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,
/ b. ~) n: J; s! z6 L( k 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.
* L; s: G! U6 J& y7 c Loads are processed by each operator for the following time:" ?5 A4 ]5 P2 d& l) [1 z1 {/ I
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.8 R T J* R4 W7 ^/ X; r2 {
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.& X& T2 e: q) l8 _. d; w2 i
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.9 Y% U& w4 Q/ h4 C9 U$ ]
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./ Y( }3 {% H& \! Q& |1 d, E* n

问题:. d" i) L( s1 o' c( a( b* ]
After running the model for 10,000 days, what was the average number of loads in each process?: U+ r; Z H4 [5 w( X
