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,
/ g* A- W. J C' e6 M( V3 Q 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.( i) P% e8 j6 V+ }! o
Loads are processed by each operator for the following time:% ]0 x2 w$ I9 z' `8 Z6 \5 r) [
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
; U/ r _3 }. E, D0 V 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.$ w! H8 Q) c4 h3 s0 f- B# r& P
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
_' W C" j2 A3 C+ {8 A) nSend 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.; Z0 `6 O7 Q7 [# H) z/ p
* x" j0 L0 a' m/ m" a; c问题:- i2 t. ~/ j, R& n
After running the model for 10,000 days, what was the average number of loads in each process?/ a. }& F" v. |; {! S9 f
