灰靶理論的咖啡簡餐選擇評估

Assessment of the selection CafeDiner based on Grey Target Theory

將灰靶理論引入咖啡簡餐店選擇模式中，通過靶心度分析對4家咖啡簡餐企業的服務進行排序，運用貢獻度分析對選擇咖啡簡餐影響因素進行貢獻度排序，找出關鍵影響因素，並通過實踐對其效果進行了檢驗，效果良好。灰靶理論是處理模式序列的灰關聯分析理論，其核心概念是靶心度，可以依據靶心度進行模式分級。分析了影響選擇咖啡簡餐店的主要因素，並基於灰靶理論建立了選擇咖啡簡餐店評估與排序的數學模型，提出了應用灰靶理論進行咖啡簡餐店評估與排序的方法，為消費者或業者進行科學決策提供了理論依據。

Grey theory is applied into recognizing the core rigidities in high-tech firms, which ranks the firms according to the rigidity degree via approaching degree analysis and ranks influencing factors via contribution degree analysis. Grey target theory is grey relational theory of dealing with the lists of mode and its core concept is approaching degree. According to it, we can classify the modes. At first, this paper analyses primary factors influencing the selection CafeDiner and establishes a mathematical model for selection assessment on CafeDiner based on grey target theory. It shows a new method of selection assessment which provides academic reference the selection CafeDiner making decision scientifically.
