为了获得低风险的复杂装备设计方案，提出了基于可靠性的综合集成设计。可靠性应在全寿命周期进行分析和量化，并在设计过程中采取措施确保产品在使用环境中其性能具有适当裕量；在综合集成设计过程中重要的问题是要在产品的先进性、可靠性、稳健性之间找到平衡的优化设计，它是在设计过程中逐步孕育而产生的，不是事后分析和评估出来的。由于常常是在信息不完备条件下进行产品设计与决策，在传统依赖于试验结果和部分数值模拟的决策方法基础上引入不确定性与裕度的量化的概念，以提供一种有效性评估的工程分析方法。实践表明，这种设计方法具有广泛的工程应用前景。

To get low-risk design project of complex weapon equipment, the integrated design methodology based-on reliability is proposed. The product's reliability must be analyzed and quantified during the whole product life-cycle; and in the design phase, some measures must be taken to assure appropriate margin of the product during the service and mission environments.It is an important problem to find one balanceable optimal design amid advantage, reliability and robustness of the product, so that these characteristics are all brewed and produced during the design procedure, and not analyzed and evaluated afterwards. Due to product design and decision-making with incomplete information in general, the new methodology of quantification of margins and uncertainty (QMU) is introduced based on traditional decision-making methodology, which does depend on experiment results and partial numeric simulations, to provide an engineering analysis method of validity evaluation. Some practice suggested that this design methodology may have extensive engineering application future.
