| 摘要： | The requirement for high availability of critical infrastructure necessitates the use of correct maintenance approaches for each system that supports the DOD missions. This thesis used a risk-adjusted cost method as the means to analyze the suitability of maintenance approaches, namely the no-preventive maintenance approach, the time-based maintenance approach, and the condition-based maintenance approach for different critical infrastructure. These three maintenance strategies were implemented using appropriate types of contracts and proper configuration management for the critical infrastructure. A sensitivity analysis was conducted, which validated Koenemans 2009 findings for ships that condition-based maintenance can result in a significant increase in operational availability as compared to the no-preventive maintenance approach, and a larger increase as compared to the time-based maintenance approach. This validation of the sensitivity analysis performed for critical infrastructure shows that the use of condition-based maintenance results in higher availability than either the time-based or no maintenance-based strategies. |
