Design and Implementation of Reliability Simulation Environment Based on Multi-model

为及时和充分地评价设计、制造、使用、环境等因素对系统性能可靠性的影响,为性能可靠性建模与分析提供灵活高效的软件平台,设计开发了一个多模型综合集成的性能可靠性仿真环境(MISER)。它借鉴多种典型的多模型仿真系统和仿真集成思想,支持简单的面向对象的设计与分析,提供多分辨率建模和模型集成,采用报酬变量和活动变量定义常见的和用户自定义的可靠性指标,提供高效率的重要性抽样方案,支持用户扩展和用户自定义模型。最后给出MISER在某激光装置能源模块性能可靠性仿真中的应用。

In order to assess the influence of the factors such as design, manufacture, usage and environment on system performance reliability timely and adequately, and provide an efficient and flexible software platform for performance reliability modeling and analyzing, a multi-model integrated performance reliability simulation environment called MISER was developed. It refers to several typical multi-model simulation systems and integrated simulation idea, supports simple object-oriented design and analyzing technique, provides multi-resolution modeling as well as multi-model integration, and uses reward variables and activity variables to define the well-known or customized reliability indexes. It provides some well-defined importance-sampling plan to improve sampling efficiency. At the same time, it also can be extended easily and supports user-defined models. At last, the application of MISER on some laser device＇s energy module was proposed.
