Split and merge into it. The phases of OR are 1 Observe the problem environment 2 Analyse and define the problem 3 Develop a model 4 Selection of data input 5 solution and testing 6 Implementation of the solution In detail Step I. Observe the Problem Environment The first step of OR study is the observation of the environment in which the problem exists. The activities that constitute this step are visits, conferences, observations, research etc.
Analyse and Define the Problem In this step not only the problem is defined but also uses, objectives and limitations of the study that are stressed in the light of the problem. The end results of this step are clear grasp of need for a solution and understanding of its nature. Develop a Model The next step is to develop model, which is representation of same real or abstract situation. OR models are basically mathematical models representing systems, process or environment in form of equations, relationships or formulae.
The activities in this step is to defining interrelationships among variables, formulating equations, using known OR models or searching suitable alternate models. The proposed model may be field tested and modified in order to work under stated environmental constraints.
A model may also be modified if the management is not satisfied with the answer that it gives. Selection of Data Input It is a established fact that without authentic and appropriate data the results of the OR models cannot be trusted. Hence, taping right kind of data is a vital step in OR process. Important activities in this step are analysing internal-external data and facts, collecting opinions and using computer data banks.
The purpose of this step is to have sufficient input to operate and test the model. Solution and Testing In this step the solution of the problems is obtained with the help of model and data input.
Such a solution is not implemented immediately and this solution is used to test the model and to find its limitations if any. If the solution is not reasonable or if the model is not behaving properly, updating and modification of the model is considered at this stage. The end result of this step is solution that is desirable and supports current organisational objectives.
Implementation of the Solution This is the last phase of the OR study. In OR the decision-making is scientific but implementation of decision involves many behavioural issues. Therefore, implementation authority has to resolve the behavioural issues, involving the workers and supervisors to avoid further conflicts. The gap between management and OR scientist may offer some resistance but must be eliminated before solution is accepted in totality. Both the parties should play positive role, since the implementation will help the organisation as a whole.
A properly implemented solution obtained through OR techniques results in improved working conditions and wins management support. What is operational research? Applied research is designed to solve practical problems of the modern world, rather than to aqcquire knowledge for knowledge's sake. One might say that the goal of the applied scientist is to improve the human condition.
What are the applications of operations research? Operational Research as it was originally called and is still known by that name in Europe is a very broad canvas and the applications are exceptionally varied. Can a three phase motor be rewired for single phase operation?
Of course, but it will change all parameters HP, torque etc. The problem is someone would have to redesign of that motor,. Basically, is not worth it. What are the scope and methodology of operational research explaining the stages phase? What are the Roles of operational research in business problems? Operational research would provide information regarding the day to day operations of the business, with the goal of highlighting or preventing problems in that area.
It is more of an internal search for the answers, as opposed to looking at the Marketing Sales , or production areas. Significance of operation research? Operational research will help managers determine best practiceswithin their industry. Many businesses use operations research tochange their position in their industry. What is the importance of operation research in business decision? Operations research helps a business to make decisions regardingcrucial aspects like cues or the order of production of certainmaterials.
The analytical methods applied aid in industrialproduction and wartime planning. What are the Applications of operations research in accounting? Scope of operational research?
Operational research will help businesses improve their businessoperations. Researching efficient business operations will improvethe business's performance within the industry. What is difference between Operations Research and Operational Research? Theformer is a term representing a subject of research, the later isshowing the status of research. Application of operation research? Applications of OR 1. Finance and Accounting 2. Purchasing,Procurement and Exploitation 5.
Techniques and General Management 7. What is Importance of operations research in decision making? Operations research is a scientific discipline that managers use to make informed decisions for their operations. It draws heavily from math, statistics and science.
Operations managers use this extensively to schedule and assemble their production functions. Operations research is primarily used in the manufacturing, oil, energy and telecommunication industries..
Operations research was first developed in the s, during and after World War II. Companies use operations research to devise ways and means to maximize their profits and restrict their losses and risks.
The company is able to zero down on the most optimum levels of production. Also, they devise means to produce at lower costs or produce more quantities at the same costs.
The operations manager is able to evaluate the various available routes for production and fix the most feasible and practical one. He tries to derive the maximum output with the minimum possible input. Operations research is very beneficial to the managers in deciding what to produce, the quantities, the methods of production, which employees to engage in the production processes and the marketing schemes of the produced goods.
The main limitation of operations research is that it often ignores the human element in the production process. This science is technology driven and does not take into account the emotional factors and absenteeism of the employees.
What is the difference between operations research and operations management? Operation management is concerns management of production transformation system, system design, operation, improvement, systematic analysis of organizational process. The principles of modelling in operations research? What is the scope and limitation of operation research? Operations Research OR is very costly. This is because OR makes mathematical models for taking decisions and solving problems.
The company has to make various models for solving different problems. It may be pointed out that he should specify that condition under which the solution can be utilized.
He should also point out weaknesses if any so that management will know what risks they are taking while employing the model to generate results. Thus he should also specify the limits with in which the results obtained from using the model are valid.
He should also define those conditions under which the model will not work. The last phase of the operation research methodology is implementation of solutions obtained in the previous steps.
In operation research though decision making is scientific but its implementation involves so many behavioral issues. Therefore the implementing authority has to resolve the behavioral issues. He has to sell the idea of utility of O. R not only to the workers but also to superiors. The distance between O. A properly implemented solution obtained through application of O.

The distinctive approach is to develop a scientific model of the system incorporating measurement of factors such as chance and risk, to predict and compare the outcome of alternative decisions, strategies or controls. In fact in Operation Research, research techniques and scientific methods are employed for the analysis and also for studying the current or future problems.
Thus, Operation Research offers alternative plans for a problem to the management for decisions. Problems dealing with production processing i. But it may be remembered that operation research never replaces a manager as decision maker. The ultimate and full responsibility for analysing all factors and making decision will be of the manager. In the more wide sense, operation research does not deal with the everyday problems such as output by the one worker or machine capacity; instead it is concerned with the overall aspect of business operation such as something as the relationship between inventory, sales, production and scheduling.
It may also deal with the overall flow of goods and services from plants to consumers. The team doing operation research may have statisticians, psychologists, labour specialists, mathematicians and others depending upon the requirement for the problems. Now our aim is to learn how we can have better decisions. The procedure for making decisions with the OR study generally involves the following phases: Without OR, in many cases, we follow these phases in full, but in other cases, we leave important steps out.
Judgment and subjective decision-making are not good enough. Thus industries look to operation research for more objective way to make decisions. It is found that method used should consider the emotional and subjective factors also.
For example, the skill and creative labour are important factors in our business and if management wants to have a new location, the management has to consider the personal feeling of the employees for the location which he chooses.
In its recent years of organised development, O. So there is a great scope for economist, statisticians, administrators, politicians and technicians working in a team to solve this problem by an O.
On the other hand, with the explosion of population and consequent shortage of food, every country is facing the problem of optimum allocation of land for various crops in accordance with climatic conditions and available facilities. The problem of optimal distribution of water from a resource like a canal for irrigation purposes is faced by developing country. Hence a good amount of scientific work can be done in this direction.
Management is always interested in optimizing profits. Hence in order to provide decision on scientific basis, O. Operation research approach helps in operation management. Operation management can be defined as the management of systems for providing goods or services, and is concerned with the design and operation of systems for the manufacture, transport, supply or service.
Following are the six phases and processes of operational research: Formulate the problem: This is the most important process, it is generally lengthy and time consuming. The activities that constitute this step are visits, observations, research, etc.
In an operational research project there are 5 phases, namely, problem identification, formulating problem, deriving solution validating model and lastly, the implementation of results. The first phase is to identify the problem through the observation of its symptoms if it is not obvious.
