Simulation on System Operation and Maintenance Using System Dynamics

Abstract

System operation and maintenance always depends on system components' characteristic. Further, components which build a system yield unique system behaviors beside the components operation and maintenance condition. The research objective is to identify and understand behavior of component and as well behavior of system under various operation and maintenance policies. It is directed to give policy options to the management as decision maker and further, inform likely impacts of those options. This work presents a user friendly and easy system to simulate the effect of various operation and maintenance plans to the system reliability, operation cost, and maintenance cost For each plan of operation and maintenance, this simulation models failure rate, time to maintain, decision whether to maintain or not, degree of how good maintenance done, effect of component after maintenance to the system, maintenance cost, and operation cost A case study of main engine cooling system is presented using previous works data [1] . The simulation shows prognostic results for a given scenario of system configuration, operation, and maintenance plan.
