【摘要】 对双代号网络图节点进行编号是网络图自动生成系统的重点与难点,本文提出了一种改进的网络图节点编号方法,对工序排序优化了工序集的邻接矩阵,解决了传统方法易出现回路的难题;运用系统工程思想,紧密结合编号原则,对工序进行集合运算,简化了操作,保证了编号的唯一性与正确性。更多还原

【Abstract】 It’s difficult to number the node of dummy arrow.for this problem,this article gives an im- proved solution,which optimizes the adjoining matrix of work procedure set with sorting work procedure so that settles the loop problem with traditional method.According to the principle of numbering node,the method a- dopts the system engineering theory to set up operation of work procedure,so the operation is predigested, which ensures that the node is unique and valid.更多还原
