Use of Honey-Bee Mating Optimization Algorithm to Design Water Distribution Network in Gurudeniya Service Zone, Gurudeniya, Sri Lanka (2110.10886v2)

Abstract: Water distribution network (WDN) is a highly complex urban infrastructure that is intended to supply water from source node to consumer nodes. As far as the components of an infrastructure are concerned, the interconnecting pipes that transport water from source node to the demand nodes account for the major fraction of the capital cost. Therefore, when designing WDN, the primary concern is on finding the optimal combination of pipe diameters that satisfies the hydraulic-head requirements at minimum cost. More recent methodologies employ direct heuristic and stochastic heuristic algorithms for the design of WDN. In this study, the use of Honey-Bee Mating Optimization (HBMO) stochastic algorithm for the design of WDN in the Gurudeniya Service Zone, Gurudeniya, Sri Lanka, has been examined. In-built hydraulic constraints have enabled the algorithm to deliver results without needing a separate hydraulic simulation software in this design. The solutions given by HBMO algorithm and the solution implemented by National Water Supply and Drainage Board, Sri Lanka have been compared. From the implementation of the HBMO algorithm, results show that the HBMO algorithm is successful in addressing the WDN design problem with given hydraulic constraints for Gurudeniya Service Zone.
