| Abstract | Global urbanization and increasing water demand make efficient water resource management crucial. This study employs Multi-Criteria Decision Making (MCDM) to evaluate smart city water management strategies. We use representative criteria, employ objective judgment, assign weights through the Analytic Hierarchy Process (AHP), and score strategies based on meeting these criteria. We find that the "Effectiveness and Risk Management" criterion carries the highest weight (15.28%), underscoring its pivotal role in strategy evaluation and robustness. Medium-weight criteria include "Resource Efficiency, Equity, and Social Considerations" (10.44%), "Integration with Existing Systems, Technological Feasibility, and Ease of Implementation" (10.10%), and "Environmental Impact" (9.84%) for ecological mitigation. "Community Engagement and Public Acceptance" (9.79%) recognizes involvement, while "Scalability and Adaptability" (9.35%) addresses changing conditions. "Return on Investment" (9.07%) and "Regulatory and Policy Alignment" (8.8%) balance financial and governance concerns. Two low-weight criteria, "Data Reliability" (8.78%) and "Long-Term Sustainability" (8.55%), stress data accuracy and sustainability. Highly weighted strategies like "Smart Metering and Monitoring, Demand Management, Behavior Change" and "Smart Irrigation Systems" are particularly effective in improving water management in smart cities. However, medium-weighted (e.g., "Educational Campaigns and Public Awareness", "Policy and Regulation", "Rainwater Harvesting", "Offshore Floating Photovoltaic Systems", "Collaboration and Partnerships", "Graywater Recycling and Reuse", and "Distributed Water Infrastructure") and low-weighted (e.g., "Water Desalination") strategies also contribute and can be combined with higher-ranked ones to create customized water management approaches for each smart city's unique context. This research is significant because it addresses urban water resource management complexity, offers a multi-criteria approach to enhance traditional single-focused methods, evaluates water strategies in smart cities comprehensively, and provides a criteria-weight-based resource allocation framework for sustainable decisions, boosting smart city resilience. Note that results may vary based on specific smart city needs and constraints. Future studies could explore factors like climate change on water management in smart cities and consider alternative MCDM methods like TOPSIS or ELECTRE for strategy evaluation. |
