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,/ q g O, O5 ]) X# A2 K
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/ e$ y; _: w) F
Loads are processed by each operator for the following time:
7 Y) }- O5 p+ j5 x# p; Q3 O# j) p Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.4 |3 G1 E8 Z! j/ O
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.
* z/ {7 N* h9 m6 q0 n Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
& W7 a3 T. A! WSend 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. C8 B, h$ s. ^+ l' r
5 q, {) m' \% y# k
问题:0 `$ r: B, i3 [" m
After running the model for 10,000 days, what was the average number of loads in each process?* V& ~* w4 C% [2 ^4 U
+ V4 L/ W9 c, R7 t不胜感激! |
