The text states: “The tutoring system (A5) based on deep learning has consistently ranked second, and the simulation-based tutoring system (A4) placed second in all scenarios tested.”
This is impossible and contradicts Tables 5–8, where A5 is ranked first and A4 second. Please correct this paragraph.
C10 “Cost-effectiveness” is treated as a cost criterion and minimized. Section “Best and Worst Criterion Values” says C10 is the only cost criterion and that “the minimum defuzzified value of C10 is considered the best.” But Table 1 defines C10 as “Cost-effectiveness — Financial feasibility”, which is normally a benefit criterion to be maximized. If C10 is truly cost-effectiveness, the ideal should be the maximum, and the VIKOR ranking may change. Please clarify whether C10 is “cost” or “cost-effectiveness,” and recompute if necessary.
