A general multi-objective hyper-heuristic for water distribution network design with discolouration risk

<12> This work is one of the first papers to explore the use of hyper-heuristics in water distribution network (WDN) optimisation. The paper describes a new multi-objective hyperheuristic known as the Markov-chain hyper-heuristic (MCHH) that shows significant improvements against well-established metaheuristic optimisation techniques, NSGAII and SPEA2. The method explores the trade-off between hydraulic performance and the risk of discolouration of water, a difficult problem affecting all UK water companies. The work on MCHH formed the basis of a successful EPSRC funding application (EP/K000519/1) which has UK industry involvement. This journal has a 5-year impact factor of 1.46.
