Operations Research (OR) helps the managers to take better and quicker decisions. Look, it is extremely difficult to describe all possible types of research limitations. Although complex problems are fit for analysis by tools of operations research, relatively simple problems have no economic justification for this type of quantitative analysis. But it is still the major reasons why firms are slow to use operations research. A final drawback of operations research at least in its application to complex problems is that analyses and programming are expensive and many problems are not important enough to justify this cost. However, in practice this has not really been a major limitation. Thus there is a gap between

However, it is critically important for you to be striving to minimize the range of scope of limitations throughout the research process. What is Operations Research in management? In its essence, an operation research (OR), is the branch of applied mathematics that deals with optimizing the use of available resources, given limitations and constraints. The major limitations of the operations research profession itself are: (a) The mind-set of the operations research analyst to be suspicious of the human ser- vices characteristic of any profession grounded in quantitative analysis based on an available body of "hard" data. These are applicable to only specific categories of decision-making problems. I guess the next question would be: which limitations should I mention? A key objective of the research process is not only discovering new knowledge but also to confront assumptions and explore what we don't know. Finance, Budgeting and Investment: i. Which of the following is not the phase of OR methodology? Simulation generates a way of evaluating solutions but does not generate solutions themselves. account the complexities of human relations and behaviour. 5 important Limitation of Operations Research: There are a number of limitations of operations research which may be stated as follows: 1. Operations research is not a substitute for the entire process of decision making and it does not relieve the managers of their task of decision making. Related to the fact that many management decisions involve un-measurable factors is the lack of information needed to make operations research useful in practice.

Access-- if your study depends on having access to people, organizations, data, or documents and, for whatever reason, access is denied or limited in some way, the reasons for this needs to be described.Also, include an explanation why being denied or limited access did not prevent you from following through on your study. Implementation of any decision is a delicate task. Managers have to prepare the ground-work for the introduction of operations research through several steps in decision making viz., diagnosis of problem, analysis of problem and development of alternatives; and even after the selection of best solution by operations research, managers have to put the decision into- effect and to institute a system of follow-up. 4. If such estimates are wrong, the result would be- equally misleading. Image Credits © Emir.
