Interdependency Analysis for the SUDEMIL Framework

This paper aims to explore an analytical methodology to identify, quantify, and assess the interdependencies across Defence capability development projects, products and programs. To represent the service complexities of project/product interdependencies, a graph theory method is applied. With a network analysis approach, the relative importance and criticality of each project/product are computed according to the graph structure using several models, including a modified Page Ranking algorithm, a node weight balance model, and a degree based algorithm. The preliminary results have shown that the proposed modelling method has the potential to provide a structure and methodology for quantitatively evaluating Defence program interdependencies. The use of the analysis and supporting visualisation tools will enhance the awareness of program interdependencies and provide a decision-aid for identifying program/project/product development priorities, gaps, risks and issues in the interdependency context.
