基于雙基點的灰靶理論飲料業服務決策最適模型

Grey target theory of Beverage Industry service decision-making based on two-point optimization model

針對傳統的灰靶決策模型利用加權的正靶心距對方案進行排序不考慮負靶心距對決策的影響，存在的不足之處。而且指標的權重一般是採用主觀定權法給出，未能充分利用已有的決策資訊等問題。提出了對傳統的灰靶決策模型改進的方法，利用加權的正負靶心距計算方案的貼近度，以貼近度為測度對決策方案進行排序，同時給出了基於雙基點優化指標定權重的方法，這種定權方法充分利用決策矩陣資訊，是一種客觀定權的有效方法。對飲料產業服務進行評價，模型中利用雙基點優化指標定權重的方法確定各評價指標的合理權重，應用灰色關聯分析法對定性資訊進行量化處理和比較，減少了主觀因素的影響，提高了評價結論的準確性，為飲料產業服務評價提供了一種新方法。

Considering the traditional grey target model which sorts the plans by weighted positive distance without the influence of negative approach degree distance to making decision. Index weights of which usually subjectively determined not fully using existed decision-making information has obviously defects. A method to improve the grey decision-making model is put forward which uses the positive and negative weighted approaching degree distances to calculate the close degree. This close degree is used as measurement to sort the plans and the index weight improvement method is given based on double base-point. This method uses fully decision-making matrix which is an objectively and effectively weight-decision method. In the model, this method is applied to determine the weights of evaluation indexes, the grey relational analysis 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 beverage industry service. Finally, the validity and feasibility of the proposed approach is verified with a case.
