| Abstract | We clarify the property, in the study of optimization models for
the design of water distribution network systems, that at the optimal
solution each link consists of at most two pipe segments with
adjacent diameters in the commercially available list of candidate
diameters. We extend the result by Fujiwara (1986) and more general
case has been considered to find the optimal combination of pipe
diameters for any link in any network (branched or looped). It has
been shown that the optimal solution for any link completely depends
only on the shape of cost of unit length of commercially available
pipe sizes versus hydraulic gradient curve.
A new solution procedure, called "Lagrange multipliers method",
and an 1inear programming based heuristic method have been proposed to
determine the optimal pipe sizes, assuming pipe diameters as
continuous variables for a special type of branched network. This
heuristic was found to be much more efficient than linear programming
method from the computational point of view. |
