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，
* V! _7 R, }: k% D 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.
) |7 h# i1 y$ {) |2 r Loads are processed by each operator for the following time:) C& W j- \ O5 n* u
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
0 e0 ], F: d8 c/ R$ w9 ~ 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.
. p, v; n0 ~( B! @% C+ b Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
8 [0 R+ P; D) X! c' I" R: _0 }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.+ q$ \) L+ F) J& t2 U9 `9 q( H
3 g7 [* j4 p6 N& Z
问题：
b1 R) D# P7 Y8 u% l. N* \, _After running the model for 10,000 days, what was the average number of loads in each process?: s4 X1 f: E6 N0 R" L7 t: D
) y6 l) d: |3 i
不胜感激！ |
