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,
6 m$ d" j3 o g8 l/ F3 g( @; h 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.
9 }0 I5 d/ ?9 E0 a# T Loads are processed by each operator for the following time:
' ]' U" [ b/ Q. C7 u! T9 u) e b' D* b Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins./ n3 t% Z- E% Z; [
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.2 B5 i/ C* x, X9 X
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
5 i5 D/ s- `/ N% M# L5 FSend 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.
/ f+ {+ S7 T' t. m; p
: m0 k( I) ?% n8 L# o问题:! c4 Z- L5 q1 M4 b a. W
After running the model for 10,000 days, what was the average number of loads in each process?
3 s9 U% {8 U1 A8 K7 R- L$ _' k+ L% E5 }: d/ r6 G
不胜感激! |
