Decision making in today?s social and business environment has become a complex task. High costs of technology, material, labor, competitive pressures, different economic, social as well as political factors and view points, greatly increase the difficulty of managerial decision making. For well handling of arising problem the decision maker must examine a problem from both qualitative as well as quantitative approach. In today?s global era Operations Research tools can help the decision maker to solve the arising problem. Operations Research represents the study of optimal resource allocation. In order to make the effective and efficient decisions, managers must have fundamental understanding of the decision science tools utilized in developing set of recommendations to choose from. The Operations research is usually the mathematical treatment, analysis of a process, problem, or Operations to determine its purpose and effectiveness and to gain maximum efficiency. Quantitative methods which comprises of Simulation, Linear and nonlinear programming, Queuing Theory and Stochastic Modeling are well-accepted techniques by both research and practice communities. Project scheduling techniques: PERT and CPM are efficient tools for scheduling and monitoring lengthy, complex and expensive projects of that time. This research Paper focuses mainly on the process of Operations research and explains some of the applications of Operations Research, elaborates some of the applications and benefits that may be gained by incorporating Operations Research into the actual business framework. The__ampersandsignnbsp; researcher has a wide interest in the foresaid topic andtheir further research area is the same.
