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,
( G/ N( P1 _5 Y3 m0 c 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.) ^ h- P* M. G* Y
Loads are processed by each operator for the following time:
; |, f }2 `3 ~: k Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
, Q. t) M/ s" P" d0 S$ g9 V" W! U 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.
& k" D/ C, b! g Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
# j+ f* E" q* f# O& Z, bSend 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.* J5 u2 L- H/ |7 k: i5 D" c, v% a
! ?+ F% \7 i* H, n问题:
! T; x. G5 }4 {& w3 i3 ?After running the model for 10,000 days, what was the average number of loads in each process?
