“…In the water resources area, the technique has been used for optimal choice of sewerage treatment process for a high capacity but limited area site in Hong Kong (Tang and Ellis, 1991), catchment management (de Steiguer et al, 2003;Heathcote, 1998) and has been used in conjunction with other methods such as social choice theory (Srdjevic, 2007). However, Triantaphyllou (2001) reports some inconsistent behaviour in additive version of AHP.…”

Abstract. In the early days of Systems Analysis the focus was on providing tools for optimisation, modelling and simulation for use by experts. Now there is a recognition of the need to develop and disseminate tools to assist in making decisions, negotiating compromises and communicating preferences that can easily be used by stakeholders without the need for specialist training. The Water Framework Directive (WFD) requires public participation and thus provides a strong incentive for progress in this direction. This paper places the new paradigm in the context of the classical one and discusses some of the new approaches which can be used in the implementation of the WFD. These include multicriteria decision support methods suitable for environmental problems, adaptive management, cognitive mapping, social learning and cooperative design and group decision-making. Concordance methods (such as ELECTRE) and the Analytical Hierarchy Process (AHP) are identified as multi-criteria methods that can be readily integrated into Decision Support Systems (DSS) that deal with complex environmental issues with very many criteria, some of which are qualitative. The expanding use of the new paradigm provides an opportunity to observe and learn from the interaction of stakeholders with the new technology and to assess its effectiveness.

“…In most water resources planning and management problems, however, the number of decision-makers is likely to be larger resulting in an heterogenous group in which a consensus on a weight vector will not easily emerge. In that case, one option might be to construct a separate hierarchy of the decision-makers but this issue is still under discussion in the literature (Srdjevic, 2007;Ramanathan, 2001;Honert and Lootsma, 1996). …”

“…In SDP release decisions are made to maximize (minimize) current benefits (costs) plus the expected benefits (costs) from future operation, which are represented by the recursively calculated cost-to-go function F * . In reservoir operation studies, the most common state variables are the volume of water in the reservoirs and a description of current hydrologic conditions (Tejada-Guibert et al, 1995). Let n be the number of stages remaining until the end of the planning horizon, r t be the release during period t, a t the inflow during period t, s t the storage at the beginning of time period t, E the expectation operator, α the discount factor, and g t the system operational benefit during period t.…”

Abstract.Integrated Water Resources Management (IWRM) recommends, among other things, that the management of water resources systems be carried out at the lowest appropriate level in order to increase the transparency, acceptability and efficiency of the decision-making process. Empowering water users and stakeholders transforms the decision-making process by enlarging the number of point of views that must be considered as well as the set of rules through which decisions are taken. This paper investigates the impact of different group decision-making approaches on the operating policies of a water resource. To achieve this, the water resource allocation problem is formulated as an optimization problem which seeks to maximize the aggregated satisfaction of various water users corresponding to different approaches to collective choice, namely the utilitarian and the egalitarian ones. The optimal operating policies are then used in simulation and compared. The concepts are illustrated with a multipurpose reservoir in Chile. The analysis of simulation results reveals that if this reservoir were to be managed by its water users, both approaches to collective choice would yield significantly different operating policies. The paper concludes that the transfer of management to water users must be carefully implemented if a reasonable trade-off between equity and efficiency is to be achieved.

“…Use is made of a specific scale for these comparisons in terms of preference or importance. We use here the scale developed by Saaty [24], with the possibility of including intermediate numerical (decimal) values in the scale to model hesitation between two adjacent judgments [27].…”

Abstract. Decision making (DM) processes are becoming increasingly complex. The reasons are manifold. DM usually involves many aspects; some are purely technical, while others are subjective and derived from social, political, and environmental factors, among others. As a result, they involve items that are not easily comparable under the same units of measurement. Problems are made even more complex by the fact that current governance processes tend to involve all the stakeholders in the DM process.In this paper we consider the AHP methodology (analytic hierarchy process), which is used to build consistent aggregate results from data provided by decision makers. As some of the actors involved may not be completely familiar with all the criteria under consideration, it is common that the body of opinion, expressed in terms of pairwise comparison, is incomplete. To overcome this weakness, we propose a framework that enables users to provide data on their preferences in a partial and/or incomplete way and at different times. This article is an advance towards a dynamic model of AHP. The authors have addressed the problem of adding a new criterion or deleting obsolete criteria. Here, we address the consistent completion of a reciprocal matrix as a mechanism to obtain a consistent body of opinion issued in an incomplete manner by a specific actor. This feature is incorporated into a process of linearization previously introduced by the authors, which is concisely presented. Finally, we provide an application for leakage control in a water supply company. The adoption of suitable control leakage policies in water supply is a problem of enormous interest in the water industry, particularly in urban hydraulics.
