Abstract: Aiming at the problems in application of the evaluation method of weapon equipment development project, a risk evaluation model of weapon equipment development project based on support vector machine was proposed based on the explanation of the theory of support vector machine(SVM) and analysis of the feasibility of SVM in the risk evaluation of weapon equipment development project. The predicated results were verified by the project data, which shows a good agreement. Comparing SVM model with neural network and fuzzy comprehensive evaluation method shows that the SVM model has better ability of selflearning and feature extraction, and can provide a helpful suggestion for the risk evaluation of weapon equipment development project.
