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,
, F6 [+ C' x7 A3 h7 Q( F/ p, u 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.
+ k' Y: A0 c B Loads are processed by each operator for the following time:1 u0 J, |5 @! G$ T" b* }
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
" E8 m, ]' v/ D" `) x; J% k 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.
7 i y* X6 W. l4 B Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
$ A# z3 Q3 H5 R YSend 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.$ R2 L7 H0 ^% F! @6 A
m5 d9 C4 Y* R2 _* \
问题:
( V, Q6 A+ y) A0 E" w% SAfter running the model for 10,000 days, what was the average number of loads in each process?
* E0 o# y3 L4 p) O( W4 Z% Z/ c8 X4 P" v9 J# A V* t
不胜感激! |
