The quantity of components of a function block in digital human-computer interface of nuclear power plant brings heavy burden to operators and influences human error event to occur. In this paper, a complete optimizing process for the quantity of parameters in function block was established, and a few key points in the complete optimizing process were discussed. Using dynamic fuzzy method, the fuzzy segment was formed by quantity of factor, the middle search fetching method that could well improve search performance for fuzzy quantity of segmen...
