We consider an assembly system with multiple stages, multiple items, and multiple customer classes. The system consists of m production facilities, each producing a different item. Items are produced in variable batch sizes, one batch at a time, with exponentially distributed batch production...

We consider a production-inventory system with two customer classes, one patient and one impatient. Orders from the patient class can be back-ordered if needed while orders from the impatient class must be rejected if they cannot be fulfilled from on-hand inventory. Orders back-ordered incur a...

We consider the problem of optimal fleet sizing in a vehicle sharing system. Vehicles are available for short-term rental and are accessible from multiple locations. A vehicle rented at one location can be returned to any other location. The size of the fleet must account not only for the...

On-demand service platforms compete for both workers and customers, forming a two-sided competition. In this paper, we study the game between two platforms implied by such a two-sided competition and examine how the characteristics of the embedded workers-customers subgame affect outcomes in...

Problem Definition: An on-demand service platform relies on independent workers (agents) who decide how much time, if any, to devote to the platform. Some labor advocates have argued that an expansion of the labor pool hurts agents—by reducing the wage and agent utilization (i.e., the fraction...

Problem Definition:End-consumers pay substantial price premia for green certified sustainably sourced products. In addition to the cost of sustainable practices themselves, record keeping required to keep track of those practices and auditing by certifying agencies are costly for the supplier....

We consider the problem of allocating demand arising from multiple products to multiple production facilities with finite capacity and load-dependent lead-times. Production facilities can choose to manufacture items either to-stock or to-order. Products vary in their demand rates, holding and...

The sharing economy, a term we use to refer to business models built around on-demand access to products and services mediated by online platforms that match many small suppliers or service providers to many small buyers, has emerged as an important area of study in operations management. We...

It is widely believed that ride sharing, the practice of sharing a car such that more than one person travels in the car during a journey, has the potential to significantly reduce traffic by filling up cars more efficiently. We introduce a model in which individuals may share rides for a...
