Knowledge Management For Fault‐Tolerant Water Distribution
Jing Lin, Ali R. Hurson, Sahra Sedigh · 2013
This chapter presents and validates environmental decision support systems (EDSSs) where ontologies are utilized to classify failure events and determine appropriate countermeasures to mitigate their effects. It provides an overview of previous related work in EDSSs, agent-based modeling and simulation techniques, knowledge representation capabilities of ontology, and simulation techniques as tools for validation of models for cyber-physical system (CPS). The chapter discusses the major functional components of a generic CPS, the major components of the derivative water distribution network (WDN), and the agent-based model for WDN operation. It also provides a detailed introduction to the class composition of the ontology-based framework. The chapter illustrates the automated failure classification and mitigation. It outlines the object properties for behavior reasoning and the data properties for value reasoning, respectively. Finally, the chapter demonstrates the benefits of the ontology-based framework through a test case on an integrated CPS simulator for WDN.
