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 V+ ^1 I8 {: I+ N9 M
  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 d! R0 L7 o' o% j9 Y  Loads are processed by each operator for the following time:
& P* s2 N8 G6 r$ X  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.6 j) q/ s# b: `; ]7 n) D' 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.
! P0 E% L! P0 D( @  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
  K4 s5 A8 `9 G% G- BSend 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.. v4 e: Z8 i6 L

, A) b! H* t9 z. t5 u# ]5 M/ ^6 L问题:) _' t3 ~( d: }% k
After running the model for 10,000 days, what was the average number of loads in each process?2 i% V' r# S! I* v) S" Y

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.% W: C  v, F: \

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