Reseach On Marching-on In-time Scheme And The Fast Algorithm Of Time Domain Integral Equation

Cost control of construction project take Construction project as a researchsubject.in order to control the construction project cost within the planned value ofdecision-making plan,it makes decision plan and does the process monitoring.Decisionplanning stage is mainly about the project feasibility study stage and the designstage,according to the project alternatives,the two phase form engineering estimate andbudget respectively.And to be the investment of construction industy decision-makingbasis.Process control includes the whole process of construction project:the Projectfeasibility stage,the design stage, the bidding stage, the Engineering constructionstage,the Project completion settlement The accounts of the project and so on.its maintask is to use professional knowledge as the tool,not to break the limit estimateinvestment decision as target and then doing moniter.the Decision-making stage need tooptimized scheme to control the cost of construction,the process monitoring need Theamount of investment as standard,adjust the deviation of engineering cost,then,realizingthe goal of construction project cost control.The project construction cost control is a complex and repetitive tasks.In theprocess of construction need to modify project cost again and again because of thedesign changes or some other causes.So,traditional manual method not only cause highlabor intensity, low efficiency but also easy to make mistakes. Therefore, developing areliable and practical application for for controlling construction cost is very necessary.With full understanding and analysis on the status quo of construction costmanagement, this topic designs and develops a set of construction cost managementsystem for solving current problems in cost control, by taking the requirements ofspecific construction cost informatization into consideration, utilizing B/S developmentmode and three-layer framework, applying Mysql data base management system andApache Server, with PHP as the development tool.The system platform help project cooperated-builing parties to determinereasonably and effectively control project cost during the decision-making andimplementation process.processing data effectively and accurately, quering andextracting the information about material equipment engineering.And through thepowerful web technologies for data transmission, sharing,making the cost engineers freefrom tedious and error-prone work.its also provide professional support for the relevantunits to implement the project management.
