LCC Value Analysis Based On The Theory Of Decision Research Project

Decision in research projects, cost analysis is a very important analysis. Cost analysis of the past are often only consider the project's upfront costs. With worldwide energy prices generally rose base, the increasing use of the product cost, makes the whole life cycle cost analysis wide attention. Life cycle cost analysis covers the entire project life cycle, guide people to consciously and comprehensively consider the project's construction costs and operating and maintenance costs. On this basis, with value engineering on the full life cycle cost optimization, get the best ratio of cost and function, in order to achieve a more scientific and rational investment decisions.In this paper, the construction project decision is a lot of reference to international and domestic literature, light of its own in the theoretical study and practical work experience out. Main contents of this paper are:1. Analysis of the decision of the research project background and significance of research, on this basis, the paper described the research methodology and the framework paper, and investment decision-making theory and the life cycle theory of domestic and international status of research on some analysis.2. Introduces the basic theory of decision making, including decision-making concepts, principles, procedures and methods; the whole life cycle of the basic theory was elaborated, including their content, classification, cost structure, analysis of processes.3. On a construction project phasing, cost element structure decomposition, Established a construction project life cycle cost estimation model, and analyzed to estimate the parameters of the model.4. Introduce the basic theory of value engineering, and AHP and entropy function method to determine index weight, value analysis model was established.5. LCC value analysis based on decision of the construction projects were examples of proof.
