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,
! f3 J  M5 w" H$ z  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.
5 Y$ M% J" _1 h. y2 `  Loads are processed by each operator for the following time:1 e: m1 i: F- J+ z; X5 ~) D
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
, ^! n* X% l/ ~3 D' p! W2 }% y; k+ L+ C  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  ]. k# f9 f) D  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.7 l. n  r! ~$ u, u6 z5 e
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./ ]! y0 ^# K3 w$ a' {# s- U  U

, J4 D) K' B' K( y2 J9 b问题:
- S, q% G5 e0 |6 F! zAfter running the model for 10,000 days, what was the average number of loads in each process?; n- W) v. q8 n
/ Z- l8 Y: Z6 _1 U4 ~1 @
不胜感激!

Remember to turn off the animation before you run your model.
