Research on the subjective weight of the risk assessment in the coal mine system based on GSPA-IAHP
The risk assessment index system is usually established in the coal mine system, and contributes of different indexes are reflected by their weights. AHP is one of the most common methods, but experts are difficult to make accurate judgment for the relative importance of indexes by 1 to 9, that the interval could be used to express relative importance of the assessment index instead of the precise is more easy and reasonable. In order to make full use of the interval information of the certainty and uncertainty, the calculation methods of interval certainty weights and interval uncertainty weights of the risk assessment index system are discussed by introducing GSPA, and a subjective weight based on GSPA-IAHP is proposed. Application shows that the interval information is discussed dialectically from the certainty and uncertainty embodies fully scientific and comprehensive.
