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,
4 D2 U+ h4 W9 ^ 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.
$ `3 l i/ R5 D; P3 i: I Loads are processed by each operator for the following time:
' [4 ]0 X% m- |+ V Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
0 c, K4 d$ D3 i- ~5 j' a1 q 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.
9 v8 R7 n% e; Q2 r! H, }1 ~ Worker_C does the job in a uniformly distributed time between 30 and 90 mins.8 \. l) j: Z% i
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.
( y2 ^# H) O+ S F
0 S+ [# O, S- J+ p, Y6 o9 Q; n问题:/ H5 V6 n" C% Q& ^$ {
After running the model for 10,000 days, what was the average number of loads in each process?( D) }: B; u0 B- ?% E. x/ ]; \
