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" @3 T0 b. C( r) F1 ~: P 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.
( s$ F8 y6 h( W2 P, ]4 ]$ n Loads are processed by each operator for the following time:
) o- B3 E8 z! q5 K, @) r: } Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.- `/ |- q4 o2 T+ E% 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.
5 _5 U& S% S, ^# F7 |7 l, P Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
R' j) Q, ]4 B% Q1 }& cSend 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.

问题:
