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,
! I; v3 E9 m- i7 [, O( i 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.
5 J" f7 R: R) `4 y1 j- Z) \ Loads are processed by each operator for the following time:
2 v9 t( B+ i5 A3 O1 S6 F# d, l Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.3 t+ i9 J8 j' C; s3 k) ~
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 @: d% ~: U
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
) R1 G3 n+ s- ~& ]9 E4 dSend 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.
+ x2 @: \9 u; }* I- n2 U7 m" [* H7 _, P, d q
问题:& M' `4 s: U N/ L
After running the model for 10,000 days, what was the average number of loads in each process?9 J# n3 z2 R' k$ G# D
