Combining MCDM Methods and AHP to Improve TTQS: A Case Study of the VETC

This study proposed the use of the benchmarking framework to evaluate the performance of vocational education and training centers (VETC) in using the Taiwan Training Quality System (TTQS) to ensure the advantages and disadvantages of each factor and to confirm the priority of the weights of the criteria and alternative solutions. This study used the Delphi method, Analytic Hierarchy Process Theory (AHP), and Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) as the base method and divided the whole process into three stages. In the first stage, the Delphi method identified and integrated the criteria, sub-criteria, and alternatives. In the second stage, AHP was used to ensure that VETC underwent performance evaluation against their competitors through TTQS to observe the relationships of every criteria and sub-criteria, as well as the overall performance indicators. In the third stage, the TOPSIS is used as the basis to evaluate the VETC performance.
