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,
- x. [6 o$ ?2 \: P0 W+ W  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.% A# \+ V5 g' C! O( r* F
  Loads are processed by each operator for the following time:
( j+ u7 T, M& Q4 V( k& S5 l& Y  i  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.5 K$ g" h8 n; l  \7 `9 K
  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.
5 B3 e, o: N* L- a$ S  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.4 P; G6 Z' s7 F
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.4 K2 f6 l5 Y# a$ s6 {$ ~

# }, p9 M$ q8 D2 C. B2 P问题:2 `8 Z5 V0 C: v9 L/ M2 C
After running the model for 10,000 days, what was the average number of loads in each process?5 e& V' b, f, v! N
, Y% i2 V4 c/ E1 g
不胜感激!
