My research is motivated by the supply chain management of defense operations, namely the supply strategies employed by military organizations, typically Ministries of Defense, to maintain equipment in mission areas. Traditionally, this is achieved by keeping in the base a spare parts inventory, which is periodically replenished. Alternatively to traditional manufacturing and shipment of spare parts, military organizations may deploy a 3D-printer on site to secure necessary replacements faster, but this is practicable only when in possession of the corresponding intellectual property rights, which are granted by the original manufacturer after purchasing a license. Offering the digital license comes with high setup costs for the intellectual property owner, which may then be reluctant to provide it. The scope of this project is to study the interactions between ministries of defense as well as intellectual property owners, where the former aim to enable the digital channel, and reap its benefits. Using tools of game theory and operations research, we aim for theoretical results explaining cooperation among military organizations and the interaction between the decisions of relevant parties. Results may lead to novel supply strategies to incorporate 3D-printing in supply chain management, enabling military organizations to exploit the advantages of this technology.
