有效的行动过程是组织成功完成使命的关键.提出了使用动态影响网对行动过程问题进行建模的方法,通过引入因果强度参数,替代贝叶斯网络中的条件概率表,缓解模型在知识获取方面的瓶颈问题,给出了利用因果强度参数进行概率传播的具体计算方法;并用粒子群优化算法对模型进行优化求解.最后结合一个联合作战的想定,验证了方法可行性和有效性. The effective course of action is the key to the successful completion of the mission of the organization.This paper proposes a method to model the course of action problems by using dynamic influence net, introduces the causal strength parameter to replace the conditional probability table in Bayesian network, The bottleneck problem is given, and a concrete method of calculating the probability propagation using causal strength parameters is given. Finally, the particle swarm optimization algorithm is used to optimize the model. Finally, a joint operation is proposed to verify the feasibility and effectiveness of the method.
