Reliability testability collaborative modeling and optimization design method based on availability model

The invention belongs to the field of reliability design analysis. The invention provides an equipment reliability testability collaborative modeling and optimization design method based on an availability model, and the method comprises the steps: taking a key design index in a reliability and testability design scheme as decision attribute data for judging whether the reliability and testability design scheme is good or not, and determining a weight coefficient of each decision attribute data; according to the reliability and testability design scheme optimization model based on multi-attribute decision making, optimization analysis of multiple reliability and testability design schemes is achieved, a sorting result of the multiple design schemes is obtained, finally, the optimal reliability and testability design scheme is selected, and therefore the overall reliability and testability collaborative modeling and optimization technology is achieved. 本发明属于可靠性设计分析领域。提出一种基于可用性模型的装备可靠性测试性协同建模与优化设计方法，将可靠性与测试性设计方
