Fuzzy Grey GM(1,1) Model of Maintaining Cost for Torpedo

摘要

In the paper, Establish the grey model of maintain ing cost for torpedo, using the data for several years To solve this problem that historical data at different time have different effects on the model prediction, processed raw data using fu zzy meth od. At th e same time, wea ken the randomn ess of the data by processing of weakening buffer operator. Forecast results show th at this meth od has pracOcal valu e.
