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,
% C( ?, M/ W& I( M 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.
* h* F) _' p* _ Loads are processed by each operator for the following time:
/ x, B5 R7 \3 F% C8 W! [ Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.; ?( K: T' P2 x1 {
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./ g& @/ C+ h& s7 A6 F
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
" ]) ^1 o& ^4 N# mSend 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.
5 A6 E) a# ^9 o4 d' [
& d/ y% z( R/ T3 @3 F8 F& J1 s问题:
% s* ?' t) J* o* ^After running the model for 10,000 days, what was the average number of loads in each process?9 M' p: B) C2 J5 F% Z
X' P3 b- k* C1 h8 X9 B6 S不胜感激! |
