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 {+ l' ~- @* ]6 E  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./ |# w9 m! ?% r
  Loads are processed by each operator for the following time:
4 T9 R+ z0 _6 n4 k3 o  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.$ f( Z* q, Y( l
  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.( m# N" V% t( ]# ]
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.6 z$ ]0 C1 i, t$ d& o; f
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.6 N# Z7 {3 v, b7 D

! \+ V; N% B) r. Z  ]7 P3 s问题:1 G; n6 v$ p. b( F- x
After running the model for 10,000 days, what was the average number of loads in each process?% `2 w+ K* m$ X; G2 s6 L: z5 x6 B8 j

9 E* e7 T" g3 L不胜感激!

( B2 I* |) y. pin 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.
