| Abstract: | This paper first introduces briefly the Rough Set( RS ) theory,which is a new theory in intelligent data processing;discusses the method of decision analysis based on RS ;advances an optimization idea of continuous attributes discretization;and explores the problem of oil and water beds identification with RS theory as well as logging data. The result shows that the method has the characteristics of fast computation,easy realization and attributes optimazation available etc.,and that the identifing tally ratio of the method is better than both the manual and the BP network methods. Therefore,the method is applicable |
