A Multi-step Approach for Optimal Design and Management of the C-Town Pipe Network Model

A novel approach is here proposed for the optimal design and management of the C-Town pipe network considering three objective functions (OFs) (1-installation cost, 2-operational cost and 3-cost of the pressure reducing valves). The approach is based on the following steps: i) identification of some feasible first attempt solutions; ii) application of the NSGAII to the 2D optimization problem with OFs 1 and 2; iii) application of the NSGAII with OFs 2 and 3; iv) derivation of the 3D Pareto surface by grouping the solutions found at the end of steps ii and iii and selection of a final solution.
