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,! F: r5 t. J4 H' v
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.
1 C" k9 C6 ]- I Loads are processed by each operator for the following time:& p8 P: u6 L3 E# E, R. X1 i
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
* b8 G% c x% r9 k2 Z: A" y 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.
' f* s0 _# r. e# R Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
/ ~0 @, F/ a4 X: k* FSend 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.
