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...

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 revisit the tax-loss selling hypothesis as an explanation of the January effect. We expand on prior empirical evidence from municipal bond closed-end funds (CEFs) by extending the sample period by 19 years and adding exchange-traded funds (ETFs). Our sample covers the introduction and rapid...

We construct a mathematical models to explore why digitization of employee recruiting process so far did not result in employers reporting hiring better candidates faster. We model multidimensional impact of internet technology with increases in the total number of applications, in the rate at...

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...

Most hospitals in the US provide and manage durable surgical instruments used in operating rooms. Instruments are customarily stored and delivered to operating rooms as trays (kits). The advantages of organizing instruments into custom trays have been discussed elsewhere. They include:...

Some potentially dangerous diseases are completely asymptomatic. Their diagnosis as incidental findings of ever more sensitive medical imaging can leave patients and physicians in something of a quandary. The patient feels well and potential interventions to stave off long term deterioration or...

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,...
