Mining weights of land evaluation factors based on cloud model and correlation analysis

Abstract

The veracity of land evaluation is tightly related to the reasonable weights of land evaluation factors. By mapping qualitative linguistic words into a fine-changeable cloud drops and translating the uncertain factor conditions into quantitative values with the uncertain illation based on cloud model, and then, integrating correlation analysis, a new way of figuring out the weight of land evaluation factors is proposed. It may solve the limitations of the conventional ways.
