可追溯性管理依赖于支持模型，即可追溯性信息模型（TIM），该模型定义了存在哪些类型的关系之间存在哪些类型的关系，并且包含其他约束，例如多重性。构建适合目的的TIM对于确保可追溯性策略带来所需的好处至关重要。但是，哪些设计决策对于TIMS的构建至关重要，并且对可追溯性的有用性和适用性产生了影响仍然是一个悬而未决的问题。在本文中，我们使用了两种tims构建的tims，用于与工业安全专家一起为关键的安全系统，以确定关键的设计决策。我们还提出了基于系统文献审查的TIMS的比较方案，并根据该计划评估了两种情况以及文献中的TIM。基于我们的分析，我们得出了对TIM构建的关键见解以及确保TIM适合目的的设计决策。
Traceability management relies on a supporting model, the traceability information model (TIM), that defines which types of relationships exist between which artifacts and contains additional constraints such as multiplicities. Constructing a TIM that is fit for purpose is crucial to ensure that a traceability strategy yields the desired benefits. However, which design decisions are critical in the construction of TIMs and which impact they have on the usefulness and applicability of traceability is still an open question. In this paper, we use two cases of TIMs constructed for safety-critical, automotive systems with industrial safety experts, to identify key design decisions. We also propose a comparison scheme for TIMs based on a systematic literature review and evaluate the two cases as well as TIMs from the literature according to the scheme. Based on our analyses, we thus derive key insights into TIM construction and the design decisions that ensure that a TIM is fit for purpose.
