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,9 ~5 e( a1 X# c) j
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.
- {8 v( O5 E* n* e Loads are processed by each operator for the following time:. j8 r( u$ T4 @" M' M0 d" ^
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
l, J7 |( \3 N; ]) m3 W 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.
5 P p2 r5 Q* A- L, p* w- N! U% h Worker_C does the job in a uniformly distributed time between 30 and 90 mins., w* n1 K: Z q9 y! R
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.( h3 s' ~5 E" Z+ D& i, ^

问题:* ]' k' o. n; G5 c* w
After running the model for 10,000 days, what was the average number of loads in each process?
