Construction And Research Of Rice Information System Comprehensive Evaluation Model Under The Background Of Big Data

In response to the fast improvement achieved in modern agricultural information,it has been the call of the era that the informatization of rice production is constructed.Rice big data and rice industrialization are gradually realizing comprehensive and deep integration.A variety of rice information systems emerge as the times require.Problems in the use and promotion process also follow..Even though some systems have been developed,the amount of information is insufficient,the market situation is not accurate,and the role of information promotion is not realized.In addition,the analysis of the decision makers is not sufficiently provided.Facing with huge amount of information,users find it difficult to find their valuable information but have to get what is presented passively.In other words,both sides have devoted huge energy and money,however,no ideal effect has been achieved due to the information asymmetry.Therefore,the agricultural department urgently needs to evaluate and maintain the relevant rice information system comprehensively,systematically and scientifically,so as to avoid or reduce the loss caused by the blind customization and development of the system again.In order to solve the mentioned problems,this paper focuses on the construction and study of the comprehensive evaluation model of rice information system in the era of big data.Firstly,a large number of domestic and foreign scholars' literature on rice information system are consulted,and then the relevant influencing factors are analyzed and classified.3 first-class targets and corresponding 18 second-class targets were selected by using Analytic Hierarchy Process.Secondly the analysis hierarchy process is adopted to settle the indicator weights.Thirdly it constructs the fuzzy comprehensive evaluation model with the use of fuzzy comprehensive method.This paper also evaluates the performance of the selected system and verifies its feasibility and practicability,providing constructive suggestion for future improvement and promoting the fast development of agriculture in China.
