This process is used in situations where various states are defined and the system moves from one state to another on a probability basis. 3 MODELS AND PROBABILITY Ways to study a system Figure 2.—Operations research experts can study actual systems, but usually use models instead (Source: … Limitations of Operations Research. 1 3 In this regard, Microsoft unveiled a speech … In one phase of decision making viz., selection of best solution through the evaluation of alternatives, operations research comes into the picture. With deduction one moves directly from the model to a solution in either symbolic or numerical form. I remember that this was not a trivial task (it should have been). Operations Research are the disciplines that deal with such problems on a scientific basis; that is, they apply scientific methods and information technology to problem solving and provide the problem owner with quantitative approaches to informed and rational decision-making. 2, May 2009, pp. Operations research is about the application of advanced analytical methods to help make better decisions, 2 and the operations research models adopted in those reviewed papers range from various programming models and stochastic optimization to game theoretical models.
