论文摘要
系统的复杂性在设计，评估和实施的实用和有用的网络物理系统中已变得无处不在。这种提高的复杂性影响了设计网络物理系统所需的模型的管理，这些模型能够考虑到许多````''''，以使它们安全且安全，并最终有弹性有弹性。我们提出了一个用于系统设计的本体论元模型，该元模型增加了已经存在的行业元模型，以捕获各种模型元素与安全，安全性和弹性考虑因素之间的关系。采用这种元模型会导致更具凝聚力和结构化的建模工作，并总体上提高了已经存在的模型的可伸缩性，可用性和统一。反过来，这导致了以任务为导向的观点，即设计安全防御和弹性机制，以应对不良行为。我们在开源GraphQL实现中说明了此元模型，该实现可以与多种建模语言进行连接。我们使用石油和天然气管道模型进行了详细的演示，支持我们提出的元模型。
System complexity has become ubiquitous in the design, assessment, and implementation of practical and useful cyber-physical systems. This increased complexity is impacting the management of models necessary for designing cyber-physical systems that are able to take into account a number of ``-ilities'', such that they are safe and secure and ultimately resilient to disruption of service. We propose an ontological metamodel for system design that augments an already existing industry metamodel to capture the relationships between various model elements and safety, security, and resilient considerations. Employing this metamodel leads to more cohesive and structured modeling efforts with an overall increase in scalability, usability, and unification of already existing models. In turn, this leads to a mission-oriented perspective in designing security defenses and resilience mechanisms to combat undesirable behaviors. We illustrate this metamodel in an open-source GraphQL implementation, which can interface with a number of modeling languages. We support our proposed metamodel with a detailed demonstration using an oil and gas pipeline model.
