Iterative computations of the Transportation algorithm
Iterative computations of the Transportation algorithm After determining the starting BFS by any one of the three methods discussed earlier, we use the following algorithm to determine the optimum sol
Determination of Starting Basic Feasible Solution
Determination of the starting Solution In any transportation model we determine a starting BFS and then iteratively move towards the optimal solution which has the least shipping cost. There are three
The Transportation Model Formulations
The Transportation Model The transportation model is a special class of LPPs that deals with transporting(=shipping) a commodity from sources (e.g. factories) to destinations (e.g. warehouses). The objective is to det
The Simplex algorithm
Abstract: In this lecture we discuss the computational aspects of the Simplex algorithm. We shall see how a LPP is put into a simplex tableau. Starting from a BFS, we explain how to proceed step by step till we reach the optimal solu
Algebraic Solution of LPPs - Simplex Method To solve an LPP algebraically, we first put it in the standard form. This means all decision variables are nonnegative and all constraints (other than the nonnegativity restrictions) are equations with nonnegati

Sensitivity Analysis The optimal solution of a LPP is based on the conditions that prevailed at the time the LP model was formulated and solved. In the real world, the decision environment rarely remains static and it is essential to determine how the opt

INTEGER LINEAR PROGRAMMING
There are many LP problems in which the decision variables will take only integer values. If all the decision variables will only take integer values it is called a pure integer LPP; otherwise the problem is called a mixed integ
Dual Problem of an LPP Given a LPP (called the primal problem), we shall associate another LPP called the dual problem of the original (primal) problem. We shall see that the Optimal values of the primal and dual are the same provided both have finite fea
Integer Programming Problems Many of the LPP requires that the solution be integers. For example, if the problem is to estimate the maximum profit for a manufacture that produces radios, TVs, and DVDs. The problem requires you to find how many of each pro
