Abstract. High rocky slope is an open complex giant system with contradiction among different influencing factors and coexistence of qualitative and quantitative information. This study presents a comprehensive intelligent evaluation method of high rocky slope safety by an integrated analytic hierarchy process, extension matter element model and entropy-weight to assess the safety behavior of the high rocky slope. The proposed intelligent evaluation integrates subjective judgments derived from the analytic hierarchy process with the extension matter model and entropy-weight into a multiple indexes dynamic safety evaluation approach. A combining subjective and objective comprehensive evaluation process, a more objective manner through avoiding subjective effects on the weights and a qualitative safety assessment and quantitative safety amount are presented in the proposed method. The detailed computational procedures were also provided to illustrate the integration process of the above methods. Safety analysis of one high rocky slope is conducted to illustrate that this approach can adequately handle the inherent imprecision and contradiction of the human decision-making process and provide the flexibility and robustness needed for the decision maker to better monitor the safety behavior of high rocky slope. This study was the first application of proposed integrated evaluation method to safety assessment of high rocky slope, which also indicated that it can also be applied to other similar problems.

The calculation of weigh value and consistency of the judgment matrix of analytic hierarchy process (AHP) were studied in this paper. And the study was applied for coal mine safety assessment. Due to the particularity and complexity of the coal mine environment, to make sure the comprehensive assessment for coal mine system safety, analytic hierarchy process was usually used. It is an important problem to solve the weight value and consistency of the judgment matrix when applying analytic hierarchy process. To obtain the weight value and ensure the consistence of the judgment matrix is the main research direction of AHP. The genetic algorithm was applied to calculate the weight value and the consistency of the judgment matrix. And fuzzy comprehensive evaluation method was applied to evaluate the safety condition of the coal mine system with the method of weight value solution in this paper. Case study shows that the calcuation resuts of applying genetic algorithm to calculate idnex weight value is better than additional methods.

A new expert system was built for safety assessment of soft soil roadbed, in which the characteristics was taken into account by using Analytic Hierarchy Process (AHP) for identifying weight matrix of evaluating index, Fuzzy Synthetically Judgment for modeling safety evaluation of soft soil roadbed. The authors had attempted to develop the expert system to be comprehensive, concise, scientific, independent and flexible. Also, the system had been used to assess the safety of the Binhai highway of Tangshan, China. The results showed that the system is objective, feasible and practical, and can be used to assess the safety of soft soil roadbed.
