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. G, H1 ] 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.
5 E; }. x5 c2 B) [" `" F8 M Loads are processed by each operator for the following time:
: O# ~/ O3 Z# g Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
5 N$ ?1 } Q4 u" Q- } 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." N& H& n" h; r& i$ E! q$ X9 G
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.9 l/ Z* q g% s! C& T% i1 \
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.
' M( q2 h% b, n' U' X, y3 ]" R& m p8 B9 [- D& v
问题:3 D9 v* U- p: ]2 Y* L3 D
After running the model for 10,000 days, what was the average number of loads in each process?! v6 P8 I+ }' m4 h+ C: E

不胜感激! |
