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,
8 B5 A! P* P, G/ Q! ` 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 \( u6 K- S9 ~2 P+ q/ u
Loads are processed by each operator for the following time:
0 Q, h3 _& G2 A; S" K9 Z0 F Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.# V/ W$ y0 U' o; m* B; l! D7 t
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.
/ l) Q* B5 z; Y% \0 a Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
- {% [9 z: W. {. ^& BSend 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.
- T3 z. j: ?8 N* o6 p
( f$ U' t( E [, }问题:
5 f5 ?) C. Z+ M6 U- JAfter running the model for 10,000 days, what was the average number of loads in each process?* j% z# v3 i9 ]3 k) R* Z8 \
2 k- r, e; t+ p
不胜感激! |
