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,
1 p& Q. s' y- ~: J0 T: @  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.
; v6 ?  j8 G+ R3 T$ t5 L  Loads are processed by each operator for the following time:+ {$ l5 g9 B, @. L; t! s
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.. B2 C, \4 ^- f$ 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.. j  w. t9 d8 |" _( h
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
0 s' V$ \5 S9 [" A  SSend 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.) j; I7 y' b! R9 W9 v& r1 }
; w' r. L9 D6 b
问题:( P$ Q) P2 n$ J$ e7 d
After running the model for 10,000 days, what was the average number of loads in each process?; a' i* [( m( t+ r: n: @7 F
1 H, I% U: P* ^. o/ `' d5 B
不胜感激!
