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," J5 x" Z8 Z- k0 O4 o) 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.& m. e6 o# q2 }- z$ s
Loads are processed by each operator for the following time:
* ~" g, f8 W. v, D4 ^$ u Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
; X+ r% \' H+ o1 c2 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.
0 Z$ B3 v2 Q: `& U8 N1 i8 ~8 g Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
h5 e8 ?# o9 G# h0 r8 _( nSend 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.# w: n# H0 a6 W7 ]# x' [
3 _1 k& T3 t1 t- h+ D问题:2 O1 n( S) D- }
After running the model for 10,000 days, what was the average number of loads in each process?4 e+ I5 T3 @, q5 a& _- d# x
