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 V& ~: s5 J+ b) A. ?& O3 R  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.
  Loads are processed by each operator for the following time:
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
( N5 J& F& j8 Y( x6 G5 e: 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.
" `2 g" K* S: ^1 Q  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
. }4 f& R6 X) m9 s& F4 FSend 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.
" ?/ Q( A' A$ n, r7 a
问题：
6 ?, _& [+ }% y6 ~6 [After running the model for 10,000 days, what was the average number of loads in each process?

begin P_A arriving
move into Q_wait /*Capacity is infinte*/
