基于水利信息系统的运行与维护经费预算分析

Cost estimation of O&M for water information system

运用SAS软件对水利信息系统运行与维护预算经费进行了统计分析。结果表明:运行经费与维护经费以及运行维护经费与固定资产金额之间均存在极显著相关性;运行经费与维护经费拟合的直线方程为y=-2.0552+0.5529x,固定资产金额与运行维护经费拟合的直线方程为y=8.3252+0.0973x。

Statistics is carried out for the O＆M cost of water information system based on SAS software. The result shows that close relationship exists between the O＆M cost and value of fixed asset. The linier equation of operation cost and maintenance cost of y=-2.0552＋0.5529x, and linier equation of fixed assets and O＆M cost of y=8.3252＋ 0.0973x are given.
