The Mobius modeling environment: Recent developments

The Mobius modeling tool provides an infrastructure to support multiple interacting formalisms and solvers, and is extensible in that new formalisms and solvers can be added to the tool in such a way that they can interact with those already implemented without requiring additional changes to the previously implemented ones. We have continued to add features to the Mobius tool in order to enhance the extensibility of the tool and to allow increased interaction between new and different formalisms and solvers. In this paper we discuss some recent additions to Mobius, including expanded state variable types, a fixed-point mechanism called "connection," and improvements to CTMC solution that includes a new state level abstract functional interface.
