We consider the work flow in a medical teaching facility, examining the process that involves an initial patient exam by a resident physician, a subsequent conference between the resident and the attending physician, and the attending physician’s visit with the patient. We create an analytical...

We model a system which consists of a stream of customers processed through three steps by two resources. The first resource, an investigator, handles the first step, in which she collects information from the customer and decides what work will be done in the second step by the second resource,...

The coordination of activities in a work context has been examined by many disciplines and in recent years the role of information systems and other artifacts has become increasingly prominent. The emergency department (ED) of a hospital in a large US city is used to study how information...

Purpose: To demonstrate a simple mathematical model for evaluating operational decisions for preparing compounded sterile products in a hospital pharmacy.Summary: This paper describes a simple mathematical model, based on a small set of parameters easily estimated from existing data. This model...

We consider the problem of scheduling a project when there is an adversary from whom you want to conceal the project’s progress. Interfering with the progress by the adversary is called interdiction. Interdiction may involve hiring away key employees, campaigning for a change in zoning laws,...

We consider a retailer who has two suppliers: one who is RFID enabled and another who is not. Assuming vendor managed inventory (VMI), we address the problem of allocation and pricing of the retail shelf-space. Modeling the problem as a Stackelberg game where the retailer is the leader, we...

In durable goods markets, such as those for automobiles or computers, the coexistence of selling and leasing is common as is the existence of both corporate and individual consumers. Leases to the corporate consumers affect the price of used goods on the second-hand market which in turn affect...
