The document provides an overview of quantitative analysis and the quantitative analysis approach. It discusses key concepts like the steps in the quantitative analysis approach, which include defining the problem, developing a model, acquiring input data, developing a solution, testing the solution, analyzing results, and implementing results. It also discusses mathematical models, decision variables, parameters, algorithms, and sensitivity analysis. Potential problems in quantitative analysis are outlined, such as conflicting viewpoints, poor assumptions, and inaccurate data.
