Aiming at the vague packaging air transportability evaluation of the cartridge military hazardous materials, the packaging air transportability evaluation of the cartridge military hazardous materials is evaluated based on entropy-G1 method. Firstly, the evaluation index system is built based on the influencing factors of the packaging air transportability of the cartridge military hazardous materials. Secondly, for the uncertainty of the index, based on grey incidence decision-making theory, grey evaluation model of the packaging air transportability of the cartridge military hazardous materials is built. The combination weight is ensured by using the method of combining entropy and G1 to make the weight more reasonable. Finally, carry out example test. The result shows that this evaluation model is valid and practical, with solving the question of the packaging air transportability evaluation of the cartridge military hazardous materials, and providing a referential model for the army.
