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,
+ [! H! b* r) `: @; n  W  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.2 ]- p) w$ c1 {
  Loads are processed by each operator for the following time:, x& Z/ n3 n) x  L/ v
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.1 Y: S+ S7 g5 _5 J$ H, ?1 V
  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.+ h1 }1 l: v! A/ P2 q5 \
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
) w2 ]( R. P' `/ Z0 D" HSend 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.

问题:
# S4 Q  R( E& s$ X. K3 d5 ~. M) WAfter running the model for 10,000 days, what was the average number of loads in each process?

in P_C, you need to send to die.* U4 @$ p, P3 h8 t

; k2 y  ^! D: rThen You need to add a L_Control to drive up the whole simulation. and a Run Control of 10000 days.7 A5 a5 d+ Q5 A6 H

Remember to turn off the animation before you run your model.
