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,, E9 @: z8 Q3 j2 Y/ [; T* {- 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.7 H& \2 @) ?5 e2 P, ]
Loads are processed by each operator for the following time:3 P* Z# F2 x8 Z; C' o
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
9 O. F7 f" j% p) a5 }0 X 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.
8 n* u! N6 ]& l* c, l5 z Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
# H2 P) e+ \/ m% FSend 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.1 k! ?* L0 A0 y" \) c
