We consider a supply chain where multiple suppliers and a manufacturer contribute to the assembly of a product (through providing components or labor). The product fails if any of its components (or elements of work) fails, but finding the faulty component can be prohibitively difficult. We...

We consider the production and admission control of a two-stage manufacturing system where intermediate components are produced to stock in the first stage and an end-product is assembled from these components through a second stage assembly operation which may allow backorders. The...

We consider the joint optimization of ordering and upgrading decisions in a dynamic multiproduct system over a finite time horizon of $T$ periods. Multiple classes of demand arrive in each period stochastically following stationary distributions. Demand can be satisfied with supply of the same...

Firms that offer multiple products are often susceptible to periods of inventory mismatches where one product may face shortages while the other has excess inventories. In this paper, we study a joint implementation of price- and capacity-based substitution mechanisms to alleviate the level of...

We consider the problem of allocating a single server to a system of queues with Poisson arrivals. Each queue represents a class of jobs and possesses a holding cost rate, general service distribution, and general set-up time distribution. The objective is to minimize the expected holding cost...
