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.
