J. Clark School of Engineering Department of Civil and Environmental Engineering 7b Risk Analysis for Engineering Department of Civil and Environmental Engineering University of Maryland College Park chapman hAll cRC CHAPTER 7b. RISK CONTROL METHODS Slide No. Risk-based Maintenance Management Maintenance Methodology - Maintenance of a structural system can be performed through the use of risk and economic concepts. -A marine system is chosen to illustrate the these concepts. - The methodology described herein is referred to as Risk-based Optimal Maintenance Management of Ship Structures ROMMSS as described by Ayyub et al. 2002 . CHAPTER 7b. RISK CONTROL METHODS Slide No. Risk-based Maintenance Management Maintenance Methodology cont d - Systematic quantitative qualitative or semi-quantitative approaches for assessing the failure probabilities and consequences of engineering systems are used for this purpose. - The ability to quantitatively evaluate these systems helps cut the cost of unnecessary and often expensive re-engineering repair strengthening or replacement of components subsystems and systems. 41 CHAPTER 7b. RISK CONTROL METHODS Slide No. Risk-based Maintenance Management Maintenance Methodology cont d - The results of risk analysis can also be utilized in decision analysis methods that are based on cost-benefit tradeoffs. -ROMMSS The ROMMSS is essentially a 6-step process that provides a systematic and rational framework for the reduction of total ownership costs for ship structures. The basic steps followed for the ROMMSS strategy are shown in Figure 12. CHAPTER 7b.
