Abstract

The decision algorithm is the preferred filtering algorithm in data mining technology, andits results are usually chosen in the form of "if-then" rules. Algorithm C4.5 is one of the decisionalgorithms that takes advantage of the ease of understanding and increasing importance, and alsotakes advantage of the advanced information rate gain of its advanced ID3 algorithm. After thetheoretical analysis of the information, the algorithm C4.5 is selected to analyze the results ofperformance appraisal, and enterprise performance appraisal decisions by collecting data, preprocessingdata, calculating information gain and determining selection parameters. The system isdeveloped in B/S architecture, an R&D project management platform that can perform evaluationanalysis with decision analysis results evaluation tools and web coverage. The system includesinformation storage, task management, reporting, receipt and presentation control, informationvisualization and other functions of the management information system functions. They can realizeproject management functions, such as creating and managing a project, flow tasks, filling andmanaging information about functions, creating a performance evaluation system, creating reportsof various sizes, building management. decision decision algorithm as the core technology,the system acquires scientific significant project management information with high data accuracy,and realizes visualization, which can help the enterprise to have a good management system inlarge areas. Task management, reporting, audit control, information visualization and other functionsof the system's management reporting management functions are included.
