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,% P1 ~$ I. q5 ?0 K4 O9 k2 t
  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.
  o7 U, m7 ~1 j  P" M* W  Loads are processed by each operator for the following time:
: j2 x3 I$ M  J% I  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
4 R* `3 F- r3 n+ k  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.9 c; B* m! D$ x0 b6 C
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.( O$ y! o% W6 ~$ ]- O# J, u. r3 ]$ E
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.  h$ r( i9 q% h, K, Z  N% N

. C% V1 C2 Z- G  Y% \% F问题:2 F  {8 A# T4 T5 T! _
After running the model for 10,000 days, what was the average number of loads in each process?

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