Location, deployment and counter-deployment of units in military exercises based on bi-level mathematical programming approach

The armed forces of each country, must always be prepared to deal with the enemy's invasion. For this reason, they must maintain their combat readiness by conducting military exercises. Military exercises are the best military exercises to deal with war conditions. A military exercise is conducted in a specific process and with presence of various military units in a specific territorial area. The goal of military exercises is to achieve educational goals at high levels with the maximum presence of all types of military forces. In this research, the problem of locating military units in the ground of exercise and the problem of deployment and counter-deployment in format of bi-level mathematical program are discussed. In this research, the Regional Headquarters is considered as the first level (leader) and the participating units (brigades) in exercise as the second level (follower), regarding that more than one unit is participating in the exercise, we deal with a multi-follower problem. The results of modeling and solving the model showed that if the principles used in this paper were used, selecting the appropriate place to conduct and selecting the appropriate place for each participant in the resume was done more desirable and more scientifically. Also, deployment and counter-deployment of the military equipment and military forces will be done With better control and time management, and if necessary, outsourcing will take place. Therefore, the use of scientific solutions in logistics planning is recommended.
