Hierarchical Evaluation

In view of the uncertainty transformer state information, state of transformer hierarchical evaluation model is established. Firstly, index system of transformer state is formed; Secondly, in order to get comprehensive index of state, grey clustering method is used for monomial index clustering analysis; Finally in the basis of improving synthesis rules of conflict evidence of D - S evidence theory , clustering coefficient is used as the basic probability assignment function to evaluate the overall state of transformer. Example analysis results show that the proposed evaluation model can accurately grasp the running state of transformer and provide guidance for transformer condition overhaul.

Hierarchy Process

Operations research as a branch of comprehensive and multidisciplinary cross science, there are two types of decision problems. The first one is how to make use of resource to fulfill the tasks as much as possible. The other one is how to Using the least amount of resources to complete a certain task. The planning model about resource utilization in the factory is built through the investigation and analysis. It uses limited resources to complete the production task at most. In the actual problems of the university financial management and daily life, multi-target optimization is necessary. Analytic hierarchy process is used to built Hierarchical evaluation model and make decision of how to select school for graduate education.

Hierarchical Evaluation

In order to exist and develop in an unpredictable and rapidly changing surroundings, it is necessary for enterprise to have an agile information systems to support its success. An agile information system is the one can reconstruct itself and adapt quickly to it’s environments. The article will begin with the focus on one more properties of information system agility, explain its definition, build its evaluating indicator system, provide the hierarchical evaluation model of information system agility, and describe the evaluation process and mathematical method. Finally, by using an example, the practicability and validity of the evaluation model is proved, comprehensive and scientific evaluation of information system agility is achieved.
