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,; L: \' b8 A4 q0 p8 D
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 [& n/ \: B C3 W% v! {" S Loads are processed by each operator for the following time:
G" K7 J0 @( k" H" K+ z Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.; V- s' X- B @% d( 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.
! ]# y4 r; F% N, G$ c/ L: v Worker_C does the job in a uniformly distributed time between 30 and 90 mins.1 t3 c f' l. d( Z! ?* p3 O x
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.
