    Quantum non-locality is a necessary resource for quantum information processing. Recently, I3322 inequality, used as a powerful tool for judging non-locality, has attracted much attention. Considering the non-ideal factors in judging non-locality, MATLAB is used to simulate the quantum violation of inequality influenced by an entanglement state, mixed entanglement states, and noise channels. Results show that for an entanglement state, quantum violation is found when the degree of entanglement is larger than a threshold value. For mixed entanglement states, quantum violation is found in larger parameter regions. Under two-Kraus-operator channels, phase diagram relating to quantum violation is found in the noise parameter space. The results are useful to quantum information processing based on I3322 inequality.
