Military supply chains and closed-loop systems: resource allocation and incentives in supply sourcing and supply chain design

The US military operates some of the largest and most complex supply chains in the world and their experience provides insight into a variety of supply chain issues. This paper taps that experience to study how the design of a supply chain is influenced by its economic environment. Consider these circumstances: the military is not a profit-seeking enterprise, they want to achieve a particular state of readiness and cost is secondary to that goal. Modern weapons systems are complex, expensive, push the envelope of technology, and the volume requisitioned is often small such that few manufacturers can afford to be in the business; and these expensive weapons systems operate in harsh operating conditions where wear and tear is substantial, consequently remanufacturing of systems and parts is a critical source of supply. Focusing on the supply chain of the US Army, this paper uses an economic model to study their responses to these conditions, how supply chain design is affected by these conflicting goals, and how those designs affect cost and efficiency.
