Defense operations — In modern warfare, the three major military components namely: Air Force. Army and Navy carry out the defense operations. The activities in each of these components can be further divided in four sub-components – administration, Intelligence, operations, training and supply. The applications of modern warfare techniques in each of the components of military organizations require expert knowledge in respective fields. Furthermore, each component works to drive maximum gains from its operations and there always a Possibility that the strategy beneficial to one component may be unfeasible for another component. Thus in defense operation, there is a requirement to coordinate the activities of various components gives maximum benefit to the organization as a whole, having maximum use of the individual components. A team of scientists from various disciplines gets together to study the strategies of different components. After appropriate analysis of the various courses of actions, the team selects the best course of action, known as the ‘optimum strategy’.
In industry— The system of modern industries is so complex that an individual cannot intuitively judge the optimum point Of operation in its various components. The business environment is always changing and any decision useful at one time may not be suitable some time later. There is always a need to check the validity of decisions continuously against the situations. Planning — 0 modern times, it has become necessary for every government to carefully plan, for the economic development of the country OR techniques can be fruitfully applied to maximize the per capita income, with minimum sacrifice and time. A government can thus use OR for framing future economic and social policies.
Agriculture — with increase in population there is a need to increase agriculture output. However, this cannot be done arbitrarily. There are several restrictions. Hence, the need to determine a course of action that serves the best under the given restrictions. We can solve this problem by applying OR techniques.
In hospitals – OR methods can solve waiting problems in outpatient department of big hospitals and administrative problems of the hospital organizations.
In transport – Different OR methods can be applied to regulate the arrival of trains and processing times, to minimize the passengers waiting time and reduce congestion, and to formulate suitable transportation policy, thereby reducing the costs and time of trans-shipment
Research and development – OR methodologies can be applied in the field of research and development for several purposes, such as to control and plan product introductions.
