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,6 L3 H* E- p6 m( K
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.
4 Q3 }# A' a, y# a' z5 x; x5 B Loads are processed by each operator for the following time:
0 G6 p) `4 o/ N3 ]" j5 { Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.+ `' N2 v! H3 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.
$ S! K: w" i% _3 n# J8 X+ A |4 E7 z" A Worker_C does the job in a uniformly distributed time between 30 and 90 mins.; k c/ H, W9 p4 s, 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.3 ]* l* i8 m+ f$ s- ?5 L1 a
