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, r) Q: T9 X, n9 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.& h' w C( q& w9 L5 ?% ?
Loads are processed by each operator for the following time:
2 {& t( |% B/ B5 N' O; B Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
& D1 e/ Y. i- Z2 L) t/ o* l3 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.
; K' ^2 {; ]5 I' O5 V! E, Y Worker_C does the job in a uniformly distributed time between 30 and 90 mins.( y5 b z( ], [' z. P: p; p: l% C" A- ?+ V" P
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.
