Fuzzy grey model of base level maintenance time for torpedo weapon system

The maintenance cost of base level for torpedo weapon system is the highest in the three levels maintenance costs. The maintenance time of base level should be forecasted to use money in reason. Based on the thought of fuzzy theory, the AGM(l, l, ω) model is brought forward, which is developed form of grey GM(1, 1) model. At the same time, AHP method is used in confirming the best weight value of the AGM(l, l, ω) model. As an example, a model of base level maintenance time model for torpedo weapon system is set up. Result indicates that this method can achieve satisfactory precision, and has practical value.
