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,
/ @6 ^7 x% I, Q7 ~! E( }# q8 J 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.& ^7 }5 c" x* l3 h: @0 x8 J
Loads are processed by each operator for the following time:$ g7 P# s! X, v2 t8 v9 Q
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins., ?! G+ T, R1 K$ p* U" D
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.4 W! O8 e7 d9 T u N/ c* m
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
4 v8 Q6 D) j4 x: e% w, rSend 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.! b3 ^: U9 E" H0 O0 x+ }; h
, `: g5 p" I) Z/ |. H
问题:% p' T- O) b3 J- M
After running the model for 10,000 days, what was the average number of loads in each process?5 n* M7 y( f1 n- Q7 R1 x
6 G" I n0 @$ z, m/ e* ?
不胜感激! |
