Abstract: Grey emergency command system that contains randomness, fuzziness, certainties, uncertainties and incompleteness. This paper, for the purpose of an optimal contingency plan, uses gray correlation analysis of the emergency response command system indexes for data analysis. It first defines the gray correlation analysis method to calculate the best assessment of each of emergency index vector sequence, then builds a system of gray correlation matrix to calculate the weight value of each index, and finally gets an effect level gray correlation and contingency plan through calculation to design an optimal contingency plan, which can play a decisionmaking role in planning a more objective and reasonable emergency command system.

Key words: gray correlation; emergency command; correlation matrix; decision
