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,
5 V- M5 J: H& A8 I3 G; S8 D) h- J( s 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.
: n: C0 ~2 h0 f Loads are processed by each operator for the following time:
# i5 g9 D& W+ @! R1 I2 Z* \1 L Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
1 G4 s0 [! `2 q7 e9 k0 \ 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.6 Y3 P& n8 u& |8 D4 \
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.- W# s2 Y# O/ Y) O
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.4 ]- Y' y) n+ g R3 s
# U% j" H8 e# u# r h问题:. r' x' s# R9 \4 o' e( e# a D
After running the model for 10,000 days, what was the average number of loads in each process?
5 k9 [0 j, G& x6 X/ Y* A6 I: Y, q6 P1 y) d: V- W
不胜感激! |
