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,4 N4 l1 e7 M4 J4 q
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.
# e1 y/ f+ z9 z" p2 U. a! |& g6 C Loads are processed by each operator for the following time:
# Q) A, J' Y& p O& N. m( M Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins. i( i2 D7 W6 m! n
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 a* {5 X! v: s
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
, @4 z4 z4 u% zSend 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.+ U3 d E* a% Y' o; ~ ~- I
