Resource sharing in cyber-physical systems: modelling framework and case studies
提出一个基于资源共享的框架（RSBF），结合图论与社会福祉函数建模信息物理系统，通过智能工厂调度、智能电网能源分配和多机器人系统信息路由三个案例验证，在基准调度问题上以较少计算时间获得接近最优的结果。
Cyber-physical systems (CPSs) have attracted significant research interest because of their promising applications across different domains; nonetheless, how to effectively model CPSs in real applications is still a challenge. In this article, a resource sharing-based framework (RSBF) for CPSs is developed to enable flexible modelling of a wide range of CPSs and systems of CPSs, with specific focus on resource sharing. RSBF combines elements from graph theory and social welfare to describe complex arrangements of overlapping task and resource communities in CPSs, with the objective of maximising CPS utility through decentralised control. The framework implementation is validated through three case studies: scheduling in smart factories, energy distribution in smart grids and information routing in multi-robot systems. Results show that RSBF can successfully represent the dissimilar systems under study. Furthermore, performance analysis on benchmark scheduling problems yields near-optimal results with less computational time, showing the potential of the use of social welfare functions to CPS modelling and control.
