Organisational management can benefit from the analytical problem-solving and decision-making process known as operations research (OR). In operations research, issues are deconstructed into their simplest forms before being mathematically analysed and then resolved in a set of processes. 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 identify the most effective problem-solving methods. Operations research is a broad field that includes many different approaches to tackling issues that are used to increase effectiveness and decision-making. In order to find optimal or nearly optimal solutions to challenging decision-making situations, this book applies advanced analytical techniques from formal science and applied mathematics, including mathematical modelling, statistical analysis, and mathematical optimisation. It frequently focuses on figuring out the maximum or lowest of some real-world objective.
