Z-Number Evaluation Using Categorical Probability Sets

The patent segments the probability distribution space into discrete categorical sets (e.g., low, medium, high uncertainty categories). Each category is associated with a representative probability distribution, transforming the continuous evaluation space into discrete manageable segments. This allows the system to evaluate Z-numbers by matching categories rather than performing comprehensive calculations across all possible distributions.

The patent creates a library of predetermined probability distributions that serve as templates or copies. When evaluating a Z-number, the system selects from these pre-computed distribution copies rather than generating new ones through complex calculations. This copying approach maintains measurement precision while significantly reducing computational complexity during actual evaluation.

The patent performs preliminary actions by pre-computing and storing probability distributions for various uncertainty categories before actual evaluation is needed. This preliminary preparation allows the system to quickly match and retrieve appropriate distributions during Z-number evaluation, avoiding time-consuming real-time calculations while maintaining accurate uncertainty assessment.

By using pre-computed probability distribution copies stored in a library, the system eliminates the need for time-consuming real-time calculations. The evaluation process becomes a matter of matching the Z-number characteristics against pre-existing distribution templates, dramatically reducing processing time while preserving measurement precision through the use of accurate predetermined distributions.

The patent changes the parameters of probability distributions by selecting representative distributions from predetermined categories rather than using arbitrary distributions. Each category (e.g., low, medium, high uncertainty) has associated parameter ranges or characteristic distributions that are optimized for that category. This parameter selection approach maintains measurement precision by ensuring that the representative distributions accurately reflect the uncertainty characteristics of each category.

The patent segments the continuous probability distribution space into discrete categories, each with its own representative distribution. This segmentation allows the system to maintain precision within each segment while reducing overall complexity. The segmentation is designed so that the representative distributions for each category accurately capture the essential characteristics of that uncertainty level, preserving measurement precision despite the simplification.
