Multi-Criteria Decision-Making Approach for Design Evaluation and Optimization of Smart Pet Water Fountains

To address the challenges of homogenization and unclear functional hierarchy in pet water fountain design, as well as to meet diverse user needs, reduce costs, and improve efficiency, this study undertakes product design based on comprehensive research and analysis of key design elements that fulfill the practical requirements of both humans and pets. Furthermore, to evaluate and optimize the proposed design scheme, an integrated AHP-improved CRITIC-TOPSIS comprehensive design evaluation model is introduced within the framework of multi-criteria decision theory to assess and refine pet water fountain design solutions. The methodology commences with the application of the AHP to construct a multi-level evaluation index system and determine subjective weights for each index. Subsequently, the improved CRITIC method is integrated to calculate the comprehensive weights of each indicator. The TOPSIS method is then employed to rank and optimize the design schemes. Strategies for further improvement are proposed based on key indicators that are assigned higher weights. The results of the simulation verification experiment and sensitivity analysis indicate that the proposed method achieves high accuracy and reliability in the evaluation of pet water fountain designs. This methodology establishes a rigorous evaluation framework that can be extended to other pet product designs.
