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,+ o% V4 s% a6 R, d8 r _# i1 W- }7 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. O) m# v K s! B- y U5 |
Loads are processed by each operator for the following time:/ H. [# G% C$ D K. U
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
1 o- Y7 ~# K& a/ q. d. F 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.
) O. O* Y, C2 @ i* @ Worker_C does the job in a uniformly distributed time between 30 and 90 mins." b1 z. l( B! \6 B$ G
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.1 X9 B$ e* G& t [" V. j9 F" p

After running the model for 10,000 days, what was the average number of loads in each process?/ E; D1 W3 t3 P0 E* B" ?% M. ]
