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,
: V6 [) O- k2 h) _* 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.
( X& k5 i/ M+ K4 N3 `* |9 Y  Loads are processed by each operator for the following time:
5 g' F$ U6 M+ i  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
9 ~$ Y) i$ ?8 j  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.8 K2 H3 v% _# M1 f% I- A4 y
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.7 x, A; ]# _" E! a. A; y& h
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.; g2 v  L7 A/ v- S6 ^! F

: y; v6 o& X8 Z, ?  dAfter running the model for 10,000 days, what was the average number of loads in each process?7 D5 c. ?- p/ w1 ]0 u
