Operations Research Lecture Notes
Operations Research • • • • • Some important tips before start of course material to students Mostly we followed Book by S D Sharma, as prescribed for this syllabus At places, we use some internet links not necessarily mentioned there at. We acknowledge all such resources. As the course is mostly mathematical in nature, we will be solving problems in class room. The problems will involve a lot of mathematics, calculations although simple but will be so time consuming to express on computers, we leave it up to students to ask in details any particular topic or problem in class or during contact hours. So ready to take off !!!!
History of Operations Research The term Operation Research has its origin during the Second World War. The military management of England called a team of scientists to study the strategic and tactical problems which could raise in air and land defence of the country. As the resources were limited and those need to be fully but properly utilized. The team did not involve actually in military operations like fight or attending war but the team kept off the war but studying and suggesting various operations related to war.
What is Operations Research? Several definitions have been given • Operations research (abbreviated as OR hereafter) is a scientific method of providing executive departments with a quantitative basis for decisions regarding the operations under their control: Morse and Kimbal (1944) • OR is an analytical method of problem-solving and decision-making that is useful in the management of organizations. In operations research, problems are broken down into basic components and then solved in defined steps by mathematical analysis. • Operational Research (OR) is the use of advanced analytical techniques to improve decision making. It is sometimes known as Operations Research, Management Science or Industrial Engineering. People with skills in OR hold jobs in decision support, business analytics, marketing analysis and logistics planning – as well as jobs with OR in the title. •As such a number of definitions can be found in literature, you can express the term OR with the spirit mentioned in the literature.
