摘要
提出了一种基于粗糙模糊集的数学规划模型,该模型利用粗糙模糊集中的上、下近似之差表示模糊规划模型中的容差,可得出系统的客观容差,为解决基于粗糙模糊信息系统的规划问题提供理论参考。
The mathematical programming model was proposed based on rough fuzzy sets,the model utilized the difference between upper approximation and lower approximation of rough fuzzy set to express the tolerance of the fuzzy programming model,the objective tolerance of system can be obtained,with theoretical reference suggested to solve the problems on planning based on rough fuzzy information system.
