Research on Model and Simulation for the Military Aircraft Availability

使用可用度是军用飞机战备完好性的重要度量标准.运用传统的解析法计算使用可用度有其弊端.以军用飞机使用及维修保障过程中各个系统要素为基础,建立了使用可用度概念模型;根据概念模型运用仿真软件Extend建立了仿真模型.仿真结果表明：模型运行稳定可靠,模型中各模块算法合理有效,实现了模型解算目标,可信度高,为飞机可用度研究提供了一种新方法.

The operational availability is one of the important measures of the readiness for military aircrafts. However, the classical analytical method for calculating the operational availability has its short points. A conceptual model for operational availability is developed based on extensive system factors existing in the operation, maintenance and support procedures of military aircrafts. Based on this conceptual model and by using the software tool Extend, a simulation model is built. The results from the simulation show that the model runs stably and reliably, which validates its modular system of algorithms. The analytical objective of the model is achieved with high credibility, thereby providing a new method for the investigation of military aircraft availability.
