Operations Research (OR), also known as management science or decision science, is a multidisciplinary field that uses mathematical modeling, statistical analysis, and optimization techniques to solve complex decision-making problems in various organizations and industries. It focuses on the application of quantitative methods and analytical approaches to improve decision-making processes and the allocation of resources.

Problem Solving
Operations Research aims to address complex problems and make better decisions. These problems often involve allocating limited resources, optimizing processes, and maximizing efficiency or minimizing costs.
Mathematical Modeling
OR professionals use mathematical models to represent real-world systems and decision scenarios. These models can take the form of linear or nonlinear equations, networks, simulation models, and more.
Optimization
Optimization is a central theme in OR. It involves finding the best possible solution to a problem within given constraints. This can include optimizing supply chain logistics, production schedules, workforce allocation, and more.
Decision Support
OR tools and techniques help decision-makers by providing them with data-driven insights and recommendations. These tools enable managers to make informed choices and evaluate the potential outcomes of different decisions.
Interdisciplinary Approach
Operations Research draws upon a wide range of disciplines, including mathematics, statistics, computer science, economics, engineering, and management. It applies these various fields to tackle complex, real-world problems.
Applications
OR is used in a diverse array of applications, including transportation and logistics, manufacturing, healthcare management, finance, energy optimization, military operations, and public policy. For example, it can be used to optimize airline flight schedules, design efficient healthcare delivery systems, or improve investment portfolio management.
Techniques
Common techniques used in OR include linear and nonlinear programming, integer programming, network analysis, queuing theory, simulation, and Monte Carlo methods, among others.
History
OR emerged during World War II when mathematicians and scientists were tasked with solving military logistics and planning problems. Since then, it has evolved and expanded into various industries and sectors.
Software Tools
OR practitioners often use specialized software tools and programming languages (e.g., MATLAB, R, Python, and commercial packages like IBM CPLEX) to build and solve mathematical models efficiently.
Ethical Considerations
OR practitioners must consider ethical issues related to their work, such as the potential impact on society and the environment, as well as ensuring that decisions are made fairly and equitably.
Operations Research is a valuable field that continues to evolve with advancements in technology and data analytics. It plays a crucial role in helping organizations make better decisions, improve efficiency, and achieve their goals more effectively.
