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,9 o5 a0 o/ e) E1 E9 ~ A: W/ R
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.
6 M1 h2 b$ H, g6 t/ q8 w Loads are processed by each operator for the following time:8 @9 V3 Q7 Y( T9 }1 g5 i
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.3 A: w0 W+ m* f/ Y: 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.& x' A) u+ K- V o# R
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.5 |" ?, L6 }( x, s, S- m0 o
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.5 s8 z, Y5 d/ J6 F$ }; }
5 @' I; u) m0 o, X
问题:
/ C* a" a, N. H. I9 M Z0 YAfter running the model for 10,000 days, what was the average number of loads in each process?

不胜感激! |
