Abstract :
Throughout these years, with the high demand for system safety, operational efficiency and life cycle cost control, decision support systems that balance among such requests for complex system maintenance were brought forward. This paper illustrated a newly developed influence diagram decision model which integrates current states, decision actions, decision objects and cost analysis to facilitate the maintenance strategy decision making. At first, the network structure of the influence diagram is proposed. Then the conditional probabilities and the utility values of each kind of costs were elaborated. At last, the procedure for implementing maintenance decision influence diagram model was demonstrated based on a case study. With the input of current states, this model could provide the recommendations and relevant supportive information for the purpose of cost budgeting. In order to verify the model´s reliability, costs from different decisions are listed for comparison.
