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,8 i W9 y1 \: G K: u; ]
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.
, C3 F& `4 H( b3 z Loads are processed by each operator for the following time:
4 W$ @$ G3 t! ~7 E Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
! f. R1 @, J# w$ G( N7 b 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.
) [( l! J$ Z9 I. p3 w8 [1 A9 |5 L7 t Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
6 L0 E3 M! R+ i' z+ W% mSend 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.
