摘要

Optimization of water supply looped networks has attracted a great deal of attention fromnresearchers for more than 30 years. As the classical water supply looped network optimizationnproblem is mathematically non-convex and multimodal, the resulting solution of most approachesnis uncertain in the sense of how close it is to the ‘‘best’’ solution. In many cases, this ‘‘best’’’ orn‘‘global’’ solution is invoked and pursued only intuitively without a clear understanding of itsnmeaning. This paper discusses what is involved in ‘‘global’’ solutions and the role that pipe flowndistribution can play to deal with non-convexity and multimodality in a new context. The authornhas introduced this new context recently after formulating a new objective function capable ofnfinding a looped network that can be economically more attractive than its related branched one.nTherefore, the convenience of an approach dealing with flows and heads, as relevant decisionnvariables, is encouraged in this paper and its advantages enumerated under the new concepts.nThe entropy approach is studied critically and an example is provided for comparison with thenproposed approach.
