Uncertain Inferences and Uncertain Conclusions
Uncertainty may be taken to characterize in ferences, their conclusions, their premises or all three. Under some treatments of uncer tainty, the inference itself is never character ized by uncertainty. We explore both the sig nificance of uncertainty in the premises and in the conclusion of an argument that in volves uncertainty. We argue that for un certainty to characterize the conclusi...
متن کاملUncertain Satisfiability and Uncertain Entailment
Uncertain logic is a branch of multi-valued logic for dealing with subjective information, which explains formulas as uncertain variables and defines their truth values as uncertain measures. In this paper, uncertain satisfiability is proposed to verify the consistency of a set of truth values for the formulas. Furthermore, for a set of satisfiable formulas with given truth values, the problem ...
متن کاملfuzzy simulation in uncertain circumstances
this article proposes composition of fuzzy sets theory with discrete-event simulation and puts it into application in order to model uncertain activity duration in simulating a real-world system. the purpose of this paper is to assess the usefulness of fuzzy simulation for modeling uncertain activity duration, especially when insufficient or no sample data is available. in this research, fuzzy ...
متن کاملThe origins of the developmental origins theory.
Current orthodoxy states that coronary heart disease results from the unhealthy lifestyles of westernized adults together with a contribution from genetic inheritance. This does not provide a secure basis for prevention of the disease. Geographical studies gave the first clue that the disease originates during intra-uterine development. Variations in mortality from the disease across England an...
متن کاملUncertain random logic and uncertain random entailment
Probabilistic logic and uncertain logic, as two branches of the multi-valued logic, have been proposed for dealing with knowledge with random factors and with human uncertainty, respectively. As a generalization, this paper proposes an uncertain random logic to deal with complex knowledge containing random factors and human uncertainty simultaneously, and derives a formula to calculate the trut...
