SENSITIVITY ANALYSIS IN LINEAR PROGRAMING: SOME CASES AND LECTURE NOTES Samih Antoine Azar, Haigazian University CASE DESCRIPTION This paper presents case studies and lecture notes on a specific constituent of linear programming, and which is the part relating to sensitivity analysis, and, particularly, the %Author: Samih Antoine Azar.

This topic is commonly called sensitivity analysis. We discuss the question of adding variables or constraints to the problem in Section Sections and discuss parametric programming, which concerns more extensive changes to the data that are parametrized by a single variable.

Again, we consider only changes to the cost vector. Sensitivity Analysis SA presents a post optimality investigation of how a change in the model data changes the optimal solution. SA allows decision makers to determine how “sensitive” the optimal solution is to changes in data values.

Key words: Linear programming, Integer Programming, Sensitivity analysis, production planning 1. Introduction. Chapter 6: Sensitivity Analysis Suppose that you have just completed a linear programming solution which will Sensitivity analysis in linear programming book a major impact on your company, such as determining how much to increase the overall production capacity, and are about to present the results to the board of directors.

How confident are you in the results. Sensitivity analysis in linear programming studies the stability of optimal solutions and the optimal objective value with respect to perturbations in the input : Carlo Filippi.

Sensitivity (Or Postoptimality) Analysis Following formulation and solution of a linear programming problem, it frequently is important to consider variations in the coefficients of the variables in the objective function and/or constraints, and/or resources (right-hand sides).

Sensitivity Analysis deals with finding out the amount by which we can change the input data for the output of our linear programming model to remain comparatively unchanged.

This helps us in determining the sensitivity of the data we supply for the problem. Linear Programming: Sensitivity Analysis and Interpretation of Solution CHAPTER 8 QUANTITATIVE TECHNIQUES IN BUSINESS AC Sensitivity Analysis Is the study of how changes in the coefficients of a linear programming problem affect the optimal solution.

Specifically, we shall undertake a sensitivity analysis of the initial linear programming problem, i.e. this sort of post‐optimality analysis involves the introduction of discrete changes in any of the components of the matrices, in which case the values of c j, b i, or a ij, i = 1,m; j = 1,n − m, respectively, are altered (increased or decreased) in order to determine the extent to which the original problem may be.

Sensitivity theorems in integer linear programming. The recognition of patterns in linear programming solutions is a way of looking beyond the specific numbers in the result and toward a broader economic imperative. By focusing on positive decision variables and binding constraints, this interpretation emphasizes the key factors in the model that drive the form of the solution.

4 SENSITIVITY ANALYSIS IN LINEAR PROGRAMS. As described in Chapter 1, sensitivity analysis involves linking results and conclusions to initial a typical spreadsheet model, we might ask what-if questions regarding the choice of decision variables, looking for.

Journals & Books; Help; COVID campus The paper starts giving the main results that allow a sensitivity analysis to be performed in a general optimization problem, including sensitivities of the objective function, the primal and the dual variables with respect to data.

general results are given for non-linear programming, and closed Cited by: This paper will cover the main concepts in linear programming, including examples when appropriate.

First, in Section 1 we will explore simple prop-erties, basic de nitions and theories of linear programs. In order to illustrate some applicationsof linear programming,we will explain simpli ed \real-world" examples in Section 2.A separate model is solved for each variation of the transport cost matrix.

The transport cost on each link is raised and lowered by 30 percent and the shipment patterns are either saved in a GAMS data table or written to file for further analysis by a statistical system.
