Calculating Method of the Number of Network Paths of Double-Symbo1 and Single-object Network Chart

This paper studies the factors which influence the number of network paths of double-symbol and single-object network chart and puts forward the ideas that nodes and arrows are the fundamental factors in forming the network paths,and the number of network path branches forming the arrow joining nodes along the advancing direction of the network chart are the decisive factors which influence the number of network paths.For the first time it advances a new concept-of the network path value of the network arrow and the calculating formula of the network path value and therefore has found a solution to the method of network paths value and diagram reckoning method calculating the number of the network paths.It opens a new way that higher vocational students are trained in practice of job and simple using.
