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,
. |+ Y) q4 Y; O2 G$ P3 D 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.; J/ x- i' b2 d, k; u3 q
Loads are processed by each operator for the following time:3 I4 I1 }, H( Q. e
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.' I7 B- Q$ Z( m" y$ d& G( E
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.: o8 p& M# @. _+ n
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
3 P+ {) ~0 V. Q- z; V- W4 hSend 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.. h. G% x$ @' H
1 T0 W, s3 u% ]! w9 |问题:4 g) m7 \+ P1 k- v! F9 `, v
After running the model for 10,000 days, what was the average number of loads in each process?

不胜感激! |
