A fuzzy logic information processing system and method are disclosed that may be used not only with known or definite data input but also with uncertain data input. The uncertain data input may be represented by a set of values wherein the possibility of any particular or specific value within the set being the true or accurate value is uncertain. The preferred embodiment of the system provides for an extensor to extend or map a representation of the uncertain data into at least one additional dimension related to dimensions of a set of rules used for making fuzzy logic inferences. The set of rules may be provided effectively in a mapped or graphed form. The set of rules and uncertain data are combined, for instance by locating intersection regions, to produce an output set that may be also be described as a map or plot. In a presently preferred embodiment the uncertain inputs and rules are represented mathematically or symbolically and then operated on to produce an output set. A projector then projects the output set to the desired output dimension as an output for the system. The system output may then be used for control purposes such as, for example only, a combat control system to provide a tactical picture, decision aid, presets for a guidance system, or the like.

[ What is claimed is:] [1.]1. A fuzzy logic system for processing information from at least one input that is associated with one or more physical phenomena, said at least one input being described as an input set including a plurality of possible values with uncertainty as to which of said plurality of possible values is the actual value of said at least one input, said fuzzy logic system comprising:an extensor for operating on said input set to produce an operated set of values;an inference engine that includes a plurality of rules related to said one or more physical phenomena, said inference engine being operable for comparing said operated set of values with said plurality of rules for producing a conditioned set of values; anda projector for producing an output signal from said conditioned set of values.
