Operations research, often abbreviated as OR, is a discipline that uses mathematical and analytical methods to solve complex decision-making problems in various fields, including business, engineering, healthcare, logistics, and the military. Its primary goal is to optimize decision-making processes and improve efficiency.

Why is operations research important?

To answer 'Why is operations research important?', operations research supports organizations in making big decisions, particularly when the correct answer to a problem may not be apparent. Operations research is a way of gaining clear answers based on different factors. For example, if an organization is unsure where to buy premises, using operations research and considering factors such as travel, area cost, and supply chains can provide an answer to which of several sites may allow for maximum profit. Some reasons that operations research is important include:

1. Enhanced decision-making

Operations research helps business owners and managers make crucial decisions, using individual factors to find the ideal outcome. By taking multiple different factors and reducing them to fit the formula, businesses get an idea of what may be the best option without the confusion of large amounts of data. Operations research helps find the optimal solution to a specific problem, allowing organizations to make informed decisions out of the options available to them.

2. Higher level of control

The techniques and processes used for operations research provide decision-makers with the tools and information necessary to have better control over their decisions. This clarity also provides direction to staff within the organisation, allowing for the quick identification of areas requiring improvement. For example, operations research provides a foundation for testing performance standards, allowing managers to see what resources are suitable for optimization.

3. Improved productivity

The primary purpose of operations research is to help organizations identify the optimal approach to solving a problem. This optimization allows organizations to improve their productivity and efficiency by providing information on the ideal option for inventory mix, workforce, or machinery usage. As operations research quantifies a diverse range of factors, this information supports the introduction of better productivity measures focused on achieving the optimal result calculated with OR.

4. Effective coordination

Coordination across different departments directly impacts productivity and flexibility within an organization. Operations research directly supports better coordination across different departments based on what's optimal for the organization as a whole. For instance, marketing and sales departments within an organization align with the schedules designed to maximize production, ensuring every team has the information and knowledge necessary to make effective decisions.

5. Quantified issues

Operations research provides a way of quantifying issues that are difficult to explain. For example, deciding which product to sell based on space, time and labour may include many individual factors. By quantifying and simplifying these factors into a single formula, it's easier to make decisions based on the most suitable outcome. Quantifying solutions also helps bring potential results to a management team or stakeholders for approval.

6. Better clarity

Clarity is critical in making business decisions. Operations research improves management's clarity around specific topics and problems, reducing the confusion and chances of misunderstanding for easier decision-making. This formula breaks issues down into a simple form, allowing owners and managers to have clarity over arising situations and future problems as quickly and effectively as possible. Having a clear idea of the outcomes makes it easier for managers to make important, potentially costly decisions.

Operations research is an interdisciplinary field that draws on mathematics, statistics, computer science, and engineering. It is employed in a wide range of industries and applications to improve decision-making, reduce costs, increase efficiency, and enhance overall performance. Operations researchers work closely with domain experts to model and solve complex problems, making it a valuable tool for addressing real-world challenges.
