The evaluation on land exploitation and consolidation project are fuzzy multiple attributes group decision-making under uncertain environments of some qualitative and quantitative indicators. Due to the plurality of the evaluation indicators and the limitations of traditional methods, the evaluations on land exploitation and consolidation project were not so effective. How to synthesize the decision-makers' qualitative judgments with the quantitative forecast data of the actual project is the key to solve the evaluation issues of land exploitation and consolidation project. Vague set theory is superior to fuzzy set theory in quantifying the decision-makers' judgments. This paper proposed a new approach for the pre-evaluation and decision-making of land exploitation and consolidation project based on vague set theory. The illustrative example indicates that the proposed approach is effective.

By the body-fixed coordinate, Coriolis' theorem and Cardan angles, a kinetic model of a high-temperature ladle carrier vehicle, which has 30 degree-of –freedoms, is built. The model could be used to predict the rollover of the vehicle. The inputs of the model are steer angle and rotational velocity of every tire, and the outputs are the motions of the vehicle’s body and the forces on the body and the tires. The model is easily to be applied on other vehicles, which have different numbers of shafts.

This paper firstly has systemically discussed on the concept and theory of urban fabric; Secondly This paper discussed the basic principles of applying GIS (Geographic-Information-System) and MAS (Multi-Agent-System) technologies in the research of urban fabric; Lastly Wuchang District of Wuhan City has been studied as an example in this paper, Based on GIS technology, urban fabric characteristics and indicators was computed and analysed to obtain the cognitive and interpretation of the status of an urban fabric.
