Operations Research - Definition

According to Philip McCord Morse together with George E. Kimball,

"Operations query is a scientific method of providing executive departments alongside a quantitative reason for decisions regarding the operations nether their control."

According to Russell L. Ackoff together with C. West Churchman,

"Operations query is the application of scientific methods to brand it at the optimal solutions to the problems."

Meaning of Operations Research

Operations query OR agency to apply scientific together with mathematical methods for decision making together with work solving.

OR does non furnish decisions else it provides quantitative information to the managers. The managers utilisation this information for making decisions.

OR tries to honour meliorate solutions to unlike problems. Hence, it is used to solve complex management problems.

OR helps to direct keep decisions almost operations together with production.

OR was showtime used during the Second World War yesteryear England to solve their complex state of war problems. England made OR teams. These teams included adept mathematicians, statisticians, scientists, engineers, etc. These OR teams were really successful inward solving England's state of war problems. Therefore, US of America of America (USA) every bit good started using OR to solve their state of war problems. After the war, shortly industries together with businesses every bit good started using OR to solve their complex administration problems.

Features of Operations Research

The principal characteristics or features of operations query (OR) are:-

1. Creating a Model : OR showtime makes a model. Influenza A virus subtype H5N1 model is a logical representation of a problem. It shows the relationships betwixt the unlike variables inward the problem. It is merely similar a mathematical formula.
   For e.g. Assets - Liabilities = Capital + Accumulated Reserves.
2. Shows Important Variables : OR shows the variables which are of import for solving the problem. Many of the variables are uncontrollable.
3. Symbolises the Model : The OR model, its variables together with goals are converted into mathematical symbols. These symbols tin survive easily identified, together with they tin survive used for calculation.
4. Achieving the Goal : The principal destination of OR is to choose the best solution for solving the problem.
5. Quantifying the Model : All variables inward the OR model are quantified. That is, they are converted into numbers. This is because alone quantified information tin survive lay into the model to larn results.
6. Using Mathematical Devices : Data is supplemented alongside mathematical devices to narrow downwards the margin of error.
7. Use of Computer : The principal focus is on decision-making together with work solving. For this move computers are widely used.
8. Interdisciplinary : OR is interdisciplinary, because it uses techniques from economics, mathematics, chemistry, physics, etc.
9. Highest Efficiency : The principal aim of OR is to brand decisions together with solve problems. This results inward the highest possible efficiency.

Limitations of Operations Research

The demerits or limitations of operations query (OR) are depicted below.

1. Costly : Operations Research (OR) is really costly. This is because OR makes mathematical models for taking decisions together with solving problems. The fellowship has to brand diverse models for solving unlike problems. All this increments the cost.
2. Not Realistic : OR experts brand really complex models for solving problems. These models may non survive realistic. Hence, they may non survive useful for real-life situations.
3. Complex : OR is really complex concept. It is really hard for an average managing director to sympathise it. Therefore, most managers exercise non utilisation OR techniques.
