| 摘 要： | 针对现代地空导弹武器系统维修时间不服从指数分布的特点，在系统寿命、预防维修时间和修理时间均服从一般分布的情况下，研究了系统的不完善预防维修策略问题。利用半马尔可夫过程建立了不完善预防维修模型；给出了不完善预防维修可用性的计算方法；在系统稳态可用性最大化原则下，提出了一种判别是否采用预防维修的有效方法。

| Abstract: | Maintenance time of modern ground to air missile weapon systems don't submit exponential distribution. In this case, the method of imperfect preventive maintenance is studied under the circumstance of system life and maintenance time submitting general distribution. The paper uses semi-Markov processes to build an imperfect preventive maintenance model, and gives a calculation method of availability in imperfect preventive maintenance, and finally offers a simple method in distinguishing whether or not adopt preventive maintenance under the rule of maximization of system steady state serviceability. |
