Original Dempster Combination Formula Calculation Function for DS Evidence Reasoning

The original Dempster combination formula calculation function for DS evidence reasoning is a data analysis method based on Dempster-Shafer theory. This theory extends traditional probability theory and is particularly useful for handling uncertainty and incomplete information problems. In practical applications, this formula can calculate weights from different evidence sources to derive more accurate conclusions. The calculation function can be implemented through the following steps:

1. Collect all available evidence sources

2. Transform evidence into DS evidence structures using basic probability assignments (BPAs)

3. Calculate belief degrees for each evidence set using belief and plausibility functions

4. Combine all evidence using Dempster's rule of combination, which orthogonalizes the mass functions

5. Derive conclusions based on the combined evidence through decision-making criteria

For detailed usage instructions, refer to the help documentation within this file. The implementation typically involves creating mass function arrays, handling conflicting evidence through normalization factors, and computing combined belief measures. Additionally, DS evidence reasoning includes various other calculation methods and techniques that can be utilized and extended according to specific practical requirements, such as alternative combination rules or uncertainty measures.
