The Application Of Unascertained Measure Model About Selection Of Mine Truck

In this paper, the uncertainty of objective is divided into four kinds in this paper. There are randomne fuzziness,greyness and unascertainty. The difference and relation among the four objective are analyzed Among them the former three kinds of uncertainty have be researched widely and unascertained mathematics are introduced in mining system to settle the forth kind uncertainty.The comprehensive evaluation model of Unascertained mathematics is set up to settle the selection of mine truck which belongs to the comprehensive evalution of unascertained objective. In the paper, the index of seclection of mine truck is studied and built up based on mine conditions and using environment of trucks of Wolongquan mine. The measure model which is improved based on the APH is used to compute the weigh of the index. What's more, the evalution model of unascertained measure is used in the selection of mine truck based on the item of Wulongquan Mine, and one better mine truck(TEREX(3303B)) is selected from three projects.In the meaure model, the objectivity is taken full advantage,when essentiality of the index is compared by esperts,and unascertained subjectivity of experts is taken into account,which makes the value of weigh more scientific and more reasonable,and satisfy the conherence.The evalution model of unascertained mathematics provide theoretics references for selection of mine truck.
