Abstract: To maximize the availability of equipment furthest, overhauling work is necessary, so opportunity decision becomes an important problem. Number of components, life distributions and corresponding maintenance policy are impact factors of availability to the complex equipment. Taking the combination policy of preventive maintenance and corrective maintenance, the availability expression of single equipment about overhauling opportunity is deduced in the duty cycle, and the further opportunity decision model of equipments system is presented, which considers the effect of working age of components. Lastly, an example is presented to prove that the new model is reasonable and practical.

Key words: military operation, decision-making model, complex equipment, availability, overhauling opportunity
