking. This paper proposes a comprehensive project ranking method based on the structural hole theory within the context of a dominating network for complex engineering. First, it introduces the structural hole theory to develop a measurement method for evaluating the breadth of impact of each project. Next, it applies the k-shell algorithm to evaluate the centrality and provides a hierarchical division of the projects, followed by the construction of a global importance evaluation method. Finally, it proposes a comprehensive ranking method by integrating structural hole theory with the k-shell algorithm. The method is demonstrated through an example network and applied to practical engineering projects. A comparison of the project ranking obtained by other methods shows  that the proposed method offers higher discrimination, better adapts to the multidimensional requirements of project evaluation, and more effectively meets the needs of actual management. The findings provide reference for decision-making in complex engineering projects.

摘要：

复杂工程包含的项目众多，对项目的重要性进行综合排序，是工程实际决策亟须解决的问题。然而，现有方法忽略了项目之间的联系且分析视角单一，导致排序结果区分度不高。为此，基于复杂工程支配网络，提出结构洞理论视角下的综合项目排序方法。首先，引入结构洞理论，构建项目影响广泛性的度量模型。其次，利用k-shell算法对项目中心度进行重要性评价及层级划分，构建项目的全局重要度评价模型。在此基础上，融合结构洞理论与k-shell算法，提出项目重要性综合排序方法。最后，将该方法应用于算例网络和实际工程，并与其他方法进行了对比分析。结果显示，提出的项目排序方法具有更高的区分度，能够适应项目评价的多维度要求，为复杂工程的决策提供了参考。
