Conflicts in land exploration are incisive social problems which have been the subject in many studies. Risk assessment of land conflicts is effective to resolve such problems. Specifically, fuzzy mathematics and the analytic hierarchy process were combined together to evaluate risk in land conflicts in our work, which is proved useful to solve uncertainty and imprecision problems. Based on the analysis of the principles for the risk assessment of a land conflicts index system, a set of risk assessment indexes using the fuzzy analytic hierarchy process (FAHP) was presented. The results show that the overall risk is at medium level, and the risk of the feasibility index and controllability index need to be paid more attention to. The contribution of this article is reflected in two aspects: (1) the application of FAHP in risk assessments of land conflicts is effective and valid; (2) it is helpful for governments to establish a stricter management system of work safety for conflicts in land exploration based on the risk assessment results.

The tradition elevator risk assessment model depends on the expert experience, which causes that the assessment process takes a long time. To deal with this problem, this paper proposes a new risk assessment model which is based on fuzzy analytic hierarchy process (F-AHP) and artificial neural network (ANN). This model is applied to the risk-assessment of elevators. The results show that the assessment time is shorter and the accuracy is not lower, in comparison with the traditional model.

This paper concentrates on the risk assessment problem for accounting information system, which is an important problem in enterprise informatization construction. Firstly, we show that process of the accounting information system is made up three parts: 1) Implementation process of the accounting information system, 2) Processing of the accounting information, and 3) Management process of the accounting information system. Secondly, evaluation index system of the accounting information system risk assessment is given, which is a hierarchy structure with three layers. Thirdly, we introduce analytic hierarchy process to solve the problem of accounting information system risk assessment estimating. In analytic hierarchy process, an overall object is positioned in the top level, and the criteria in the middle level represents to the overall object. Furthermore, the perfectly consistent case where the pairwise comparisons matrix can be defined using a priority vector. Utilizing the interval weights, the maximum interval can be obtained, and then the index weights estimating problem can be converted to a linear programming problem with constraint conditions. Finally, experiments are conducted to make performance evolution, compared with expert’s evaluation and very positive results are obtained.
