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,8 e" n5 t! K4 p# j" a# p
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.
2 _0 ? h; W0 d% d+ m Loads are processed by each operator for the following time:2 d& y* x4 n. p- `
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.5 M( x5 R3 E" {3 n( h" n6 @
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./ U5 z6 W. `' Q3 G7 l
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
; \" \% z( T/ H" _7 l! Y) r# vSend 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 Y; t: g5 U2 B8 A

After running the model for 10,000 days, what was the average number of loads in each process?
