Decision science is a mathematical discipline that considers how to make appropriate and better decisions in complex decision-making problems. It deals with how best to design, operate and/or predict behavior of complex systems like people, machinery, materials and money in industry, business, finance, education, government and defence. Mathematics graduates play integral roles in the workplace, developing mathematical models and numerical algorithms to answer what-if scenarios, and design experiments to help guide research and improve processes. Why choose this course? The decision science major encompasses the study of quantitative techniques relevant to decision-making in its broadest sense. You will employ a problem-solving approach, using advanced analytical methods such as operations research, financial mathematics, stochastic and mathematical modelling, and mathematical optimisation. You will also use a variety of software and improve your information technology skills. Because of its emphasis on human-technology interaction and its focus on practical applications, decision science overlaps with other disciplines, notably industrial engineering and operations management, economics and finance, so it is a multidisciplinary field. The coursework also introduces you to different industries and processes that greatly contribute to the economy and environment of nations around the world. These include manufacturing and production, management, health care, finance and economics, goods and services, infrastructure, transportation and logistics, mining and defence. This study area provides a foundation for a variety of careers and further study. Customise your degree Foster your passion and shape your career through complementary study areas. As well as choosing a major area of study, your course includes a second study area, which can be either a second major or double minor. A second major can complement your major area of study, giving you the opportunity to develop a significant depth of knowledge and skills in two discipline areas. Mathematics Second Major ​Data Science provides the necessary skills to be a data scientist including statistical methods and data visualisation, computational tools for and data management techniques for large datasets, and high-performance computing resources and techniques. This unique skill-set in statistics and computing will allow you to cope with sophisticated models applied to complex and/or large datasets. Career outcomes Decision science graduates typically have a wide range of choices for employment. The job markets for actuaries, finance and operations research analysts have been quite strong in recent years and are expected to remain so in the near future. In addition, students with excellent grades who desire more education in these areas will find a large number of opportunities for postgraduate study. The decision science major prepares you for careers or for further postgraduate study in such technical fields as operations research, management science, information technology, industrial engineering, strategic planning, systems analysis, financial analysis and actuarial science.
