According to actual requirements of testability concept in engineering applications,the connotation is expanded and perfected.Through building a generalized

information description model and describing the optimization process of testability concept from the view of whole system & whole life,the key technologies which are desiderated to breakthrough were further clarified.Then a research idea based on the model and

multi-objective tradeoffs was proposed,which will lay a foundation for constructing the testability concept applicable to total life cycle and different maintenance levels.

testability concept, information description model, testability analysis,

依据测试性方案在工程应用中的实际需求,对其内涵与要求进行了拓展和完善。通过建立测试性方案优化设计广义信息描述模型,从装备全系统全寿命的角度对装备测试性方案优化设计过程进行了详细阐述,进一步明确亟需突破的关键技术。在此基础上提出基于模型和多目标权衡的测试性方案优化设计研究思路,为构建适合于装备全寿命周期各阶段以及不同维修级别的测试性方案奠定基础。
