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,
! k8 V% D# ?8 z  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.
/ Q+ p9 j/ J' i( s' m  Loads are processed by each operator for the following time:0 r) `5 f/ @4 C- y0 |. u
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.3 T& a' K; W& `$ y. s
  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.
4 \. e( y2 {5 C- E3 d: z5 j+ n  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.3 A4 e8 w' s- N7 J7 X; Z- n
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.
5 X# {1 [6 D6 }. e; p5 A, I+ q& e: F
问题:0 ^& |/ |$ m) l, x! p1 s! U* A
After running the model for 10,000 days, what was the average number of loads in each process?" B5 K8 S( j1 q2 ^- K) i

不胜感激!

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