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,
8 a5 g, x& [" b* @ 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 {& k) F% W: v1 ]& R
Loads are processed by each operator for the following time:
+ U& d) U, {3 e% y) b {, d% O Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.& j, b! M8 ~) U8 X7 v% }
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 h! Y. Z! R+ n* {' T( @% m4 t- t
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
) \+ c. u8 f& D9 G8 Q. ?* xSend 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.
: s( o! D, s* w2 k; v1 S# C+ z3 j+ m- u2 S( f
问题:
! W: y$ Q8 B" eAfter running the model for 10,000 days, what was the average number of loads in each process?

不胜感激! |
