The research population comprised hotel operators, tour companies, restaurant businesses, and other service-related enterprises across Thailand. A sample of 500 respondents was selected using questionnaires as the primary data collection tool. The data were analyzed using multivariate statistical techniques to construct the SEM. The results revealed that the proposed model demonstrated a good fit with the empirical data, as indicated by statistical values: p-value = 0.078, CMIN/DF = 1.269, GFI = 0.980, and RMSEA = 0.023, all meeting the recommended thresholds and showing significance at the 0.001 level. Analysis of the overall model influence indicated that technology management exerted the strongest direct effect on service quality, with a standardized regression weight of 0.79. This finding provides empirical evidence that modern technology management significantly enhances the efficiency and effectiveness of service delivery for elderly tourism, thereby increasing customer satisfaction and industry recognition.101020251010202522532261177https://wseas.com/journals/bae/2025/d585107-3415.pdf10.37394/23207.2025.22.177https://wseas.com/journals/bae/2025/d585107-3415.pdfBank of Ayudhya public company limited.
