Abstract:

A new condition-based opportunistic maintenance strategies was presented for multi-unit series and parallel system. Under this policy, degradation model of equipment were modeled using continuous -time Markov chain and the deterioration process of equipment was divided three condition: new, minimal deterioration ,severe deterioration. With a consideration of maintenance economical relation of equipment, maintenance decisions were given based on deterioration states of the equipment. A eM-Plant model of cylinder production line was given on the background of car engine plant equipment maintenance optimization problem. The Monte Carlo simulation model of the equipment maintenance policy based on eM-Plant was also given in detail. By a numerical example,the average maintenance cost of cylinder production line in car engine plant in finite time zone was presented and best decision variants were given under this policy.
