Approach to achieve high availability in critical infrastructure

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 Koeneman’s 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.
