Linear Programming is a mathematical technique to find the optimal value for a linear system of objective function and constraints.
Modeling is an art, not a precise science. All mathematical models necessarily contain some degree of simplification of the real world that we are attempting to describe.
Different modelers will make different assumptions, and come up with different models of more or less precision, and certainly of different sizes, having different numbers of decision variables.
Linear Programming (LP)
Linear programming (LP) is the best known mathematical optimization technique to allocate scarce resources to competing activities in an optimal manner when the problem can be expressed with continuous decision variables, linear in both objective function and inequality constraints.
