摘要

First of all, the paper collects the dental light-related technical patents, and then establishes technical/function matrix of dental light. Through word segmentation system, the paper defines the normalized numerical values of the important technical words in each technical fields of the dental light-related technical patents. The paper uses 3 main technical fields in the 1st-layer technical fields of dental light to form 3 technical improvement plans with technical interdependence. Through the steps of the modified fuzzy DANP, the related weight matrix is calculated. The modified fuzzy DEMATEL is applied to calculation. The paper substitutes the previously calculated interdependent prioritized weight W_C^D of the modified fuzzy DANP into equations S_i and R_i of the modified fuzzy VIKOR method, and calculates other related equations of the modified the modified fuzzy VIKOR method. Finally, the paper calculates the comprehensive index Q_i, and then decides and selects the most prioritized optional plan.

本研究首先收集牙科燈相關之技術專利，建立牙科燈之技術／功能矩陣，並透過斷詞斷字系統分別定義牙科燈相關專利之各技術領域的重要技術字常態化數值。本研究再將牙科燈的第一層技術領域的三項主要技術領域組成具有技術相依性的三個技術改善方案。透過修正式FUZZY DANP之步驟計算相關權值矩陣。其應用修正式FUZZY DEMATEL做計算。本研究將先前計算出修正式FUZZY DANP之相依優先權值W_C^D代入修正式FUZZY VIKOR法的S_i及R_i公式，並計算修正式FUZZY VIKOR的其他相關公式，最後再計算出綜合指標Q_i，決策評選出最優先選擇之方案。
