Responsive space launch is currently developing rapidly and has application cases in many fields, with advantages such as fast response speed flexible networking. Aiming at the efficiency evaluation of responsive system, this article first summarizes typical process launch, then gives a hierarchical model system based on timed colored Petri nets, including top-level model, demand command decisi...

Despite the abundance of workflow analysis techniques from control-flow perspective, there is hardly any method for workflow verification from data processing perspective. In this paper, we restrict the WFCP-net, a Colored Petri Net with WF-net structure, to formally describe the key business entities in a data-centric workflow model. Then, we use ASK-CTL logic to describe the workflow requirem...

Thanks to its graphical notation and simplicity, Unified Modeling Language (UML) is a de facto standard and a widespread language used in both industry and academia, despite the fact that its semantics is still informal. The Interaction Overview Diagram (IOD) is introduced in UML2; it allows the specification of the behavior in the hierarchical way. In this paper, we make a contribution towards...

Computation of enabled transition instances is a key but difficult problem of animation of colored Petri nets. To address it in our colored Petri net tool, we give an algorithm for computing enabled transition instances. This algorithm is based on pattern matching. So it first tries to bind tokens to variables covered by patterns. If some variables are not covered by any pattern, the algorithm ...
