Distribution problems are not restricted to the shipment of discrete units; consider the flow and pricing of electricity, oil, natural gas, or electronic funds. Private and Public Services The key distinction between services and physical products is that services are usually produced and consumed at the same time.

Customer satisfaction, often determined by the experience of waiting Larson, along with the price of service, is a key objective in managing service operations Wright and Race, Determining the appropriate service capacity e.

In the public sector, operations researchers have devoted considerable attention to the study and improvement of emergency services, including police Larson,fire Walker et al. Additional public-sector applications include the criminal justice system, public transportation, energy, and the environment Pollock et al.

In the private sector, the real-time pricing of services, known as yield or revenue management, is another aspect of services management where OR has had a major impact. Revenue management methods are employed routinely in the airline, hotel, and car rental industries, among others Talluri and van Ryzin, Medicine and Public Health Along with scholars and practitioners from many other academic disciplines, operations researchers have focused attention on different aspects of health care in recent years.

The focus on the operations involved in delivering healthcare services is what distinguishes OR from other studies.

Operations Management This discipline covers not only manufacturing processes, but support processes that add value to the product or service as well as the management of the entire supply chain. There are a number of ways that organizations can streamline their operations to meet the demands of today's marketplace.
Optimization and Operations Research You can submit a problem in an appropriate framework, and request that a particular algorithm be used to solve the problem. It includes interactive formulations of the diet problem and the portfolio optimization problem.

Needle exchange programs provide an example of this perspective. These controversial programs enable drug injectors to exchange used needles and syringes for clean ones to prevent HIV transmission via needle sharing National Research Council and Institute of Medicine, Although many studies focused on surveys of program clients to determine whether rates of needle sharing declined as a Page 38 Share Cite Suggested Citation: Behavioral and Social Scientific Foundations.

The National Academies Press. Homeland Security and Counterterrorism Since the terrorist attacks of September 11,many operations researchers have turned their attention to problems related to terrorism. Examples include the defense of critical infrastructure such as electricity grids, pipelines, and transportation hubs, including airports and subway stations, chemical plants, nuclear reactors, and major ports.

Models for these scenarios have been developed, and in many cases the recommended courses of action have been adopted Brown et al. Other examples include the operational as opposed to scientific effectiveness of detectors of suicide bombers Kaplan and Kress,evaluation and proposed improvements to US-VISIT the Department of Homeland Security biometric identification program for immigration and border management at U.

Pringle reports several examples, including the following: Further examples of monetary benefits generated by industry OR groups appear in Bell et al. Clearly much can be gained by applying OR ideas in industry.

Leaving to the side purely mathematical studies meant to improve the quantitative methods of OR, the goal of an applied study is to improve decision making. Historically, this has placed OR groups in an advisory role in which responsible decision makers e. This does not imply that problems always arrive as well-posed questions; indeed, Morse and Kimballp.

For example, issues that might be addressed are the basic processes that characterize the flow of material in production processes; the transmission of infections in contagious outbreaks; the routing of Internet traffic; the movement of offenders through the criminal justice system; the generation and distribution of electricity; or the interdiction of terrorists en route to attack.

What part of these processes represents cause for concern e. Such expertise is often best gained via direct observation, which is why operations researchers have been known to ride around in police patrol cars, spend time on factory floors or in warehouses, or observe the formation and dissipation of lines at banks, on highways, in call centers, or at Disney World.

Another important part of getting started is figuring out just what the decision maker is trying to achieve. What are the objectives? If faced with two ways to implement the operation s in question, could the decision maker state which one is preferred and why?

Getting decision makers to explicitly state their objectives in terms of performance measures represents a major step toward understanding the problem see Fischhoff, this volume, Chapter With a common understanding of objectives and performance measures, problem identification becomes much easier.

The hallmark of an OR study is the creation of a mathematical model that represents the operations of the system under study, and the choices and alternatives available to the decision maker, and that situates both within the appropriate environment.

Crafting a model is a creative act that is as much art as science. The relationship between observation and data collection on the one hand and model development on the other is bidirectional, in that the model can suggest new data to collect as easily as field observation can cause revision or abandonment of the model in question.

Most OR students are familiar with mathematical problem sets meant to drill and further teach the nuances of the modeling methods under study.

For an empirical study of how operations modelers approach problems and formulate new models, see Willemain All of these methods have and continue to be used in applications such as those outlined earlier. Although the interested reader can learn the basics of these methods from any good introductory textbook in operations research e.

Optimization problems involve the maximization or minimization of some objective function e. The techniques used to solve optimization problems depend on the underlying mathematical specifics e. The solution to an optimization problem identifies the values of the decision variables that lead to the best outcome for the decision maker within the assumptions of the model, along with the value of that outcome e.Operations research and computers interact in many scientific fields of vital importance to our society.
