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,
; @+ z; U# x/ I  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.
& R+ N- [* b+ j. x  Loads are processed by each operator for the following time:
. n9 a/ B4 K1 ^% T9 V  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
3 b1 m+ }* _( a" u/ G) ]' |7 G1 K0 k- q$ @  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.
( {  q  m7 X# m3 u  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
8 E/ }% A" Y* ?& M2 HSend 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.8 h# q& N; v: z+ f
9 Z) ?* L% a$ t, J& a; {
问题:/ O5 Y) o0 O7 u! E
After running the model for 10,000 days, what was the average number of loads in each process?) }1 H% ^" O, }) g$ G' z

* o% e! ?; f2 h不胜感激!

in P_C, you need to send to die.
