Operations Research (OR) is a field in which people use mathematical and engineering methods to study optimization problems in Business and Management, Economics, Computer Science, Civil Engineering, Electrical Engineering, etc. In this course, we focus on the “modeling and applications” and “algorithms” parts. The major objective is to let students know the fundamental way of using OR to support decision making in all kinds of business applications, including production, inventory, pricing, locations, among others. Students will learn how to formulate mathematical programs and use computers to solve these business problems. Moreover, students will also learn the underlying algorithms that solves linear programs, integer programs, and nonlinear programs. This will benefit their future studies in related fields.
