| Abstract | A method is developed for the optimal design of single
source, looped gravity fed water distribution systems
subjected to a s ingle loading pattern .This method is based
on a recent development in the field of looped water
distribution systems , so called linear programming gradient
(LPG) method ,due to the work of Aleprovits and Shamir ( 1) •
The LPG method has the following drawbacks: the final
solution depends much on the starting flow pattern , and the
solution does not necessarily terminate at a local minimum
point. Our new method strengthens the LPG method in the following aspects: to eliminate high cost flow patterns for the initial solution in a systematic manner, and to modify the stepsize calculation to arrive at a local optimum
solution. This new method is applied to the test problem in (2) and a local optimal solution of cost $408,114 is obtained, which is a considerable improvement compared to the solution of $443,031 obtained in (2).
