Complexity evaluation and empirical analysis of organization management system of coal resource consolidation

Complexity elements of organization management system of coal resource consolidation are analyzed and a set of evaluation factors is established. The concept of information entropy in the information theory is used for measuring the complexity of elements. The value of information entropy is calculated,which is used for building eachlayer’s entropy vector, and the entropy vectors make up entropy matrix. Eachlayer’s entropy vector is analyzed synthetically through the improved principal component projection method. The projection values of entropy vector belonged to each layer is viewed as the comprehensive complexity value. Based on this, the layers and factors are established, having an primary influence on thesystem’s complexity. In the end, taking the coal resource consolidation in shanxi for example, the above method is proved to be operable and reasonable.WT
