These are stockpile calculations based on the finite life of weapons in combat, the number of weapon systems, the average number of engagements, and the sum of the expanded munitions fired by the weapon systems during their engagements until they are destroyed. The stockpile calculations are based on an agreed mathematical model in order to defeat a finite, assessed number of targets. It uses mathematical programming models to assist the military planner in determining the optimal acquisition of equipment and ammunition. National concepts of operations and the acquisition policies are part of the optimisation process. Data describing the forces is based on the national DPQ replies.
Technical data is compiled and verified twice annually.
Mission data is based on the Defence Requirements Review studies which also form the basis for the NATO Force Planning. The optimisation models interface directly with the database. The common database will also serve the future Logistics Reporting System. Bi-MNC Stockpile Guidance 409. Stockpile requirements for munitions are determined by MNCs in consultation with the countries using threat or target related calculation methodologies.
