Research On The Cost Management Optimization Of Special Research Engineering Project

China as a big developing country,the rapid economic is developing.To establish the power of the ongoing economic and social development,it needs the innovation of science and technology support.As the country to the rising importance of science and technology,it puts forward the overall objective of an innovative country,the scientific research project ha s entered the phase of rapid development.A good scientific research platform construction can improve self-directed innovation capability and ensure the smooth progress of the research project,so it has important significance.Project cost management work,on the basis of reducing waste and keeping good quality,can create more economic benefits.Along with the increase in scientific research and special engineering project,due to the project itself is a o ne-off,and plus special engineering characteristics of scientific research,it makes the project cost management of the scientific research and special engineering itself there is a big difficulty,many management experience is only a reference,in the process of practical operability is not good,so not only will building engineering project cost management of related methods and measures applied in scientific research and special engineering project.Aiming at special research project cost management present situation research,only in special project to explore design suitable for scientific research project cost management optimization model.By based on analysis summary research special engineering project cost management status and problems of cost management,this article selects the larger impact cost of design and construction of the two phases of the project,the proposed special scientific research projects of different life cycle stages with different optimization model of project cost management.Project design phase using the value engineering principle to construct the project cost management optimization model,including the function object selection,design cost coefficient of determination,value evaluation model of design,use of value coefficient calculation results and improve the method of consultation,etc.Project construction phase for project management target factor analysis,using multi-attribute utility theory to build the integrated optimization model,including models and assumptions,the premise of time limit for a project,co st,quality of multi-attribute utility analysis and the establishment of multi-objective dynamic optimization model,the rational selection evaluation function of the model,and use genetic algorithm to solve this phase the established model.This paper take the case of research activities building project,there have to gather information on data of research activities building,analysis and study of research activities building profiles,research activities building cost estimates,project scheduling work,so as to verify this optimization model,and prove its good scientific and practical,for other special engineering project cost management research provides reference.
