Aiming to some problems of armored vehicles research and development, such as few new types, few costing data and long research and development(R&D) cycle, it discussed some key techniques about R&D costing analysis of the armored vehicles, including identifying conversion coefficients about time worth, calculating dynamic and static expense and yearly expense distribution. Then, using parameters modeling method based on non-linear multi-regression technology, it built a prediction model between R&D costing and performance parameters of the armored vehicles. The model can be used to predict R&D costing of one new vehicle whose performance parameters are confirmed. The research results are significant to armored equipments life cycle costing (LCC) analysis that is comparatively weak currently in China.
