What is operations research?

Operations research is a discipline that uses mathematical modeling, statistical analysis, and optimization techniques to help organizations make better decisions and solve complex problems. It involves applying scientific methods to improve decision-making processes in areas such as logistics, supply chain management, finance, marketing, and healthcare. Operations research aims to maximize efficiency, minimize costs, and optimize resource allocation in order to achieve the best possible outcomes.

Operations Research (OR)

Operations Research is an interdisciplinary field that uses scientific methods to analyze and improve complex systems, particularly those involving decision-making under uncertainty. It involves the application of mathematics, statistics, and computer science to optimize operations and maximize effectiveness.

Key Features of Operations Research:

- Systems Approach: Focuses on analyzing complex systems as a whole, considering their interdependencies and interactions.
- Quantitative Modeling: Employs mathematical and statistical models to represent real-world systems and quantify decision variables.
- Optimization: Seeks to find the best possible solutions (optimums) to decision problems, considering multiple objectives and constraints.
- Uncertainty and Risk Management: Deals with situations where outcomes are uncertain and seeks to minimize risks and maximize expected outcomes.

Applications of Operations Research:

Operations research is widely applied in various industries and domains, including:

- Manufacturing: Production scheduling, inventory management
- Supply Chain Management: Logistics, forecasting, optimization
- Healthcare: Resource allocation, patient flow, treatment planning
