Abstract: The existing software risk management mainly focuses on all modules of the whole system. To narrow the scope of risk management, the concept of module risk correlation set is proposed to reduce the risk management to the management of related modules. To reduce the system risk analysis to the risk analysis of the module and the correlative module, the module risk correlation is defined and analyzed based on the theory and methods of module coupling, the concept of module risk correlation measure and module risk correlation set is proposed, and the module coupling measure is given. On the basis of this, the solution algorithm model of module risk correlation measure and module risk correlation set is established——the reformative multi-Dijkstra algorithm, the module risk correlation measure is measured, and the module risk correlation set is obtained. Finally, the correctness of the algorithm and effectiveness of the research of related risk module is verified through the experimental results.
