RESUMO:

^{The benefits provided by a model of system dynamics are directly related to its correct construction. One of the main challenges in the process of building such models is that they must be able to effectively represent a specific problematic situation. For the process of structuring the problem of managing water supply systems, this requires efforts to understand "divergent solutions", for involves a complex and interrelated structure of several specialists involved with different views and proposed solutions, which may be conflicting. In light of the above discussion, this study has as its main objective to develop a multi-methodological approach, combining the Strategic Options Development and Analysis (SODA) problem structuring method with the System Dynamics (SD) model. The role of each of these clearly represents the contribution of this study: SODA in the phase of structuring the problem (construction of alternatives to solve such a problem) and SD in the phase of evaluating these alternatives. The developed multi-methodological approach will be used to create and simulate scenarios considering management strategies, and the various variables that affect a water supply system, including population growth, in order to assess more "assertive" water management strategies than could have been adopted to face the water crisis (2012-2017) and analyze future scenarios.The results show that, based on the view of specialists with considerable experience for the case studied, it was possible to structure the problem and, therefore, propose a set of strategies (alternatives), which were: water loss control, wastewater reuse, application of more efficient tariffs to reduce water waste, inter-basin water transfer, and awareness regarding the use of water resources. After the survey of alternatives, scenarios were simulated considering these strategies. Analyzing these scenarios, it was found that despite of the management options claims to be effective solutions in a short term water scarcity, (for example the influence of the scarcity-based tariff on the reduction of water uses), these strategies would no longer be sufficient in a context of severe droughts and in a water production system that it is highly dependent on rainfall, as is the case in the semi-arid region of Paraíba. On the other hand, policies involving the management of water supply, e.g., wastewater reuse and inter-basin water transfers, here considering the PISF, are quite effective in maintaining the water supply and avoiding a water collapse in the region. Furthermore, employing the Monte Carlo approach in simulating the system dynamics proved that water supply is sensitive to tariffs based on scarcity, wastewater reuse and water transfer between basins. It is expected that the development of this multi-methodological approach will be useful to support managers in decision making and implementation of water management strategies.}
