本論文根據關聯結構(copula)近期的發展，探討關聯結構相關模式及結構，並運用有規律性的萄葡藤圖表，組織這些關聯結構。為了幫助高中職了解學生在校成績與聯考成績之間的關係，我們利用某高職資處科學生在校成績及四技二專聯考成績的資料建構關聯結構模型，並進行適合度的檢定。最後我們嘗試應用在最佳化製程的運用。

The preset study aims to examine the copula models and constructions based on the recent development of copula .We apply a graphical model denoted the regular vine to organize copula constructions.To enable the authorities concerned to better understand the relations between students’ academic performance at school and the score in the technological and vocational test.We utilize data from students of department of data processing at a vocational high school to construct copula models and perform goodness of fit test . Finally,we try to apply it to the optimization of the manufacturing process.
