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 S. ?7 k$ T+ Y8 \, @1 w/ Z+ C* C$ T, c 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.
& k% }7 `! f. T8 J1 y2 L" p$ l Loads are processed by each operator for the following time:
/ `9 L9 _; h6 G+ K% z- X% {; o Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.% d/ d1 ]. N; n" ^) ]
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.
$ f" u$ u& t) a: s5 A Worker_C does the job in a uniformly distributed time between 30 and 90 mins.6 I/ D/ j4 ^8 C/ ~1 u! W
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.

问题:7 w* Q* J4 @/ Q& z' T T
After running the model for 10,000 days, what was the average number of loads in each process?
