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 y2 _: J' Q- ?* m3 _4 K 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.* Y. c" i' [5 z! \
Loads are processed by each operator for the following time:
- P# m) \: w; {; F! v Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.! h4 Y8 X g* _! F0 t
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.+ c* P- r; P6 W- A
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
/ O. f' f5 S/ x7 }/ L# {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.: k- Z0 U; k( D2 ~$ K
# ~/ ? s e* S7 z" a' ?问题:6 \9 A2 g( u3 B# i+ @4 M K- a, `
After running the model for 10,000 days, what was the average number of loads in each process?# Y* V7 H9 g- i$ p, i7 d! M1 V" E
( v! F! b5 j) Q ?' e
不胜感激! |
