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,4 S* _3 R% v' v9 g+ U3 F( I
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.5 r1 a: Z" y. V* |( E
Loads are processed by each operator for the following time:3 G* L4 y1 A+ b) k; a# O. Y( ~
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
* P$ T/ F" f* z( U/ L5 V o 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.4 s: t( Q& l g" t- P/ c/ K
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
8 W* U) [% g/ N# u- o' ~ tSend 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.

问题:
