In today's complex and interconnected world, the rigorous techniques and methodologies of operations research have become especially important aids to informed decision making. Operations research is the discipline of applying advanced analytical methods to help make better decisions. It uses mathematical modeling, analysis, and optimisation in a holistic approach to improving students' knowledge of systems and designing useful, efficient systems. Its applications range from engineering to management and from industry to the public sector. The course emphasises the use of mathematics optimisation, applied probability and statistics for pricing goods and services, marketing them, improving transportation, as well as for many other business areas. It embodies many models which enhance the skills of quantitative methods, decision analysis, forecasting, inventory control, linear programming, networking and transportation.
