Test and qualification (T&Q) phases take a significant portion of the time to market for critical products in the space industry, especially when introducing new technologies. Since T&Q are treated as standard procedures, they tend to be independent of the architectural design phases and kept away from design decisions. However, when introducing new technologies, qualification procedures may differ from those established in regular design scenarios, and the estimation of qualification costs and duration is problematic. There is a lack of design for qualification methods capable of modelling these activities in early phases and use those models to support the architecture design of products with affordable test and qualification phases. In this article, a computer-assisted, model-based design method to model T&Q activities concerning early product architecture designs is proposed. Product architecture alternatives, test schedules and cost are connected through the quantification of T&Q drivers and driver rates. The design method is demonstrated using a case study about electric propulsion for satellites. The method is applicable for design situations where the choice of technology has a strong dependence on the qualification procedure.

测试和认证 (T&Q) 阶段占用了航天工业关键产品的大部分上市时间，尤其是在引入新技术时。由于 T&Q 被视为标准程序，因此它们往往独立于架构设计阶段并远离设计决策。然而，在引入新技术时，认证程序可能与常规设计场景中建立的程序不同，并且认证成本和持续时间的估算存在问题。缺乏能够在早期阶段对这些活动进行建模并使用这些模型来支持具有负担得起的测试和认证阶段的产品架构设计的认证方法设计。在本文中，一种计算机辅助的、基于模型的设计方法来模拟 T& 提出了有关早期产品架构​​设计的 Q 活动。产品架构备选方案、测试计划和成本通过 T&Q 驱动程序和驱动程序费率的量化联系起来。该设计方法通过一个关于卫星电力推进的案例研究来演示。该方法适用于技术选择对鉴定程序有很强依赖性的设计情况。
