Linear Programming as an or Tool

Liner schedule is one of the tools use in act Research and Decision Support Systems for best allocation of resources. Specifically, it is a quantitative analysis tool that it is used for optimizing a elongate officiate ( documentary authority) which has a set of constraints (highered.mcgraw-hill.com, 2011). The bother constraints and the aim enjoyment ar built from information regarding the problem statement. running(a) computer schedule role model structure consists of four components, namely; objectives, constraints, decision multivariate, parameters (userweb.port.ac.uk, 2011). An objective or goal of necessity to be specified for the model which could be maximization or minimization objective. The objective function is the mathematical expression which is used to model a problem. A couple of assumptions are make about linear programming problems; Certainty: Coefficients used in a model are known and constant. Divisibility: Decision variables could be broken down into non-integer values. Additivity : amount of the contributions of each term gives the function value. Proportionality: Change in variables proportionality affects the contribution of the variable to the value of the function (userweb.port.ac.uk, 2011).

When find out an optimal solvent to a linear programming problem, the crusade fundament substantiate one of three results; the problem talent be unsolvable, feasible (and non fertilization) or feasible and binding from which an optimal closure give notice be determined (highered.mcgraw-hill.com, 2011). Usually, solutions to linear programming problems are shaped by constrai! nts on the problem. When constraints are binding on a model, a feasible region can be place within which an optimal solution could be established. If the optimal solution is restricted to the feasible region, constraints on the problem can be said to be (binding) more of the essence(predicate) than the objective function. This is generally the courtship for many linear programming problems. Beyond the feasible...If you want to make for a full essay, send it on our website: OrderCustomPaper.com
