Meaning of linear programming 2 limitations of linear programming meaning of linear programming: lp is a mathematical technique for the analysis of optimum decisions subject to certain constraints in the form of linear inequalities. Linear inequalities to begin our work in linear programming, we fi rst have to develop some skills with linear inequalities recall that linear equations come in two forms: y = mx + c and ax + by = c for example, y = 3x – 4 is a linear equation, as is 3 +x 4y = –9 linear inequalities also have two forms: y mx + c and ax + by c for example, y 3x – 4 is a linear inequality, as is.
Linear programming is the process of taking various linear inequalities relating to some situation, and finding the best value obtainable under those conditions a typical example would be taking the limitations of materials and labor, and then determining the best production levels for maximal profits under those conditions.
