Optimization Of Design Plan By Computer-Aided Selective System In Preliminary Phase

Optimal design is an important process in the preliminary design phase of construction project. In this phase it is important to verify whether the technology of the optimal design is advanced, whether the engineering structure of the optimal design is safety, whether the cost control of the construction object of the optimal design is the best. In this paper Value Engineering theory is used in analyzing. Because the analysis workload is heavy and it will cost much time and expenses in the preliminary design phase, it is necessary to look for a one shot solution to the problem. After studying of technical and construction feature, every possible design plan is analyzed from the technical and economic view by the application of value engineering theory. The artificial intelligence frame is set up by means of computer program. After running through the possible designs, the computer will pick out a design that would meet requirements of the owner as much as possible at the lowest cost. The computer-aided selective system has been applied in some construction projects and acquired good effect.
