基于模糊模式識別法在速食店選址中的應用

Application of Fuzzy Pattern Recognition in the location select of Fast-food Restaurant

在建立了評價指標體系的基礎上，引入模糊優選理論的綜合評價模型，兼顧產品服務品質的模糊性、複雜性和難以量化等特點，對速食餐廳選擇模式進行評價。首先對定性因素兩兩定量化評價，並根據其貢獻大小確定各因素權重，最後用模糊優選與模糊模式識別兩種方法對方案進行優選，此種方法綜合權衡了多因素對結果的影響效果，避免了單因素決策的片面性和主觀認識的局限性，能較客觀的反映實際和人們對事物的評價。模型中利用二元對比法確定各評價指標的合理權重，依據所得結果對決策指標的重要程度進行排序，減少了主觀因素的影響，提高了評價結論的準確性，為速食店選擇評價模式提供了一種新方法。

After establishing the index evaluation system, the synthetic evaluation model with fuzzy optimization theory is introduced to evaluate the Fast-food Restaurant selection model, and to make the fuzziness, complexity and difficulty. Firstly, the qualitative factors are evaluated quantitatively two by two, then, weights of each factors are determined in line with its contribution, finally, the mine development scheme is optimized by two methods: the fuzzy optimization and the fuzzy pattern recognition. This above method balances multiple factors and its effects on the outcome, avoids the risk of subjective judgments and wrong decisions out of single factor. Therefore, it could reflects reality and peoples views without any bias more objectivity. In the model, binary contrast method is applied to determine the weights of evaluation indexes, to make qualitative process and comparison to the qualitative information, which reduces the influence of subjective factor and improve the accuracy of the evaluation conclusion, and offers a new kind of approach for evaluation to Fast-food Restaurant selection model. Finally, the validity and feasibility of the proposed approach is verified with a case.
