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,* U8 W5 m* U4 @" T) _
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.
: V! ^6 H. Q8 L) u: n Loads are processed by each operator for the following time:
% L% |" P, q" ]* V3 N Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
0 W* K0 T) R7 y$ P 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.9 W5 m: T q0 z7 |9 ~/ L; E
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
6 S) b2 c7 B o% YSend 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.
