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 j! G e4 N, C( X6 I 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.) F5 T! F: \6 u. J
Loads are processed by each operator for the following time:
2 `% {6 [5 g9 [/ z# G8 `, @ Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
7 U* i- v" r9 N; j+ U4 H8 L 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.% n* Z& j; D- J
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
/ c, Z1 Z8 u4 n8 A, g6 g4 a7 V" hSend 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 O. w. v: F8 F3 s% X
" a" W) n g) I' ~; y: o f' }问题:1 t; f3 K m# y6 C% s, R+ `2 q. E! L
After running the model for 10,000 days, what was the average number of loads in each process?
