LINEAR PROGRAMMING APPLICATIONS – Notes of Operations Research

LINEAR PROGRAMMING APPLICATIONS Linear programming is a powerful quantitative technique (or operational research technique) designs to solve allocation problem. The term ‘linear programming’ consists of the two words ‘Linear’ and ‘Programming’. The word ‘Linear’ is used to describe the relationship between decision variables, which are directly proportional. For example, if doubling (or tripling) the production…

OPERATIONS RESEARCH FOR B.COM, BBA, M.COM & MBA

OPERATIONS RESEARCH Operations research (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. The concept of OR arose during World War II by military planners. After the war,…
