摘要: Water supply (WS) tariffs have evolved significantly in the past decades, although a varying fashion around world. Indeed, this development is linked to increasingly demanding requirements, or objectives that be achieved by water utilities (e.g., stricter quality standards and infrastructure maintenance levels, cost recovery, social concerns environmental protection demands). The perception of WS as powerful management tool, subject context dependent objectives, raises concern on how prioritize them. This hierarchy desirable due possible conflicting nature objectives. From point view, basis protecting public interest, fitness between set actual needs may require broader institutional approach. need for regulatory activity required too much arbitrariness tariff setting procedures. For objective, tool set, based multicriteria decision analysis (MCDA) modeling methods, provide requisite framework capable considering multiple dimensions assessment specialists, practitioners other legitimate stakeholders ‘tariff setting’ making process. specified suitability (TSF) will work taking into account utilities’ particular background factors. outcomes allow determine build tailored policy recommendations, which are critical aspects sound regulation.
