The overall objective of the maintenance process is to increase the profitahility of the operation and optiinize the total life
cycle auto without MITI-MI sing safety or environinental issues. Risk assess] nent integrates reliability with safety and environmental issues and therefore can he used as a decision tool for preventive maintenance planning. Maintenance planning based on risk analysis minimizes the probability of system failure and its consequences (related to safety, economic and environment). It helps management in making correct decisions concerning investment in maintenance or related field. This will, in turn. result in better asset and capital utilization.
This paper presents a new methodology for risk -based maintenance. The proposed inethodology is cornprehensive and quantitative.
It comprises three main modules: risk estimation module, risk evaluation module, and maintenance planning module. Details of
the three modules are given. A case study, which exemplifies the use of methodology to a heating, ventilation and air-conditioning
(HVAC) system, is also discussed.
