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.
