Abstract

As global population aging intensifies, constructing a scientific evaluation system for Integrated Medical and Elderly Care service quality has emerged as a vital strategy. To address the inherent fuzziness in evaluations and the risk preferences of decision-makers, this paper proposes a multi-criteria group decision-making approach integrating Triangular Intuitionistic Fuzzy Numbers and Cumulative Prospect Theory. First, an evaluation criteria system is established across five core dimensions: life care, cultural and recreational service, medical nursing, rehabilitation and health care, and spiritual comfort. Second, the Bidirectional Projection method is utilized to transform TIFN evaluation data into connection degrees, which are then aggregated using the Connection Degree Weighted Averaging operator. Subsequently, CPT is introduced to characterize the behavioral features of decision-makers regarding gains and losses, facilitating the calculation of overall prospect values. Empirical results indicate that medical nursing and rehabilitation are the decisive dimensions for service quality, with Institution A2 identified as the optimal choice due to its superior performance in these areas. This study provides a rigorous decision-making framework for quality supervision and resource optimization in IMEC institutions.
