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, T* I! L T0 q! a3 r/ i 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.
7 Y- r: K9 ~1 o+ h Loads are processed by each operator for the following time:. g( m1 z6 s- @$ U, m6 O
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.1 o" r$ Q6 D- R5 k! P
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& H% ]8 d- a* B' t Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
6 k0 r9 a% e4 _- Y8 OSend 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.; {* _4 B+ ?1 x7 a% F* }
4 i5 E* \. |3 D
问题:4 u& O2 H, N+ S: F$ [5 |
After running the model for 10,000 days, what was the average number of loads in each process?
