Research on the Risk Entropy Model of Water Supply Systems Based on Entropy Theory

Abstract:

According to the uncertainty characteristics of water supply systems when it suffered by the threats, the entropy function was introduced into water supply systems for the risk assessment studies, and the risk entropy model of water supply systems was proposed. Taking the earthquake disaster as an example, firstly, based on the risk assessment theory and information entropy theory, the severity factor E_j of earthquake X_j which the water supply systems would be suffered was defined. Secondly, the product of severity factor E_j and occurrence probability P_j of earthquake X_j was computed, and the normalized value of the product was defined as the interaction coefficient q_j of earthquake X_j. Then, based on the theory basis above and risk formula, the risk entropy model H(R) of water supply systems was established. Finally, a water supply systems of north china was taking as a case studies. Through application we found that the model was theoretical and practical feasibility, which can be used to solve the uncertainty problem of water supply systems.
