| The project evaluation is an important segment of value engineering, and the science of an evaluation will influence the accuracy and choice of the project. The residential district program structure belongs to the certain limits of being used fields following the design concept, synthetic consideration and certainty for all sorts of elements, such as, program structure, building arrangement, road planning, landscape sight, the form of space design and the economics of techniques. According to these, people are able to obtain the total balance to the society, economy, environment and aesthetics. It may say that the aim of the program at the commercial residential area is involved in society, economy, environment and so on, which have contact with each other, at the same time they are mutual check, so which define the comprehensive speciality of the systems evaluation. Which is called the basic concept of commercial residential area.The text tries to exercise value engineering, adopt analytic hierarchy process (AHP). According to the programming design characteristics of business living area, on the basis of an evaluation index system, to build up many targets, multilayers comprehensive evaluations model. According to giving fixed amount expression to the opposite importance of each chemical element of each standard layer( standard layer), make use of mathematics method to express all numbers of important sequences with opposite chemical elements, then make sure the weighing of the evaluate index. After setting up comprehensive evaluation index sign system and being sure the weighing about an evaluation index, again making use of an expert to give marks, and passing a comprehensive operation, and then getting the final comprehensive evaluation results of the science and qualification, and so choosing the superior project from some projects. This evaluate systems adopt qualitative and fixed amount combining together, make evaluation's result more reasonable, science. |
