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,
$ n0 I+ Q. @. u5 W% ~ 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.
6 O2 h( x; j; [8 | Loads are processed by each operator for the following time:
# D6 v4 Y, e: @/ V3 { Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.- F, d; s; L# V5 t( V5 y- I
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.
' \; A9 r0 q' P$ z2 I. ]! h. J Worker_C does the job in a uniformly distributed time between 30 and 90 mins.

After running the model for 10,000 days, what was the average number of loads in each process?7 K; F) o% j# }8 M U6 {( f
