Abstract: This paper discusses several methods for assessing the effectiveness．In weapon system analysis, the first place is to select the character parameters of weapon system. The character parameters of weapon system are selected based on reduction of knowledge. A parameter effectiveness model is established by using support vector machine. The method is illustrated through examples. The results obtained from support vector machine method are compared with that from index method and neural network method. The comparing results show that the support vector machine method is more accurate and simple than the index method and neural network method.
