relationship between operation research and computer science

As others have pointed out, the bulk of Operations Research is relationship between inputs and outputs; Data Science is where you turn if. Under a broad definition of Computer Science (below), Operations Research can be considered a sub-field. CS and OR are much more intertwined than many. Department of Operations Research in practice are those where there is a correlation between periods or stages (such as correlation.

How Operations Research and Artificial Intelligence Overlap

UPS does this calculation thousands of times per day An airport hub shuts down due to a storm — all flights in and out are canceled. Rearrange the flights of all planes in your airline to get as many passengers as possible to their destinations. You have 20 minutes. Continental Airlines built such a system Schedule all baseball games for a season.

Flying teams around costs thousands of dollars per hour, so make the schedule that minimizes the cost spent on travel. Soft AI is purpose-built software that exhibits intelligence, but only in one specific area. An example is a computer that plays chess — it is quit efficient at playing chess, but cannot also play checkers. Hard AI aims to replicate human thought patterns using techniques like neural networks.

The same learning can also allow Google Brain to identify babies or motorcycles. Since that time, operational research has expanded into a field widely used in industries ranging from petrochemicals to airlines, finance, logistics, and government, moving to a focus on the development of mathematical models that can be used to analyse and optimize complex systems, and has become an area of active academic and industrial research.

Others in the 18th and 19th centuries solved these types of problems with combinatorics. Charles Babbage 's research into the cost of transportation and sorting of mail led to England's universal "Penny Post" inand studies into the dynamical behaviour of railway vehicles in defence of the GWR 's broad gauge.

Operational research may have originated in the efforts of military planners during World War I convoy theory and Lanchester's laws. Percy Bridgman brought operational research to bear on problems in physics in the s and would later attempt to extend these to the social sciences.

Rowe conceived the idea as a means to analyse and improve the working of the UK's early warning radar system, Chain Home CH. Initially, he analysed the operating of the radar equipment and its communication networks, expanding later to include the operating personnel's behaviour.

This revealed unappreciated limitations of the CH network and allowed remedial action to be taken. In the World War II era, operational research was defined as "a scientific method of providing executive departments with a quantitative basis for decisions regarding the operations under their control".

Early in the war while working for the Royal Aircraft Establishment RAE he set up a team known as the "Circus" which helped to reduce the number of anti-aircraft artillery rounds needed to shoot down an enemy aircraft from an average of over 20, at the start of the Battle of Britain to 4, in Britain introduced the convoy system to reduce shipping losses, but while the principle of using warships to accompany merchant ships was generally accepted, it was unclear whether it was better for convoys to be small or large.

Convoys travel at the speed of the slowest member, so small convoys can travel faster. These systems use the raw usually historical data from data-processing systems to prepare management summaries, to chart information on trends and cycles, and to monitor actual performance against plans or budgets.

More recently, decision support systems DSS have been developed to project and predict the results of decisions before they are made. These projections permit managers and analysts to evaluate the possible consequences of decisions and to try several alternatives on paper before committing valuable resources to actual programs.

The development of management information systems and decision support systems brought operations researchers and industrial engineers to the forefront of business planning.

These computer-based systems require knowledge of an organization and its activities in addition to technical skills in computer programming and data handling. The key issues in MIS or DSS include how a system will be modeled, how the model of the system will be handled by the computer, what data will be used, how far into the future trends will be extrapolatedand so on.

Operations research

In much of this work, as well as in more traditional operations research modeling, simulation techniques have proved invaluable. New software tools for decision making The explosive growth of personal computers in business organizations in the early s spawned a parallel growth in software to assist in decision making.

These tools include spreadsheet programs for analyzing complex problems with trails that have different sets of data, data base management programs that permit the orderly maintenance and manipulation of vast amounts of information, and graphics programs that quickly and easily prepare professional-looking displays of data.

Business programs software like these once cost tens of thousands of dollars; now they are widely available, may be used on relatively inexpensive hardware, are easy to use without learning a programming language, and are powerful enough to handle sophisticated, practical business problems.
