Limitations of Operations Research

Some businesses use research to improvetheir position within the industry. Scope and objectives of business research? Business research is almost always applied research. This means that it is problem-oriented with the objective of obtaining information to help solve a specific business problem or make a decision. Business research tends to have a time limit. It makes little sense to gather information about a decision that was made three weeks ago or to get information next week that we need today.

Information is highly perishable. It gets old and useless very quickly. Like fish, if you don't consume it when fresh, it loses a lot of its flavor-and starts to smell bad! Business research is done in an environment in which conditions change rapidly. The answers to research questions asked today may very well differ from the answers to the same questions obtained yesterday. In those areas where the manager needs to "stay in tune" with the changing landscape, the same research questions might need to be asked repeatedly.

Successful organizations develop a culture where constant research is an integral part of their operation. Scope and limitation of computer addiction? The scope of computer addiction can include missing work, missingschool, and missing out on social functions, due to the time spendon the computer. Limitations could be losing friends because ofyour addiction, and becoming distanced from family.

Example of scope and limitation of the study? The scope of a study is what we can learn from the study. Thelimitation concerns information we cannot learn from the study. Forexample, the statement, "The study will tell us A and B, and anaccuracy of C. Nature and scope of operations management? Operations management is often used along with production management in literature on the subject. It is therefore, useful to understand the nature of operations management.

Operations management is understood as the process whereby resources or inputs are converted into more useful products. A second reading of the sentence reveals that, there is hardly any difference between the terms produ7ction management and operations management. But, there are a least two points of distinction between production management and operations management. First, the term production management is more used for a system where tangible goods are produced.

Whereas ,operations management is more frequently used where various inputs are transformed into tangible services.

Viewed from this perspective, operations management will cover such services organization as banks ,airlines ,utilities ,pollution control agencies super bazaars, educational institutions ,libraries ,consultancy firm and police departments, in addition ,of course ,to manufacturing enterprises. The second distinction relates to the evolution of the subject. Operation management is the term that is used now a days. Production management precedes operations management in the historical growth of the subject The two distinctions not withstanding, the terms production management and operations management are used interchargeably.

Scope of Production and Operation Management The scope of production and operations management is indeed vast. Commencing with the selection of location production management covers such activities as acquisition of land, constructing building ,procuring and installing machinery ,purchasing and storing raw material and converting them into saleable products. Added to the above are other related topics such as quality management ,maintenance management ,production planning and control, methods improvement and work simplification and other related areas.

What is the nature and scope of business research? Business research has four basic characteristics. It has a timelimit. It is applied research. It is almost always conducted in arapidly-changing environment, and it is a for-profit enterprise. Explain the scope and methodology of operational research with an example? Operational research uses statistical analysis, mathematicalmodeling, and mathematical optimization to reach optimal solutionsfor complex decision making processes.

An example would be planningthe floor layout of a factory to reduce manufacturing time. Scope Limitation about a feasibility study? There have been feasibility studies done on the coopt of limitationfor machine translations. These machines would make readingmaterials for chemical education.

What is the scope for doing research in electronics? To invite more efficient device, reduction in cost for products, easy maintanence and weights less device What is the scope of Advertising Research? The scope of advertising research depends with various factors liketime, funds and the available resources. At the end of the day thegiven advertisement should research the intended audience.

What considerations limit the scope of a laryngectomy? Partial laryngectomies are done when cancer is limited to one spot. What are the scope and limitations of disaster management? Measuring the success during a natural disaster can be difficultdue to the number of variables at any given time.

Disastermanagement deals with all the situations leading up to, during, andafter the disaster and its scope is to reduce losses of the societyat large as well as to reduce personal suffering and speedrecovery.

Disaster management teams are largely limited by theirfunding. What are the scope and limitation of online reservation? What is the scope of social research in India?

The origin of the survey can be traced back at least early as the Domesday Book in , [7] [8] whilst some scholars pinpoint the origin of demography to with the publication of John Graunt's Natural and Political Observations upon the Bills of Mortality.

While Durkheim rejected much of the detail of Comte's philosophy, he retained and refined its method, maintaining that the social sciences are a logical continuation of the natural ones into the realm of human activity, and insisting that they may retain the same objectivity, rationalism, and approach to causality.

What has been called our positivism is but a consequence of this rationalism. By carefully examining suicide statistics in different police districts, he attempted to demonstrate that Catholic communities have a lower suicide rate than that of Protestants, something he attributed to social as opposed to individual or psychological causes.

He developed the notion of objective suis generis "social facts" to delineate a unique empirical object for the science of sociology to study. For Durkheim, sociology could be described as the "science of institutions, their genesis and their functioning. What are the scope and limitations of the RH bill? The Reproductive Health Bill promotes information and access toboth natural and modern family planning methods, which aremedically safe and legally permissible.

RH bills may help and italso may trigger someone to do such things to ruin their life. What are the limitations of operation research? Dependence on an Electronic Computer: In the modern society, these factors are enormous and expressing them in quantity and establishing relationships among these require voluminous calculations that can only be handled by computers.

All relevant variables do not lend themselves to quantification. Factors that cannot be quantified find no place in O. Distance between Manager and Operations Researcher: Similarly, a manager fails to understand the complex working of O. Thus, there is a gap between the two. Money and Time Costs: When the basic data are subjected to frequent changes, incorporating them into the O. Moreover, a fairly good solution at present may be more desirable than a perfect O.

Implementation of decisions is a delicate task. It must take into account the complexities of human relations and behaviour. What are the scope and limitation of rh bill? One of thedisadvantages of this type or researchbnb is that you never get todelve too deeply into a specific point. What are the disadvantages of carrying out market research? Disadvantage of using market research is that it will cost a lot as it will be expensive to carry out, purchasing paper so it could be used to print the questionnaire on then this could cost.

The market research could be invalid as it may be out of date and not relevant. What are the advantages and disadvantages of internal research? Working with research firms requires somewhat rigid guidelines and research requirements. Companies using an internal marketing research department obtain built-in agility to modify research during the course of the investigation.

Internal marketing teams can also move at the pace set by business needs.. Expenses Hiring external firms for marketing research may be more expensive than using corporate employees. Costs, expenses and resources can be tightly monitored and controlled when an in-house staff conducts investigations.. Customization Internal employees tap product, development and support staff for in-depth product knowledge, questions and advice. This resource advantage allows internal marketing teams to customize and maximize research efforts.

For example, marketing staff could discuss product feature options with engineering staff to help craft a survey to establish customer product preferences for future models.. What are the disadvantages of using the internet for research?

If you are doing research on the web Just remember not Everything is true People could say purple aliens are on Mars! Nobody could stop them! What are the advantages and disadvantages of correlational research?

Correlational research is beneficial because it helps researchers to see the relationship between two or more things. It helps narrow down possible causes for diseases, behaviors, etc. For example, discovering the correlation between smoking and cancer has led to much research and literature informing individuals who smoke of their increased chance of developing cancer. However, correlational studies can be disadvantageous as well.

It is important to know the distinction between "correlation" and "causation. Just because two factors are correlated does not mean that one caused the other. For example, we may see that there is a positive correlation between drowning and ice cream sales that is, the number of drownings increases as the number of ice cream sales increase.

Does this mean that ice cream causes drowning? No; perhaps it is just because it is summertime and people are more likely to buy ice cream, just as they are more likely to go swimming. It is important to take these other factors into account. What is the role and significance of operations research? The role of Operations Research role is dealing with advancedmethods for making better decisions significant to math, science,and industrial engineering.

Advantages and disadvantages of archival research? What are the disadvantages of action research? What are the phases of Operations research? 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 are the advantages and disadvantages of scientific research? Allows the study of the world around us, and to be able to understand everything and how things are connected. Helps us to discover new things.

Sometimes it takes alot of time for a breakthrough, and this is also a big cost factor. Sometimes scientists 'fake evidence' to get government funding. What are the limitations of operation research? Dependence on an Electronic Computer: Distance between Manager and Operations Researcher: Money and Time Costs: What is a dummy variable in Operations research? There are various forms. In linear programming, a dummy variable may be used to convert aninequality into an equation.

For example x 0. In this case, it is also called aslack variable. Dummy variables are used in regression to indicate the presence orabsence of a factor, or for binary variables. What are the disadvantages of research report?

There are voluminous of applications of Operations Research. Although it is not feasible to cover all applications of O. The following are the abbreviated set of typical operations research applications to show how widely these techniques are used today: Assigning audit teams effectively Credit policy analysis Cash flow planning Developing standard costs Establishing costs for byproducts Planning of delinquent account strategy Construction: Project scheduling, monitoring and control Determination of proper work force Deployment of work force Allocation of resources to projects Facilities Planning: Building cash management models Allocating capital among various alternatives Building financial planning models Investment analysis Portfolio analysis Dividend policy making Manufacturing: Inventory control Marketing balance projection Production scheduling Production smoothing Marketing: Personnel planning Recruitment of employees Skill balancing Training program scheduling Designing organizational structure more effectively Purchasing: Optimal buying Optimal reordering Materials transfer Research and Development: Operations Research has number of applications; similarly it also has certain limitations.

These limitations are mostly related to the model building and money and time factors problems involved in its application.
