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,
0 s% S) ~7 f! L9 a 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 l5 B* o0 D/ b ^- c# ] Loads are processed by each operator for the following time:$ Z6 M% U8 ^; N& J8 x
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
1 V! e* I2 R t" E 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.7 T8 g" d! T% S: M6 D
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
5 k% q2 S3 ~7 m0 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.
. g7 H9 q! B$ B& Z7 N) W2 s
' Q( v, i: s4 P. K问题:; V' Z* U( C- |3 D/ q' N
After running the model for 10,000 days, what was the average number of loads in each process?
