Abstract: Both stochastic dynamics and bullwhip effect increase the robust difficulty of supply chain systems modeling, and supply chain running smoothly is the important foundation of supply chain management.Aiming at supply chain with grey stochastic dynamic characteristic, based on linear time-invariant systems, Markov algorithm is used to resolve the robustness of stochastic jump linear systems in the supply chain systems, and an effective measuring index that predicates the robustness is obtained.The numerical result verifies: the bullwhip effect magnitude of the stochastic chain is hardly related to the magnitude of either of the two modes, nor the long-term average; the performance of Markovian jump linear systems should not be simply predicted from the performance of its individual modes; uncertainty operations should degrade system performance.
