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,1 H9 Y, m8 p* H2 U& \8 c, ^
  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.% v- v+ }, m" j  X& R8 Q
  Loads are processed by each operator for the following time:. ?1 p3 c8 {( I( @; p2 h
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
+ r% ^5 z( ]6 Q7 f5 V. B  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.
9 |( ^6 C3 L% E, n. {! f7 q, k  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.) B' }( N; `; V& ?& i
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.- e; V$ A; U* r. I' Y  ^7 {
/ A0 x3 W$ s7 W8 |" H2 f, U
问题:: R! I. N" d6 l# T
After running the model for 10,000 days, what was the average number of loads in each process?5 R3 ]! `% Q4 A8 t+ k% W3 W' k* ^
" Y) T% P& R3 }1 m6 w6 U: _' m
不胜感激!

in P_C, you need to send to die.

Then You need to add a L_Control to drive up the whole simulation. and a Run Control of 10000 days.

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