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,- T6 ~% M: ?+ m
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.' g8 k& w0 c6 G4 r$ L- A0 q
Loads are processed by each operator for the following time:
: P5 n# Q6 g+ v [! E9 K0 l Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
5 ]9 q4 N+ u2 X5 a2 U 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.
* ]" @$ v& N b9 z Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
, {% ?2 `! x% M# _- s& SSend 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.
