Uncertainty, Energy, and Multiple-Valued Logics

  title={Uncertainty, Energy, and Multiple-Valued Logics},
  author={John P. Hayes},
  journal={IEEE Transactions on Computers},
The multiple-valued logics obtained by introducing uncertainty and energy considerations into classical switching theory are studied in this paper. First, the nature of uncertain or unknown signals is examined, and two general uncertainty types called U-values and P-values are identified. It is shown that multiple-valued logics composed of U/P-values can be systematically derived from 2-valued Boolean algebra. These are useful for timing and hazard analysis, and provide a rigorous framework for… CONTINUE READING
