摘    要:针对传统缓冲算子不能实现作用强度的微调,从而导致缓冲作用效果过强或过弱的问题,构造了变权弱化缓冲算子和变权强化缓冲算子.研究了缓冲算子调节度与可变权重之间的关系,并用遗传算法探讨该类缓冲算子的优化问题.研究结果表明,可变权重在功能上类似于高阶作用算子,但控制缓冲算子作用强度的灵活性则明显优于高阶缓冲算子.最后以我国能源消费总量的预测问题为例,验证了变权缓冲算子的有效性和优越性.

关 键 词:灰色系统  缓冲算子  作用强度  优化  预测

Abstract:Traditonal buffer operators can not realize fine tuning of effect intensity,which leads to problems that the effectiveness of buffer action may be too strong or too weak.Considering this situation,this paper respectively constructs weakening buffer operators with variable weights and strengthen ones,and defines the relationship between the regulation degree of buffer operator and their variable weights.Furthermore,we make further discussion on the optimization of this kind of buffer operators by means of ge...
Keywords:Grey system  Buffer operator  Effect strength  Optimization  Forecasting
