Value Engineering In Project Design Stage Optimal Scheme Is Studied

At present, the whole construction industry technical level is low, the technical basis relatively weak, and poor management, and building the enterprise the vigorous development exist considerably contrast. Meanwhile, adapt to the needs of the modernization of new scientific-technological progress has not yet fully establish and formation. Therefore, vigorously promote the construction of popularization and application value engineering to improve construction enterprise product value, promote the traditional product value innovation, cultivate and develop the enterprise’s core competitive ability and promote national economic and social sustainable development, has the vital influence and effect.Firstly, the paper according to the domestic and foreign research situation, analyses the architecture in different stages of the project application value engineering theory, the role that design phase application value engineering more efficiency and significance. Then, through to the architecture designing stage division and application value engineering content of research, from concept benefit buildings longevity analyzed the design phase factors affected the project cost, and raises the value engineering in project design phase scheme optimum choice of technical methods. In order to make the design scheme of value engineering design thinking has comprehensive and rationality, this paper put forward based on AHP and fuzzy mathematical value engineering function analysis method, the analytic hierarchy process and fuzzy mathematics theory together, develop the value function evaluation, gives the comprehensive evaluation of steps. Finally to an actual project engineering for example, from the project scheme optimum choice, scheme optimization, optimization of the structure are studied in detail from three aspects of value engineering application of the theory method.
