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,
: Q& o6 ?( u4 L1 {3 p  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' ^3 p* t' Z8 v  E: q! Q  Loads are processed by each operator for the following time:
, X6 ^' Z' l: X5 q1 e0 N+ @0 o  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
$ f% N4 K% R2 F3 L6 D; A$ X5 n  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.
4 ?, w# T7 ?  d- O: A2 Y5 c( h+ h9 x  Worker_C does the job in a uniformly distributed time between 30 and 90 mins., G% ]8 Q) V0 a  h) Z5 ~9 z
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.

问题:
6 [6 `' U, `4 B  k5 {8 |After running the model for 10,000 days, what was the average number of loads in each process?- ^+ Q# B( j5 {* n# N
