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," i7 Y* R2 S7 U {% {
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.$ J& K' u& q; M& B" `
Loads are processed by each operator for the following time:
3 o6 T" h; `8 `! p+ q) c8 Z; J) e Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
3 Q3 j. u7 p- H, Y& O 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.
. t8 |! o) ^* Y1 P& w. n Worker_C does the job in a uniformly distributed time between 30 and 90 mins.5 ~1 x5 J. i/ 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.0 P% G$ c0 B5 h5 a* _* C
! y: w8 q0 @+ M1 n z0 t% q. P
问题:. U" @' Y; J8 ~, y6 T# o% s
After running the model for 10,000 days, what was the average number of loads in each process?
