Operations research is an analytical method for problem-solving and effecient decision-making that is useful to achieve organization goal.

Operations research refer the process of broken down the problem into basic structure and then it will be solved in defined steps and procedure by mathematical analysis.

In any aspect of life, difficult decisions abound.

Operation research, like a scientific research which based on scientific process which involves various steps and procedure.

When faced with such a choice, we frequently choose to consider our options logically and sensibly in order to determine which could be the greatest option in light of our objectives.

Even if we may not have many options, we can always consider each one thoroughly and what it has to offer before deciding which is ideal for us.

## Operational Research

Operational Research is the application of comparable concepts to more significant, complex choices involving the operations of systems, including organisations and networks of machines.

In order to solve a numerical version of the problem at hand, using mathematical techniques is required while making these decisions using OR.

## Features of Operations Research

There are three primary Features of operations research are:

**Optimization**– The goal of operations research is to produce the greatest performance possible given the available conditions. Additionally, optimization entails contrasting and limiting available possibilities.

**Simulation**– Building replicas or models is one way to test your ideas before putting them into practise.

**Probability and statistics**– This includes utilising data and mathematical algorithms to identify important insights and dangers, generate accurate forecasts, and test potential solutions.

The first thing that needs to be understood in OR is the aim or goal because it explains what we want from a solution and enables us to compare various ones.

The goal is typically measurable in termof cost or profit.

## Importance of Operations Research

When it comes to decision-making, Operations Research offers a more potent method than standard software and data analytics technologies. Employing operations research experts can assist businesses in obtaining more comprehensive datasets, taking into account all available options, forecasting all potential outcomes, and estimating risk. Additionally, operations research can be customised to certain company procedures or use cases to ascertain the most effective strategies for problem-solving.

- Operation Research entails carrying out this same action by examining the system’s architecture and individual parts in order to gather as much numerical data as feasible.

- Numerous aspects of a system, such as the resources at its disposal, its energy effectiveness, the number of its workforce, and so forth, can be quantified.
- By doing this, these properties are made simple to compare and we can see how they effect our goal.

- Operation Research also entails developing a thorough grasp of the system, how it functions, and the connections between its parts.

- This is crucial in order to understand how restricting the problem can lower the amount of possibilities we have to think about and how constraints on one component might lead to restrictions on other parts.

- For instance, increasing the number of people in a company increases costs, while increasing the system’s machine power decreases energy efficiency.

- We may identify the system’s limitations and the elements that are most important to us by developing a thorough grasp of the system.

The goal of Operation Research practitioners is to be able to represent the problem mathematically as accurately as possible by collecting numerical representations and researching the dynamics of the system.

## Objective of Operation Research

Due to the objectivity of numbers and the fact that they can almost always be optimised, mathematical problems can often be resolved significantly more quickly.

To assist in doing this, numerous strategies have been developed over time. All of them are understood and effective. However, these approaches don’t always yield the optimal solution for issues that are quite complex.

Because of this, Operation Research also calls for the use of heuristics, which are additional techniques meant to get as close as feasible to the best option.

- Operation Research takes place following the problem-solving phase in a significant way.

- The practitioner will have a mathematical solution because they will have solved a mathematical problem.

Therefore, converting this response into a solution that is in terms of the initial, real-world problem is a crucial component of Operation Research.

- People who work in Operation Research are frequently involved in putting the decision they have recommended into practise because they have such a thorough understanding of the system thanks to the modelling stages.

Depending on whether or not it performs as planned, they can then offer advice.

Operation Research is the process of transforming a real-world operational problem into a mathematical one, solving it, then explaining and putting the solution into practise.

## Applications of operations research

- Scheduling and time management.
- Urban and agricultural planning.
- Enterprise resource planning (ERP)
- supply chain management (SCM).
- Inventory management.
- Network optimization and engineering.
- Packet routing optimization.
- Risk management.

## Process of Operation Research

The six process involves in operation research are as follows:

- Identification the Problem
- Constructing a Model arround the specific problem
- Finding Solution from the Model
- Testing the Solution
- Establishing relationship and Controls over the Solution
- Implementation of the Solution.

### Identification the Problem

Operation research examines how a person, machine, or organisation functions and must take operation economics into account.

To identify a problem for Operation Research study analysis, the following key elements must be present:

(i) **Environment**

(ii) **Objectives**

(iii) **Decision maker**

(iv) **Alternative courses of action and constraints.**

Environment is the most comprehensive of the aforementioned four elements since it sets the stage for the other three.

The operation researcher must go to conferences, do site visits, send out observers, and conduct research in order to gather enough information to formulate problems.

### Constructing a Model arround the specific problem

Constructing a model arround the specific problem and investigation is the next stage once the project has received management approval.

In order to demonstrate the relationships and interactions between a cause and effect or between an action and a reaction, the operation researcher can now build the model.

Currently, an operation researcher’s goal is to create a model that will allow him to predict the impact of variables that are important to the resolution of a given problem.

In order for the suggested model to function under the specified environmental limitations, it may be tested and updated.

If management is dissatisfied with a model’s performance, it may also be changed.

### Finding Solution from the Model

One way to extract a solution from a model is to simulate trials on it or use mathematical analysis.

If the data are inappropriate, no model will function properly. Such knowledge could be gleaned via experiment findings or from educated guesses. It is obvious that the date collection has a substantial impact on the model’s output.

The goal of the operation researcher should not be taken for granted once his objective and model have been established.

If data gathering errors are to be kept to a minimum, it takes time to prepare the necessary data collection.

### Testing the Solution

The usefulness or utility of a solution is checked by finding out how well it predicts the effective key changes. Such an analyse is commonly known as sensitivity antamanagement 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.

e next phase for the operation researcher is to

### Establishing relationship and Controls over the Solution

The goal of Operation Research practitioners is to be able to represent the problem mathematically as accurately as possible by collecting numerical representations and researching the dynamics of the system.

Employing operations research experts can assist businesses in obtaining more comprehensive datasets, taking into account all available options, forecasting all potential outcomes, and estimating risk. Additionally, operations research can be customised to certain company procedures or use cases to ascertain the most effective strategies for problem-solving.

### Implementation of the Solution

The last phase of the operation research process is to implement the solutions obtained in Establishing rimplementation involves so many. Operations research is an analytical method for problem-solving and effecient decision-making that is useful to achieve organization goal.
