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,
n8 }9 t% a3 Z) w3 n 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., C" W0 H: {- C4 y$ q! W
Loads are processed by each operator for the following time:
& K) K) P5 U0 F, |6 o8 E Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
! B) U' t6 g! @2 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.
' q( ]! g0 @8 D: ~' {& |- q Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
% V+ f5 o. W0 a& D/ H9 ~3 vSend 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* I+ k8 s' J
2 p3 J- P- l @, @' |# y; T# G
问题:
* z2 X6 G6 y0 p2 G: pAfter running the model for 10,000 days, what was the average number of loads in each process?
