Threat evaluation model of targets based on information entropy and fuzzy optimization theory

To provide practical decision-makings for fire-target assignment of missile ground-to-air weapon system in anti-air warfare, a threat evaluation model based on information entropy and fuzzy optimization theory was studied. Firstly, information entropy theory was used to calculate the entropy weight of each evaluation index, and the importance weight of each index was also included, the entropy weight and the importance weight of each index were integrated to gain the final weight; Then, the fuzzy optimization theory was used to establish the threat evaluation model; Finally, the validity of the model was illustrated by a practical example.
