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,
5 G8 b8 K) V I3 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.
, n2 A& v: A3 O2 L' H% ]$ J8 Z2 Q8 l Loads are processed by each operator for the following time:
- b, P- {4 j& R9 k+ v Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.; x$ Z* [. l; h" b% L& S
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+ L' B' j! a1 X; a( y Worker_C does the job in a uniformly distributed time between 30 and 90 mins.. i/ j% J7 N- G4 n Y$ w
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.+ I4 R# q1 i: {- L2 a8 X
}8 S5 Q a3 E' E! K6 p3 C问题:, B P% R. t5 S: e: e0 F; b* N1 b
After running the model for 10,000 days, what was the average number of loads in each process?, Q6 j3 B% V6 {: X8 D4 D
$ _: L. @+ r/ s( y/ G
不胜感激! |
