Linear programming.

A linear programming model can be expressed canonically as: Maximise: \ ( c^ {T} x \) subject to: \ ( Ax \le b \) and: \ ( x \ge 0 \) where x represents the vector of decision variables, c and b are vectors of known coefficients and A is a known matrix of coefficients. Objective function c·x can be maximised or minimised.The linear programming formula may be regarded as follows: The function of the formula: ax + by = Z. The formula’s operating limitations: cx + dy ≤ e and fx + gy ≤ h. Other, non-negative restrictions: x ≥ 0, y ≥ 0. You need to know a few terms to understand the meaning of linear programming. First come the decision variables.Jan 1, 2016 · Introduction. Linear programming is one of the most widely used techniques of operations research and management science. Its name means that planning (programming) is being done with a mathematical model (called a linear-programming model) where all the functions in the model are linear functions. A linear program is in canonical form if it is of the form: Max. z = cT x subject to: Ax b. ≤. x 0. ≥. A linear program in canonical form can be replaced by a linear program in standard form by just replacing Ax b by Ax + Is = b, s 0 where s is a vector of slack variables and I is the m m. ≤ ≥ ×. identity matrix.

The starting point is still a matrix equation Ax = b. But the only acceptable solutions are nonnegative. We require x ≥0 (meaning that no component of x can be negative). The matrix has n > m, more unknowns than equations.
