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,
& N0 G7 W8 H, S5 s* }2 a" `5 D 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.
. Z0 n9 L" i* \2 V' y7 S; l Loads are processed by each operator for the following time:- i" b2 C$ a( k* D W# H5 P# o @" I
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.: p* D8 Q# Q2 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.5 m- c( Q2 i2 ]
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.: K- I9 e8 G8 b# k" Q* H% 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.
/ m- f* I, S6 y9 ~& |
. d' g' s* A/ Z0 `9 L) Y问题:
& ?" [, T( f' d2 v6 |* `) J9 MAfter running the model for 10,000 days, what was the average number of loads in each process?
$ M+ |" o; f6 a, F# N, c1 O1 D) y0 J; |& c* }7 m
不胜感激! |
