“…A relatively simple WDS, first presented by Stokes et al (2014a), is chosen as the case study because it enables the complexity of design and pump operational management trade-offs to be analyzed, while still incorporating the fundamental complexity of a loop network and pumped WDS with integrated water storage. Example input files for this case study are provided as supplemental material.…”

“…Objectives of pumping electricity cost and GHG emissions are considered separately and the characteristics of the optimal operating strategies for the objectives are compared. Multi-objective optimization of cost and GHG emissions for WDSs has been extensively covered in Wu et al (2010a); Wu et al (2010b); Wu et al (2011); Stokes et al (2012b); Stokes et al (2012c); Wu et al (2012a); Wu et al (2012b); Wu et al, (2013);and Stokes et al (2014). This research is different in that it considers the effect of the different pump operating regimes on each objective individually.…”

“…Operational policies are also subject to several constraints, including acceptable levels of water in storage tanks, maximum pumped volumes, long term tank level balancing, nodal pressure limits and maximum pipe velocities. Previous studies have usually been restricted to using either trigger levels (Paschke et al 2001;Stokes et al 2012b) or scheduling (Mackle et al 1995;Goryashko and Nemisrovski 2014) and have not considered more complex operations such as trigger levels that vary throughout the day or combinations of trigger levels and scheduling. Lower and upper trigger levels represent the tank levels at which the pump(s) will turn on or off respectively (when pumping to a downstream tank).…”

A single-objective optimization model has been developed for water distribution system (WDS) pumping operations, considering five different types of pump operating regimes. These regimes use tank trigger levels, scheduling and a combination of both to control pumps. A new toolkit development to alter rule-based controls in EPANET has allowed more complex pump operating regimes than have previously been considered to be optimized. The performance of each of the regimes is compared with respect to two different objectives; cost and greenhouse gas (GHG) emissions, which were optimized separately to allow the comparison of regimes to be made more clearly. Two case study networks, including one that represents a segment of the South Australian WDS, illustrate the effectiveness of the model. Time-based scheduling operating strategies were found to perform better than the other types of pump operating regimes.Significant cost savings were achieved for the South Australian case study network compared to its current operation.

Abstract:Dealing with real world engineering problems, often comes with facing multiple and conflicting objectives and requirements. Water distributions systems (WDS) are not exempt from this: while cost and hydraulic performance are usually conflicting objectives, several requirements related with environmental issues in water sources might be in conflict as well. Commonly, optimisation statements are defined in order to address the WDS design, management and/or control. Multi-objective optimisation can handle such conflicting objectives, by means of a simultaneous optimisation of the design objectives, in order to approximate the so-called Pareto front. In such algorithms it is possible to embed preference handling mechanisms, with the aim of improving the pertinency of the approximation. In this paper we propose two mechanisms to handle such preferences based on the TOPSIS (Technique for Order of Preference by Similarity to Ideal Solution) and PROMETHEE (Preference Ranking Organisation METHod for Enrichment of Evaluations) methods. Performance evaluation on two benchmarks validates the usefulness of such approaches according to the degree of flexibility to capture designers' preferences.
