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,; F0 q+ O I6 j, i+ d
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.' j0 s* O' y7 d( h7 o% ], S
Loads are processed by each operator for the following time:
+ F3 |' {* S3 y' R8 l# z7 P' c Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.: r% {6 ~! H0 c, Y- q6 m
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 G7 \ l4 G' r Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
7 a8 T+ f! }$ J0 D# w" @; \" OSend 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.0 Q/ m6 O% g5 J. l' s* H

After running the model for 10,000 days, what was the average number of loads in each process?
