探讨和构建变精度近似算子与程度近似算子的新运算,提出了变精度下近似算子与程度上近似算子的差运算,给出了宏观算法和微观算法。进行算法分析与比较,并用一个医疗实例对宏观算法和微观算法进行了分析与说明。

The purpose of this paper is to construct new operation of variable precision approximation operator and grade approximation operator,and to explore its algorithm of calculation.We propose in the paper the difference operation of variable precision lower approximation operator and the grade upper approximation operator as well as the macroscopic algorithm and the microscopic algorithm,and make analysis and comparison on these algorithms.A medical example is utilised to analyse and explain the macroscopic algorithm and microscopic algorithm.
