Operations research (also referred to as decision science , or management science ) is an interdisciplinary mathematical science that focuses on the effective use of technology by organizations. In contrast, many other science & engineering disciplines focus on technology giving secondary considerations to its use. Employing techniques from other mathematical sciences — such as mathematical modeling, statistical analysis, and mathematical optimization — operations research arrives at optimal or near-optimal solutions to complex decision-making problems. Operations Research is often concerned with determining the maximum (of profit, performance, or yield) or minimum (of loss, risk, or cost) of some real-world objective. Operational research encompasses a wide range of problem-solving techniques and methods applied in the pursuit of improved decision-making and efficiency. Some of the tools used by operational researchers are statistics, optimization, probability theory, queui

What is operations research? Explain the scope of OR.                                    [3] List the phases of OR and explain them.                                                           [3] Discuss the guideline of formulation of Linear Programming model and for         converting it into standard form?                                                                          [3]      Define the following:                                                                                         [3]             a.  Optimal solution.                    b. Unbounded solution. c.   Artificial variable.       5. A paper mill produces 2 grades of paper namely X and Y. Because of raw  material restrictions, it cannot produce more than 400 tonnes of grade X and 300            tonnes of grade Y in a week. There are 160 production hours in a week. It requires 0.2 and 0.4 hours to produce a ton of products X and Y respectively with corresponding profits of Rs.2

One of the major one in   India is  Operational Research Society of India. I t  was  founded in 1957 to provide a forum for the Operational Research Scientists as  well as an avenue to widen their horizon by exchange  of knowledge and application of techniques from outside the country.  To further that end, the Society is affiliated to the International  Federation of Operational Research Societies (IFORS). The  headquarters  of the Society is located in Kolkata at 39,  Mahanirvan Road , Kolkata 700029, India . At present the Society has  twelve operating chapters  located in  Agra , Ahmedabad ,  Ajmer ,  Bangalore ,  Chennai ,  Delhi ,  Durgapur ,  Jamshedpur ,  Kolkata ,  Madurai , Mumbai  and  Tirupati . The objectives of  the Society comprise advancement of, conducting of research in, study of,  promotion and propagation of knowledge in Operational Research and  allied techniques through exchange of information, establishment and  maintenance of professional and academic stand
