Linear Programming Problems – Formulation Linear Programming is a mathematical technique for optimum allocation of limited or scarce resources, such as labour, material, machine, money, energy and so on , to several competing activities such as products, services, jobs and so on, on the basis of...
The steps involved in mathematical modelling or formulation of different types of linear programming problems are given below:Step 1: Identify the decision variables: The first step is to identify the decision variables that govern how the objective function behaves. An objective function is one that...

This modified algorithm appears to be significantly more efficient in practise than a more straightforward interior point approach via a linear programming formulation: we present numerical results to support this claim.

In the recent years we have seen many approaches to solve fractional programming problems. In this paper, the linear fractional programming problem with interval coefficients in objective function is solved by the variable transformation. In this method a convex combination of the first and the last...
