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,
0 U3 ?# z# D" R# S6 K3 V$ @ 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.
; C0 W/ z) z- I Loads are processed by each operator for the following time:' o! x0 g$ v! D% X: R" ?8 q& C6 c
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.: J; T$ @1 l- j7 R) c, V" g
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.
. M5 ~0 [4 Z/ b% ^8 _# X' S Worker_C does the job in a uniformly distributed time between 30 and 90 mins.. ]* _! i. @" G: [9 l. s
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.! x# f. i, G" N% F: Q
3 B! n4 t( w; m5 Z; @
问题:, I: h% _% Z0 i4 {, x! F; g- v) Z
After running the model for 10,000 days, what was the average number of loads in each process?
