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,
. h: e- I5 G+ y# Z! T; p- X 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.
. h" S; _/ k! S, a3 h) A$ Y+ u Loads are processed by each operator for the following time:& Q, |# i# F( Z } d( u; C
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
. S" M) | C: a8 {8 Z1 {' f 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 u( n9 U6 }' z Worker_C does the job in a uniformly distributed time between 30 and 90 mins./ ?& m. h6 [1 d6 O$ r; A9 C
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.
1 O( R [0 I& `7 h) d4 G" `( V- T! f; f$ g: W: T
问题:6 E+ m) q1 G: d+ Q& K" h3 e
After running the model for 10,000 days, what was the average number of loads in each process?( E+ {# {+ G' b- S: B0 s) K6 X
