Review of applications of SIMDEUM, a stochastic drinking water demand model with small temporal and spatial scale

摘要

Many researchers have developed drinking water demand models with various temporal and spatial scales. A limited number of models are available at a temporal scale of one second and a spatial scale of a single home. Reasons forudbuilding these models were described in the papers in which the models were introduced, along with a discussion onudpotential applications. However, the predicted applications are seldom re-examined. As SIMDEUM, a stochastic end-useudmodel for drinking water demand, has often been applied in research and practice since it was developed, we are reexaminingudits applications in this paper. SIMDEUM’s original purpose was to calculate maximum demands in order to be able to design self-cleaning networks. Yet, the model has been useful in many more applications. This paper gives anudoverview of the many fields of application of SIMDEUM and shows where this type of demand model is indispensable andudwhere it has limited practical value. This overview also leads to an understanding of requirements on demand models inudvarious applications.
