Management Science refers to solving managerial problems related to quantitative factors. Steps carried out by management scientists include: defining the problem and gathering data, formulating a model (typically a mathematical model) to represent the problem, deriving solutions to the problem from the model. Based on this procedure, the module will focus on introducing and analyzing different optimization techniques and models. Throughout the module, students will be guided the use of spreadsheets to run math operations. However, this module does not deeply go into the algorithm aspects of these models. Instead, it aims to analyze why and how these models are applied in solving managerial problems. The analysis of the requirements of data input and the interpretation of results will also be emphasized.
