Opportunistic Maintenance Engine Simulation OMENS III.
Abstract
OMENS III simulates the operation of a single engine through a very long period of future time. In operating over this extended period, the engine must be removed for repair from time-to-time. Repairs become necessary on the engine when one of the modules fails prematurely or whenever it requires replacement of an internal life-limited part. The model tracks all the engine removals and all replacements of each module and offending life-limited part through future simulated time. Records are kept through simulated time of the number of removals and the reasons for removal for each module and for the engine. Reasons for removal include (1) premature failure of one or more parts, (2) reaching the scheduled operating time limit, (3) being screened out due to the opportunistic maintenance policy. The model has improved and revised the earlier version (OMENS II) by adding the capability of screening individually by parts instead of by module, as well as separate base and depot screens. The model also computes maintenance, pipeline, parts costs, and transportation costs associated with the forecasted removals and aggregates the costs for any desired life cycle period (in years) to aid in selecting that optimal maintenance policy which produces the least total cost.
