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,
4 j, \. G$ o' o, J9 R5 X' { 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., i9 u. L D c) n: u% p6 i6 J4 n
Loads are processed by each operator for the following time:
" m, g) C4 r. h0 D1 C% x Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
+ R9 p3 Q. E- R' _ 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.# D1 F3 a5 p ~" P5 J3 k
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
! A" J5 ]7 g+ a' c8 vSend 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.: C7 M# ~2 W8 ^# i+ c1 G
) A, o& ^' [, z3 M0 @7 { g/ ]
问题:& `) b' y/ o. x7 S
After running the model for 10,000 days, what was the average number of loads in each process?5 V+ j- z' I3 D: ~
3 K& p" _6 W S, c不胜感激! |
