The Signed Directed Graph (SDG) can describe the complicated cause and effect relation and contain mass underlying information. Qualitative simulation can also help to analyze the reason for leading abnormity of material supply process and the result brought by the abnormity. The principle of the qualitative simulation based on the SDG was researched; the qualitative models were founded using the simulation tool, the reason and result paths were got; the efficiency evaluation method using material supply process qualitative simulation was brought out; the strongpoint and shortcoming of SDG was analyzed.
