摘要
文章是关于2020年“高教社杯”全国大学生数学建模竞赛D题前三问的研究,该问题是基于校园智能水表获得的实时数据,通过建立数学模型发现并解决供水系统存在的问题,这不仅能提高校园服务和管理水平,也能大大地节约水资源。对数据进行预处理后,利用EXCEL函数和SPSS统计分析水表数据的变化规律,基于多元线性回归,利用MATLAB建立水表数据之间的关系模型并进行分析。
This paper is about the research of the first three questions of question D in 2020"Higher Education Society Cup"national college studentsmathematical modeling contest.This problem is based on the real-time data obtained by campus intelligent water meter.Through the establishment of mathematical model,the existing problems of water supply system can be found and solved.This can not onlyimprove the level of campus service and management,but also greatly save water resources.After preprocessing the data,Excel function and SPSS were used to analyze the change rule of water meter data.Based on multiple linear regression,the relationship model between water meter data was established and analyzed by MATLAB.
