We consider a supply network where a retailer sources from multiple economically weaker suppliers for a high-quality key material. The production of the material needs to comply with social and environmental standards over time. However, such compliance is costly, and the cost varies with...

Stockpiling inventory is an essential strategy for building supply chain resilience. It enables firms to continue operating while finding a solution to an unexpected event that causes a supply disruption or demand surge. While extremely valuable when actually deployed, stockpiles incur large...

We consider a capacity provider and a group of independent buyers who partner to share a scarce but expensive-to-build capacity over a finite horizon under privately informed demand conditions. At the beginning of the time horizon, the capacity provider must invest in building capacity; all...

In the wake of the COVID-19 pandemic, severe economic damage and product shortages caused by demand surges and supply disruptions have prompted interests in strategies and tools for building resilient supply chains. The recent geopolitical conflicts as well as increased frequency of natural...

We consider a make-to-stock, finite-capacity production system with setup cost and delay-sensitive customers. To balance the setup and inventory related costs, the production manager adopts a two-critical-number control policy, where the production starts when the number of waiting customers...

In today's increasingly globalized environment, more and more companies recognize the mutual dependence of supply chain partners in value creation. When making business decisions, they take into consideration their partners' bottom line profitability, especially in emerging markets. The question...

We present a general framework to study the design of spare parts logistics in the presence of 3D printing technology. We consider multiple parts facing stochastic demands, and adopt procure/manufacture-to-stock versus print-on-demand to highlight the main difference of production modes featured...

Additive manufacturing (AM), also known as 3D printing, has the potential to shift supply chains from global networks that rely on centralized production with traditional manufacturing technologies to largely digital networks with decentralized, local 3D printing, i.e., digital inventory. One...
