基于逻辑公式的粒类互逆运算研究

Research on Granular Inter-Reverse Operation Based on Logic Formula

粒计算被公认为一种看待客观世界的方法论,是一种问题求解的计算思维方式和策略。基于此,以逻辑语义建立的粒类运算为基础,定义并说明抽象粒中的粒类运算是一对互逆运算,并利用信息系统中的等价关系和分明关系进行实例分析和说明,得出针对互补关系应用不同运算可以得到相同结果的结论。即对同一问题的解决,可以根据不同的条件,采用更合适的方式达到最优解决方法。

Granular computing is regarded as a methodology of understanding the objective world. It is a computational thinking mode of problem solving. On this basis, defines and explains the granular computing of abstract granule as inter-reverse operation according to Granular computing based on logical semantics. The conclusion can be obtained by applying different operations to the complementary relation. The research uses the equivalence relation and clear relation in the information system to analyze and illustrate the example, which shows that when faceing the same problem, there can be a best solution with a more appropriate way according to the certain condition.
