Applications of Operations Research in Various Fields with Examples

Applications and Scope of Operations Research in Various Fields with Examples – In its recent years of organized development, O.R. has solved successfully many cases of research for the military, the government and industry. The basic problem in most of the developing countries in Asia and Africa is to remove poverty and hunger as quickly as possible. So there is a great scope for economists, statisticians, administrators, politicians and technicians working in a team to solve this problem by an O.R. approach.

Its main objective is to optimize the use of resources and obtain the best possible results. So, today, Operations Research is widely used in business, industry, transportation, healthcare, defense, and many other areas. Because of its vast usefulness, the scope of Operations Research is continuously expanding.

Besides this, OR is useful in the following various important fields:

Applications of Operations Research in Various Fields with Examples

1. In Agriculture:

Modern agriculture also benefits from Operations Research. With the explosion of population and consequent shortage of food, every country is facing the problem of-

optimum allocation of land to various crops in accordance with the climate conditions; and
optimum distribution of water from various resources like canal for irrigation purposes.

Thus there is a need of determining the best policies under the prescribed restrictions. Hence a good amount of work can be done in this direction.

Applications

Crop planning
Irrigation scheduling
Fertilizer allocation
Farm management

Example

Farmers can determine the most profitable combination of crops using Linear Programming.

2. In Finance / In Financial Management:

Operations Research helps in efficient utilization of financial resources. In these modern times of economic crisis, it has become very necessary for every government to have a careful planning for the economic development of her country. OR techniques can be fruitfully applied:

to maximize the per capita income with minimum resources;
to find out the profit plan for the company;
to determine the best replacement policies, etc.

Applications

Capital budgeting
Investment analysis
Portfolio management
Risk analysis

Example

Banks and investment firms use mathematical models to minimize risks and maximize returns.

3. In Industry:

If the industry manager decides his policies (not necessarily optimum) only on the basis of his past experience (without using OR techniques) and a day comes when he gets retirement, then a heavy loss is encountered before the Industry. This heavy loss can immediately be compensated by newly appointing a young specialist in OR techniques in business management.

Thus OR is useful to the Industry Director in deciding the optimum allocation of various limited resources such as men, machines, materials, money, time, etc., to arrive at the optimum decision.

4. In Allocation and Distribution:

Optimal allocation of limited resources such as men, machines, and materials.

Location and size of warehouses, distribution center, retail depot etc.
Distribution policy.

5. In Marketing Management:

Operations Research assists managers in making better marketing decisions. With the help of OR techniques a Marketing Administrator (Manager) can decide:

where to distribute the products for sale so that the total cost of transportation etc. is minimum;
the minimum per unit sale price;
the size of the stock to meet the future demand,
how to select the best advertising media with respect to time, cost, etc.
how, when, and what to purchase at the minimum possible cost?

Applications

Market research
Advertising budget allocation
Product selection
Sales forecasting

Example

Companies analyze consumer demand to decide which products should be promoted.

6. In Personnel Management:

A personnel manager can use OR techniques:

to appoint the most suitable persons on minimum salary,
to determine the best age of retirement for the employees,
to find out the number of persons to be appointed on a full-time basis when the workload is seasonal (not continuous).

7. In Production Management:

Operations Research helps industries increase production efficiency and reduce production costs. A production manager can use OR techniques:

to find out the number and size of the items to be produced;
in scheduling and sequencing the production run by proper allocation of machines;
in calculating the optimum product mix; and
to select, locate, and design the sites for the production plants.

Applications

Production planning
Job scheduling
Machine allocation
Quality control
Capacity planning

Example

A manufacturing company can use Linear Programming to maximize profit while using limited resources efficiently.

8. In Procurement:

What, when and how to purchase at minimum procurement cost
Bidding and replacement policies

9. In Banking and Insurance / L.I.C.:

Operations Research improves the efficiency of financial institutions.

OR approach is also applicable to enable the LIC offices to decide:

what should be the premium rates for various modes of policies,
how best the profits could be distributed in the cases of with profit policies? etc.

Applications

Risk management
Loan analysis
Investment decisions
Queue management

Example

Banks optimize customer service operations to reduce waiting time.

10. In Education, Research and Development:

Educational institutions also use Operations Research techniques.

Applications

Determination of the areas of concentration of Research and Development
Reliability & control of the development of projects
Selection of projects & preparation of their budgets.
Timetable preparation
Resource planning
Admission management
Research optimization

20. Purchasing:

Applications

Optimal buying
Optimal reordering
Materials transfer

Also, OR techniques can be used in Defense Operations, Traffic control, In hospitals, etc. Finally, we can say: wherever there is problem, there is OR.

Scope of Operations Research

The scope of Operations Research is very wide. It is used wherever decision-making, planning, scheduling, optimization, and resource allocation are involved.

Operations Research is applied in:

Production and manufacturing
Inventory control
Marketing management
Financial management
Human resource management
Transportation and logistics
Healthcare services
Military operations
Agriculture
Project management
Banking and insurance
Education and research
Telecommunication systems
