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,: \8 \2 s8 u1 h: H- u/ }
  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." A$ u$ U) @8 u% T( }# I
  Loads are processed by each operator for the following time:4 m6 ]$ z1 \* p" a7 g
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.; C1 t# }6 B3 [% 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.
" b6 T6 D0 [+ g/ v  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.! |0 Z+ Z% u1 `
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 W- [; V, Z* S4 S6 A* f
3 o! {1 I0 m2 }5 L8 b. w3 g问题:: J0 ~5 r! Q6 L. ?5 X- K
After running the model for 10,000 days, what was the average number of loads in each process?

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.

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