Decision-making analysis of equipment support system assessment based on cloud model theory

To solve the vagueness and randomness of knowledge representation in the process of decision-making analysis of equipment support system assessment, the paper applies cloud theory to build valuation model. According the analysis about the equipment support system, the input and output parameter of valuation is defined, and the concept subsets are also designed. Based on the research on the cloud theory, the paper designs the multi-condition and multi-rule generator, and introduces the detailed process of calculating. Finally, using the application example is to demonstrate the method.
