This document provides an introduction to linear programming problems (LPP). It defines key terms like linear, programming, objective function, constraints, and decision variables. It explains that an LPP aims to optimize a linear objective function subject to linear constraints. The document outlines the steps to formulate an LPP model, including defining the objective, decision variables, objective function, constraints, and non-negativity condition. It provides an example of formulating an LPP model and lists areas where LPP can be used for business decision making.
