Table 6: System function comparison analysis. design must be slightly adjusted but will not affect the operations of the whole system. The verification results showed that the human-machine interface of our proposed agents can meet important design preferences and provide approximately optimal balance. Finally, the system effectiveness experiment aimed to analyze the actual operation and experience satisfaction of the proposed system APPs. The three aforementioned groups were used as a reference frame for analysis, as shown in Table 10. The satisfaction scale was 1-5 points, representing strongly dissatisfied (1 point) to most satisfied (5 points). It was observed that unrelated departments care more about the interface appearance and the operation of this system being more convenient. The effect was significant in the middle/high age-bracket. Related departments indicated that operation and fluency are somewhat insufficient and should be enhanced. An important indicator was that information correctness was graded as being high. According to this table, fluency is somewhat insufficient, but the graphical menu design of the system APP is easy for the users of the middle/high age-bracket to operate, which is an obvious outcome. \begin{table}
