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,
# k2 [3 ~, {8 W 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.6 V6 q/ F; n+ }( r$ S D2 w4 k
Loads are processed by each operator for the following time:8 a8 h+ a) r8 S8 ~
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.1 t! l3 m- t& u" 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.% Y( ^7 b9 X/ m, q3 E( y
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.3 q" H2 T" n( v% |3 w
Send 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.$ W- s- @/ l* ^
