A matrix diagram consists of a grid with four or more quadrants, each representing a different level of risk exposure. For example, a common matrix diagram has four quadrants: low, medium, high ...

The solution of a generalized stochastic Petri net (GSPN) is severely restricted by the size of its underlying continuous-time Markov chain. In recent work (G. Ciardo and A.S. Miner, 1999), matrix ...

Our compositional lumping approach is complementary to other known model-level lumping approaches for matrix diagrams. The approach has been implemented, and we demonstrate its efficiency and benefits ...
