[0049] Examples:
[0050] The invention uses MATLAB to compile executable programs according to the content of the invention. The effect is illustrated by an example of a passenger car assembly line of a certain car company. Select the tightening equipment of a tightening station, and continuously collect the start time point and end time point of each operation by the operator within a longer total sample time. The shortest working time in a day is counted as the working time data of the day for complexity measurement. Table 2 shows the fastest working time of the manual station operator in a relatively long period of time.

[0054] The specific parameters of the fitted curve model are as follows:
[0055] a=89s
[0056] b=-0.2
[0057] t(x) is the shortest operating time used by the operator on the xth day of the station, a is the shortest operating time of the operator on the first day in this period o...
