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,; R8 K! v. v& `
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.4 o# G7 |: }1 `* e* o/ O
Loads are processed by each operator for the following time:
: Q9 E% E; x+ X% V1 G! { Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
c4 _1 H2 ^) \$ o( H 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.: M5 N3 |$ U' `3 L% c; z& t
Worker_C does the job in a uniformly distributed time between 30 and 90 mins., \' B: u) O5 F
Send 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.
6 d `+ O4 x8 L! {+ Z' |' W {: J# j! U
问题:& C* V# I, e) Z6 s+ O$ i
After running the model for 10,000 days, what was the average number of loads in each process?. t$ e. k, {7 \( A! C( ^

不胜感激! |
