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,
) Z2 U9 b  ]9 V0 F) I& s  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.
1 d1 x; f. i; m0 ~  Loads are processed by each operator for the following time:
! l! C$ f, ~0 y8 `( I, N8 i: K  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
' U( a2 o. q8 Y! W/ n+ w2 M7 }/ X  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.* ^* d4 B  U8 @, |) K# i: ~' `
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.( L* l" Z0 X* g
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.0 f, m/ e7 O9 ]; m% |

8 g& D$ u# r' ~$ c问题:: _: ~; d, _0 ]1 T( A+ Q
After running the model for 10,000 days, what was the average number of loads in each process?2 h' ^# J" b) x! \& \7 z4 g- Z

不胜感激!

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