Analysis of Parts Weight of Railway Concrete Girder Bridges by Fuzzy Analytic Hierarchy Process

In order to accurately determine the weight of railway bridges parts, for railway concrete girder bridge case, this thesis is based on analysing the construction features of the railway concrete girder bridges and destructive characteristic of seismic damage and proposes a detailed method, which adopts combination of the analytic hierarchy process and the fuzzy synthetical evaluation. The weight of railway concrete girder bridges can be confirmed, by utilizing its logical and pairwise comparison method, Studies show that this is an effective method to confirm the weight of railway concrete girder bridges. It is of great value to quickly evaluate earthquake loss of railway bridges in the earthquake stricken areas.

The Risk Assessment Research on Real Estate Projects in View of Fuzzy-Synthetical Evaluation

It analyses different kinds of risk factors of real estate investment, and establishes a suit of scientific index system about the risk assessment of real estate investment. And this paper not only establishes the risk assessment model of real estate projects in view of fuzzy-synthetical evaluation, but also uses this model to make a risk assessment of Ganzhou Tianyue real estate project, showing the feasibility of the model by examples.
