摘要

鞋楦設計必需根據人體計測，其藉由人體足部的特徵加以設計，方能製造出最符合個人足部之鞋子。本研究主要以逆向工程掃描技術，取得鞋楦以及個人足部之外型資料，並建立完成重要之特徵曲線（掌圍、腰圍與背圍）之STL三角網格切層，以完成人體足部、鞋楦特徵曲線之量測計算，並進行模糊比對，找出各特徵區度之歸屬度，再由層級分析法計算各圍度之權重值，以建立人體足部與鞋楦關聯之舒適值函數。本研究以5組個人腳型與10組鞋楦作爲案例，進行舒適性分析比對，以找出最適合個人足部腳型之鞋楦。

Shoe last, which is the mold for shoe making, is the key issue for good shoe design. Shoe lasts are designed and manufactured based on the features, characteristics, and functions of human feet within anthropometry. However, people's feet are different, and, under the mass production specifications in the foot-ware industry the same type of shoe last cannot be used to make shoes to fit everyone. The main purpose of this research is to build a process to find the most suitable shoe last for making shoes for human feet. A fitness function is defined to determine the optimum shoe last
Based on reverse engineering (RE) technology, this research scanned the surface of human foot and shoe last in STL (Stereo Lithography) format. We proposed the STL feature-based slicing algorithm to automatical1y construct the three most important girth characteristic feature curves for human feet and shoe last. Fuzzy theory was used to analyze and build the membership functions of these three important characteristic feature curves between the shoe last and human feet. The analytical hierarchy process (AHP) was applied to compare the important index and decide the weighting functions for each girth characteristic to determine the fitness function in al1 shoe last databases for the feet Five case studies were implemented to find the ranking in the database of 10 shoe lasts. Final1y, this research, which defined the relationships between shoe last and human feet, could be used as a reference for design or making modifications in the shoe-making process
