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,% W+ h4 F7 ^4 _9 o( ~
  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.8 Y( W9 M5 P2 G; J) t
  Loads are processed by each operator for the following time:
2 J5 a  D4 K& V) ?9 M$ U; N  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.+ P: Y& G3 v5 ~) r0 \
  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." S6 r3 @9 z* l7 d3 e4 z# J
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
# i# Q4 \5 h! u; g. L9 bSend 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.
2 P* a% [) }0 F$ G! B# Y
4 B6 E. [# K7 _) C' B$ I问题:; O+ f; _4 y: P; R; e
After running the model for 10,000 days, what was the average number of loads in each process?
