Evaluation method research of human safety behavior based on rough set theory

The field test of comprehensive psychological measuration scale for safety behavior to 237 miners of different work types was carried out, so knowledge system about miner safety behavior indexes were constituted. By the rough set theory, the core attributes were worked out through the attribute reduction to the index knowledge system and the significance degree value of every condition attribute element was known by calculation. Finally, the index evaluation method of human safety behavior situation was designed. Actual measurement showed that this method can be used to make survey with accurate evaluation result easily.
