Scheme processes about complicated engineering systems are certainly complex on account of the interdependencies among submodules in the same tier and between tiers of a segmented hierarchy. In the design process with decision mode, this effects in communications among groups of design decisions. It is important to extract and represent the knowledge relevant to the decision communications for developing design process with decision mode. There are two critical issues addressed regarding the modeling of communications: decision types and these are made in various tiers. To stress the above two issues, there are several fundamental communication models defined among decisions in this study. Meanwhile, a presented ontology to identify the knowledge connected with these communication models. Critical benefits of the ontology involve that a hierarchical communications between decisions can be extracted, and a decision task-flows with accessible, adaptable, and implementable features for developing more complex systems can be generated. The applicability of the ontology is shown by scheme for an automotive braking troubleshooting service example.

复杂工程系统的方案过程当然是复杂的，因为同一层的子模块之间以及分段层次结构的层之间的相互依赖。在具有决策模式的设计过程中，这会影响设计决策组之间的通信。提取和表示与决策通信相关的知识对于开发具有决策模式的设计过程非常重要。关于通信建模，有两个关键问题需要解决：决策类型，这些是在不同层级制定的。为了强调上述两个问题，本研究中的决策定义了几个基本的沟通模型。同时，提出本体来识别与这些通信模型相关的知识。本体的关键好处包括可以提取决策之间的分层通信，并且可以生成具有可访问、适应性和可实现特征的决策任务流，以开发更复杂的系统。以汽车制动故障排除服务为例，通过方案展示了本体的适用性。
