Research on project portfolio selection of maritime search and rescue system-of-systems construction based on dominance and multi-domain relationship

Abstract

Project portfolio includes numerous projects and there are interactions and dependencies between projects. To overcome the shortcomings of traditional project portfolio evaluation methods, this paper proposes a project priority ranking method based on complex network theory and PageRank algorithm. This paper firstly analyses the dominance relationships among projects based on the establishment of evaluation criteria for projects; furthermore, deliverable-To-project multi-domain matrix (MDM) is established to measure the dependency relationship between projects based on design structure matrix (DSM). Considering the dominance and dependency of projects, this paper constructs a priority ranking model for projects based on the PageRank algorithm. Finally, taking the project portfolio selection for the construction of maritime search and rescue (SAR) system-of-systems (SoS) as an example, the ranking problem is discussed.
