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,0 Q. k' N: V: ?# A( c# h6 e+ G
  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.
0 q: w: r* k9 u. m$ M! \3 V  Loads are processed by each operator for the following time:. A4 U9 u# ?' ^) m
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
: H) ^; l9 k: }* b! a2 U  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.0 U: A, H$ r( \2 R* p
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.; H6 d+ g* @* R8 `& j+ `. E
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.
+ o) P1 q) s2 j' o$ b
% D" {2 f6 B3 q% K问题:
$ T: [2 m& |, DAfter running the model for 10,000 days, what was the average number of loads in each process?' O$ A7 y# e% k5 @6 M
& ]5 z2 F* U, |: |6 d# S4 n1 G
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.& b( w$ j+ H2 j7 u1 a# s

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