Abstract: Complexity of complex software system is not only due to the coupling correlation software itself, but also the Internet environment has great influence on the complex software system, and it has not existed independently from the external environment. Petri net uses of place and transition meet the modeling of distributed system, support concurrency and asynchronous, but the basic Petri net can't completely describe the characteristic of complex software systems with time constraints. A Petri net modeling method based on spatial and temporal was proposed. From aspects of synergetic and software behavior, constraints on the characteristics of spatial and temporal, this method established credibility analysis model of complex software system, and considered the influence of external environment for complex software systems, and analyzed credibility of complex software system under the environment influence. In complex network software system as the analysis object, the simulation results show that this model is able to analyze the credibility of the spatial-temporal complex software system.
