Cyber-Physical Systems: a multi-criteria assessment for Internet-of-Things (IoT) systems

This article addresses a multi-criteria decision problem regarding the more suitable device (system) to perform a task for cyber-physical systems. New embedded systems provided everyday makes engineers’ decision very difficult. Components are proposed to formally describe solutions, criteria, constraints and priorities, taking into account users’ specific aspects. To materialise all formal descriptions, a model-driven approach is followed, allowing the design of enablers for interoperability with standards. It is enabled the use of different software languages and decision methods. Proposed framework enables a better Internet-of-Things system selection, and therefore stakeholders can perform a more suitable design of their cyber-physical enterprise systems.

本文针对信息物理系统（Cyber-Physical Systems）中适配任务执行的更优设备（系统）多准则决策问题展开研究。每日涌现的新型嵌入式系统大幅提升了工程师的决策难度。本文提出可形式化描述解决方案、准则、约束与优先级的组件，并充分考量用户的个性化需求。为实现所有形式化描述内容，本文采用模型驱动方法，可设计出适配标准互操作性的支撑模块，支持使用多种软件语言与决策方法。所提出的框架可实现更优质的物联网（Internet of Things）系统选型，进而帮助利益相关方更合理地设计其信息物理企业系统。
