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,
. j/ ~* ?9 N9 Q. k7 c 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.9 G( |! z0 Y5 X6 t* Z J; c
Loads are processed by each operator for the following time:
2 z* Q6 d. O E7 U) Q1 d Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.( p4 P, _1 A+ q# e# 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.: n1 M3 k% T8 b4 }
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
- p. h$ [9 [0 J& p: L9 ESend 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.) ~( j% t& D6 N) h- F& a2 j
5 Q9 d( A% w% V/ o" q9 Z+ Y* V
问题:
- v, r+ u+ E2 }1 l9 r0 s/ VAfter running the model for 10,000 days, what was the average number of loads in each process?* t( N2 R0 ^* N- s
