信息物理系统资源能力建模

Resources Capabilities Modeling for Cyber-Physical Systems

信息物理系统是一种自知系统,系统中存在大量具有信息物理紧密融合特征的异构资源,这给资源管理带来了巨大的挑战。能力模型是消除异构带来高复杂性的最佳资源描述模型。本文通过分析信息物理系统中的资源特征,借鉴人们处理日常事务的思维方式,给出了资源能力的概念,提出了基于哈希表的"任务类型-能力"的资源能力描述方法和基于历史信息的资源能力计算公式,并建立了资源能力组合模型。最后,通过火灾监控信息物理系统的资源能力建模案例来说明了该资源能力建模方法。

Cyber-physical system is a self-aware system.There are lots of cyber-physical heterogeneous components interacting in the system.This introduces intractable challenges to managing the resources.However,capability model is an excellent method to eliminate the complexity which is leaded by heterogeneity.This paper analyzed the characteristics of the CPS resources,gave the concept of the CPS resources,proposed an hash table based ＂TaskType-Capability＂ resource capability description and historical information based capability computing method,built an resource combination model.At last,it gave a firefight CPS resources capability modeling case.
