摘　　要：讨论了BP神经网络进行R＆D项目中止决策时存在的缺陷,提出了R＆D项目中止决策的区域映射模型,结合教师区域的范围以及像点集合的平面分布特征设计了每个类的判定标准和分类算法。区域映射模型能够克服BP神经网络收敛速度慢、易陷入局部极小点等不足,保证了实际分类准则与训练准则的一致性,具有很高的识别率和比BP神经网络更快的收敛速度,是R＆D项目中止决策的一个有效的模式识别工具。In the paper,the shortcomings of BP neural network used for R&D project termination decision are discussed and region mapping model for R&D project termination decision is proposed. According to the boundary and distributing in plane,judging criterion and classifying algorithm are designed. Region mapping model can overcome the disadvantages of BP neural network, which has the slow convergence speed and may easily fall into local minimum points. In addition, region mapping model guarantees inherently the consistence of classification rule with the training rule. It has high identification ratio and faster convergence speed than BP neural network. It becomes an effective tool of pattern identification for R&D project termination decision.
