The Thai durian industry is one of most important agricultural exports of the country, evidenced by its rapid growth and expanding demand in international markets. De-velopment of more advanced inspection technologies is therefore crucial for the in-dustry to ensure competitiveness toward global standards. This research aimed to de-velop an integrated decision support system (DSS) for selecting appropriate non-destructive testing (NDT) technologies for durian quality inspection. The study integrated Multi-Criteria Decision Analysis (MCDA), Analytic Hierarchy Process (AHP), Technique for Order Preference by Similarity to Ideal Solution (TOPSIS), and Techno-Economic Analysis (TEA) to evaluate five NDT technologies, including Near-Infrared Spectroscopy (NIR), Hyperspectral Imaging (HSI), Acoustic Response Analysis (RSA), Electrical Impedance Spectroscopy (EIS), and X-ray Imaging. The evaluation criteria consisted of three dimensions: technical performance, economic viability, and operational feasibility.
Results revealed that Near-Infrared Spectroscopy (NIR) has the highest suitability for large-scale industrial implementation, achieving the highest weighted score (4.57) and ranked first in the TOPSIS analysis with a Closeness Coefficient of 0.91. The findings suggested that selection of NDT technologies must balance technical accuracy with economic and operational viability. The proposed DSS framework can support the de-velopment of smart agro-industry systems and contribute to the sustainable advance-ment of Thailand’s durian export sector.
