A dea-ahp-based method for evaluating the greenness of grain storage

Abstract

The invention provides a grain storage green degree evaluating method based on DEA-AHP, which belongs to the grain storage technical field. The method comprises the following steps of (1) determining an evaluating index system by means of an AHP (analytic hierarchy process) method, making the relations of each factor hierarchical and principled and distinguishing the affecting degree of each factor on an evaluation object; (2) determining the specific value of each index correspondingly in each grain storage scheme by using a DEA (data envelope approach); (2) and comprehensively evaluating the grain storage schemes in a way to consider the index weights. The green degree of each grain storage factor can be investigated. Therefore, the advantages and disadvantages of each grain storage factor are found. Further improvement can be facilitated. Meanwhile, multiple grain storage schemes are discussed and calculated together. Relatively strong comparability is achieved. High evaluating efficiency is further achieved.

Description

technical field [0001] The invention belongs to the technical field of grain storage, and in particular relates to a method for evaluating the greenness of grain storage based on DEA-AHP. Background technique [0002] With the strong support of national policies, my country's grain production has been high for eight consecutive years, but while the demand is also growing, the supply and demand situation is still tight. It is in this situation that the supply and demand situation is difficult to change, the importance of grain storage is highlighted. Under the connotation requirements of "food security" proposed by the Second World Food Summit in 1996, to ensure the level of food reserves, starting from the annual loss of food mildew and insect damage (the loss is about 8% of the food production), we must try our best Minimize wastage, ensure the nutrition and health of food in terms of quality, and do a good job in food storage. These are new requirements and new challenge...

Problems solved by technology

[0008] The purpose of the present invention is to overcome the deficiency of the green degree evaluation method of grain storage green degree, invented a kind of grain storage green degree evaluation method based on DEA-AHP, proposed 13 representative indexes, and combined DEA evaluation by AHP The single-factor greenness performance of 13 indicators has been improved, and the single-level analysis method has overcome the disadvantage of strong subjectivity, and multiple grain storage schemes can be discussed and calculated together. This method can not only reflect the preferences of decision makers, Moreover, the evaluation alternatives that can be objectively quantified are an objective, scientific, and quantifiable method for evaluating the greenness of grain storage.
