Group decision making is one of the most effective methods to resolve complex decision problems. In this paper, it was proved that both the weighted geometric mean complex judgement and the weighted arithmetical mean complex judgement will converge in probability at impersonal priority vector if the perturbation factors in judgements that experts given is stochastic. This result is of importance to group decision making.
