Abstract: Based on uncertainty decision problems,D-type probabilistic decision formal context was proposed.On this probabilistic decision formal context,a new operator “△” was defined,the probabilistic concepts were obtained and the corresponding concept lattice was constructed.Then we defined the consistence of D-type probability decision formal context and studied the rule acquisition on the consistent D-type probability decision formal context.Furthermore,by eliminating the redundant rules,the rules were simplified.Finally,the algorithms for generating the probability concept lattice and acquiring the decision rules were presented.

Key words: Uncertainty decision,D-type probabilistic decision formal context,Rule acquisition,Redundant rule
