Research on Dataflow Modeling with Petri Net
一种基于Petri网原理的数据流模型研究

The dataflow modeling is indispensable in the process of information system designing and analyzing.Based on the data characteristic analyzing,a new method for dataflow modeling named DSPN was expounded particularly and the formalization and schema of the DSPN method were defined in detail.The speciality and ability of the DSPN were expanded with an example of getting the value of the fifth item of the Fibonacci numbers series.
