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,3 \+ k! \( J7 l$ V+ u. C) L. G& 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.
: O3 H, I; R8 c& L  Loads are processed by each operator for the following time:
) _# d& T& V7 m. Y  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
' V! @3 W0 n! \3 ^. 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.. j: n1 }; h4 i6 |
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.- L3 v7 E8 R+ F" S8 `
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.; @' O. o8 l- f# U, V! y9 S+ y( G
) W5 @% ~3 X8 g/ r8 ~# o$ h
问题:9 e+ Z) [+ m4 @& M) C- K
After running the model for 10,000 days, what was the average number of loads in each process?

in P_C, you need to send to die.1 o, J; G5 |+ K: m

Then You need to add a L_Control to drive up the whole simulation. and a Run Control of 10000 days.
