Getting spare parts where they need to go in a quick, reliable way is a logistical challenge for military and industrial supply chains. Researchers from the U.S. Military Academy at West Point and North Carolina State University have developed a computational model to help determine how best to incorporate additive manufacturing (AM) technologies into these spare parts supply chains.

AM technologies, or “3D printers,” hold tremendous potential for alleviating some of the logistical challenges associated with providing spare parts when and where they are needed. However, AM technologies can be expensive and tricky to transport. They also require personnel who have specialized training. What’s more, spare parts supply chains can be particularly complicated, because there is usually intermittent demand – meaning you likely don’t know when you’ll need to provide a particular part or how many parts might be needed at any point in time.
