With the wide application of probabilistic systems, the research of counterexample generation for probabilistic system with model checking has attracted wide attention. For counterexample of complex parametric system, proposes a counterexample generation algorithm for multiple until constraint formulae of probabilistic computation tree logic act on continuous time probabilistic model and gives another counterexample computation method based on automaton theory. At last, the example analysis is given. The theoretical analysis and example result show that the feasibility and validity of the method.
