Application Of Grain Reserves And Decision-making System Design Based On Android Platform

Grain reserves and decision information management system provides a reliable basis for the decision-making of the central budget.At present,a lot of information management systems of grain reserves and decision-making are the desktop system,which makes its application range limited.In the era of mobile Internet,it is necessary to keep up with the trend to develop mobile end of grain reserves and decision-making system.In April of 2016,China’s Android mobile phone operating system market share is 78.8%,increased by 4.8%compared with the same period in 2015.IOS’s mobile phone operating system market share has fallen by 4.4% and is 20.1% now.Other mobile operating system can be neglected.Because apple’s products are expensive,it is not suitable for food industries or firms to purchase in quantity,so the mobile APP development of the reserves and decision-making system based on Android platform is promising.Main achievements and innovation include the following several aspects:1.Three grain reserve models are studied,including the volatility index method for smoothing grain output,based on the sum,difference,proportion of grain reserve model and based on the food supply shortage of grain reserve model minimizing the loss.Through MATLAB simulation,the performance and applicability of three kinds of grain reserve prediction models are compared and analyzed.2.For satisfying basic requirements of the Grain reserves and decision-making system based on Android in network communication,data processing and interface design,the basic framework of system design is given.The input and output parameters of the above grain reserve models are analyzed in detail.Thereby the function design and overall design are realized,which is the basis of the following detailed design.3.Through the framework of the overall design,the basic technologies are selected,moreover,the pros and cons of the three development modes of the Android system are analyzed and compared.According to the system functional requirements,a hybrid APP development route is chose.The popular front frames of Bootstrap and j Query,ECharts library displaying charts and the third-party simulator tool of gennymotion are used,and from the development level of organization code of the system,the organizational structure of the system development is given in detail,grid layout of Bootstrap framework for interface development,the basic layout structure of three interfaces,including the function selection interfaces of the three grain reserves prediction model,parameter configuration interface and charts showing interface.the main interaction design of the above interfaces are presented.For the backend design,the data interaction between the client and the backend server and the format of the data and parsing function of the data are realized.Then the interaction based on JSON was shown by Echarts.After finished these all,the information of system was configured.Finally the scope of this system support versions are given.
