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,
. y v6 z! T) L" F! h) z4 m* o# q* W; m 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.! r4 L+ _4 i: s
Loads are processed by each operator for the following time:
8 A- y1 G! o2 q Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
m: H% u+ ?7 l4 i. h 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.0 x, }& Y0 n2 q/ @- }- c# W
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
" ?3 h2 k* c2 b3 }7 b$ l1 i) W: nSend 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.: T# X1 Z+ U3 B+ u1 p
- R$ m* g+ i7 C3 v2 h2 ]
问题:
$ e/ v5 u9 F2 `0 o; g* F- VAfter running the model for 10,000 days, what was the average number of loads in each process?
" n6 N- R3 w) K. y0 q" r( z% g& F8 z: k& n1 G$ V
不胜感激! |
