The study of using mathematics to answer business concerns is known as operations research, often known as decision science or operations analysis. It is one of the major subjects taught in BBA, provided you are enrolled with the **Top Placement Colleges For BBA In Delhi NCR**. It occupies a highly intriguing place alongside other disciplines like Data Science and Machine Learning as a branch of Applied Mathematics.

**Which questions are answered by operations research?**

Let’s look at a few sample applications of operations research before diving into the actual definition of the field. You’ll see that they all share a few characteristics; we’ll talk about that shortly.

**Operations research examples:**

**1. Linear Programming**

You presumably encountered linear equations in math classes in school, and you could have learnt how to answer them using a pen and paper. An optimization method known as linear programming uses a linear objective function to handle systems with linear constraints. It is the Operations Research technique that is most known.

**2. Waiting line theory or queuing theory.**

Queuing Theory is the second area in operations research. The previous example may have been clearer, but a waiting line can also be precisely defined mathematically. Once this is completed, queueing theory enables a corporation to comprehend and enhance client wait times while also improving worker management.

Although it differs significantly from the other uses covered in this blog, job scheduling by computer operating systems is nonetheless an essential application of queueing theory.

**3. Inventory control systems**

Inventory Control is the second problem that operations research addresses. For a business, inventory control is a complex process that depends on numerous choices, including those related to purchasing, warehousing, shipping, tracking, and other issues. Several solutions that address all of an organization’s inventory tasks are grouped together by inventory control systems. Economic Order Quantity (EOQ), Inventory Production Quantity (IPQ), and ABC Analysis are the three most popular techniques for inventory management. You ought to look into those if you want to learn more about inventory management.

**4. Replacement problems**

Optimizing the replacement of materials that are known to fail after a specific amount of usage is the focus of replacement challenges, which are somewhat similar to the previous ones. When replacing expensive goods like machinery, automobiles, computers, etc. either too early or too late, a corporation incurs significant costs. As a result, this is a good query for operations research optimization.

**5. Network Analysis**

The subject of network analysis is somewhat distinct from the things that were listed earlier. An application is modelled as an optimizable graph in network analysis. Graphs made up of nodes and edges occur in graph theory generally. Every node is a point, and every edge shows whether a particular set of nodes are connected to one another. A social media network, where each user’s profile is represented as a node and each friendship relationship as an edge, is an excellent example of this type of data.

**6. Sequencing Problems**

The sequence in which numerous actions should be carried out while using a finite amount of resources is the subject of this discussion. We have a variety of options for execution in this case, and we want to make sure we select the optimal one. You can optimise the overall duration of operations, the cost, or the benefit depending on the cost function you choose. First Come First Served (FCFS), Shortest Processing Time (SPC), Earliest Due Date (EDD), and more sequencing techniques are available.

**The Three Essential Elements Of Any Topic In Operations Research:**

**1. Algorithms and Statistics**

Algorithms, mathematics, and statistics will play a significant role in operations research. The family of algorithms known as optimization algorithms, which attempt to discover a maximum or a minimum given a particular set of options, is a crucial one in operations research.

This can be demonstrated by using an optimization algorithm to reduce the cost of staffing a factory, given a set of limitations on the required workforce and limits placed on each employee.

**2. Optimization**

The process of determining the best answer to a problem given any probable practical limitations. The goal of optimization can be to maximise or minimise a cost or benefit that has been predetermined.

As we apply weights to our various expenses, we can build a combined cost function if we have numerous goals (for example taking the sum of two costs to minimise could be an example of a combined cost function).

Constraints are a second frequent issue that must be handled in such optimizations. A cost reduction algorithm may occasionally search for answers in a way that is physically impractical. While determining the ideal staffing strategy, for instance, we want to restrict the algorithm from scheduling individuals for 24-hour shifts because that is plainly against the law.

**3. Simulation**

**Actually, the task of optimization is similar to that of simulation.**

We could ask an algorithm what the impact of changing the planning would be rather than asking it what the ideal staffing strategy is. This kind of assignment is similar to optimization because we can easily simulate what the optimal result would be given various input configurations by using the optimization technique.

Hence, operations research can be defined as the application of mathematics to business problems with the intention of optimization and/or simulation.
