The applicability of queueing network models to real-world systems is often enhanced by characterizing service times using phase-type (PH) distributions. Unfortunately, the combinatorial explosion of the underlying state space makes it difficult to evaluate efficiently the resulting models. We propose to tackle this issue by a solution algorithm inspired by the Reversed Compound Agent Theorem (RCAT).
