Programmes Decisions:. The distance between O.R scientist and management may create huddles thus the gap between one who provides a solution and the other who wants to utilize it must be eliminated. Operations Research is a bouquet of mathematical techniques that have evolved over the last six decades to improve the process of business deci- sion making. The data collection can clearly effect the models output significantly. The next phase for the operation researcher is to explain his findings to the management. Today, operations research is a mature, well-developed field with a sophisticated array of techniques that are used routinely to solve problems in a wide range of application areas. In operations research, problems are broken down into basic components and then solved in defined steps by mathematical analysis. For a better understanding, the following example shows a practical application of operations research techniques. No model will work appropriately if the data is not appropriate. A solution may be extracted from a model either by conducting experiments on it i.e., by simulation or by mathematical analysis. In particular, operational analysis forms part of the Combined Operational Effectiveness and Investment Appraisals, which support British defence ca Waiting line theory or queuing theory. To achieve this both the management and O.R scientist should play positive role A properly implemented solution obtained through application of O.R techniques results in improved working conditions and gains the management support.
