摘　　要：建立了基于变精度粗糙集的战时导弹需求量预测模型。在对导弹需求量影响因素分析的基础上建立了导弹需求量预测决策表,采用基于属性重要度的启发式算法求解β近似约简,从而获取导弹需求量预测的相关规则。结果表明,该模型具有一定的有效性,为战时导弹需求量预测提供了一种新的途径。A missile requirement forecasting model in wartime was established based on variable precision rough set.The decision table was established by analysis of the factors that affected missile requirement.A β-reduct was solved by heuristic search algorithm based on attribute significance,and the rules of missile requirement was acquired.The results show that the model was effective,and was a new approach to forecast missile requirement in wartime.

关 键 词：导弹 需求量预测 变精度粗糙集 属性约简
