刚刚开始学auto mod,这道题目搞不明白,希望大家看看 题目是这样的,; j1 X2 Y5 N, X! j; Q' c5 u
  Create a new model containing three independent processes, each with one operator. In each process, loads first move into an infinite capacity waiting queue, then into a single-capacity processing queue.
: ]( I5 T8 T! e! y* G' E  Loads are processed by each operator for the following time:$ H2 }+ \3 ~- ^
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
% y- H4 E8 {! I  Worker_B does the job according to a triangular distribution with a min of 30 mins, most likely value of 60 mins, and a max of 90 mins.3 o; k* b3 g* T5 B% `; J. ~
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.4 _) |3 o+ E) y+ z& y
Send loads to each pocess at the same rate (an exponentially distributed inter-arrival time with a mean of 68 mins) to understand the difference in the processing times of the three workers.
; [3 n& ~) g, p
: A  r& X& S- i( W问题:4 O; u# C0 P& f+ ]* ~2 i) I
After running the model for 10,000 days, what was the average number of loads in each process?* M2 o0 u# V/ x. x- k2 y

不胜感激!

Then You need to add a L_Control to drive up the whole simulation. and a Run Control of 10000 days.0 j1 z! s; J/ i
