Linear programming From Wikipedia, the free encyclopedia Jump to: navigation search Linear programming LP ) is a mathematical method for determining a way to achieve the best outcome (such as maximum profit or lowest cost) in a given mathematical model for some list of requirements represented as linear equations. More formally, linear programming is a technique for the optimization of a linear objective function , subject to linear equality and linear inequality constraints . Given a polytope and a real -valued affine function defined on this polytope, a linear programming method will find a point on the polytope where this function has the smallest (or largest) value if such point exists, by searching through the polytope vertices. Linear programs are problems that can be expressed in canonical form where x represents the vector of variables (to be determined), c and b are vectors of (known) coefficients and A is a (known) matrix of coefficients. The expression to be maximized or minimized is called the objective function c T x in this case). The equations

Navigation index next previous Sage Constructions v4.5.3 Linear Programming Basics What is a linear program? A linear program consists of the following two pieces of information: A linear function, called the objective function, which is to be maximized or minimized, e.g. Linear constraints on the variables, e.g. and A linear program solver would then try to find a solution to the system of constraints such that the objective function is optimized, and return specific values for the variables. What is a mixed integer linear program? A mixed integer linear program is a linear program such that some variables are forced to take integer values instead of real values. This difference affects the time required to solve a particular linear program. Indeed, solving a linear program can be done in polynomial time while solving a general mixed integer linear program is usually -complete, i.e. it can take exponential time, according to a widely-held belief that Why is linear programming so useful? Linear programming is very useful in many optimization and graph-theoretic problems because of its wide range of expression. A linear program can be written to solve a problem whose solution could be obtained within reasonable time using the wealth of heuristics already contained in linear program solvers. It is often difficult to theoretically determine the execution time of a linear program, though it could produce very interesting results in practice.

Linear Programming A linear program is a mathematical optimization model that has a linear objective function and a set of linear constraints. To provide a quick overview, we describe below what is known as the product-mix problem. The Product-Mix Problem A company manufactures two models of a product, which we call the regular model and the enhanced model. Two resources, A and B, are needed for the manufacturing of units of this product; and the detailed resource requirements are given in the following table: Regular Model Enhanced Model Resource A Resource B This means, for example, 3 units of Resource A and 2 units of Resource B are consumed in the manufacturing of each unit of the regular model. The resources could represent hours of labor, amounts of raw material, available electrical power, and so on. Suppose further that the company has 650 units of Resource A and 500 units of Resource B available per week, and that the net profits for selling units of the regular model and the enhanced model are given respectively as $5 and $7 per unit. The question of interest is: What are the optimal weekly production levels for these two models? To formulate this problem, we first define a set of decision variables. Let

Linear programming - Definition In mathematics, linear programming (LP) problems are optimization problems in which the objective function and the constraints are all linear Linear programming is an important field of optimization for several reasons. Many practical problems in operations research can be expressed as linear programming problems. Certain special cases of linear programming, such as network flow problems and multicommodity flow problems are considered important enough to have generated much research on specialized algorithms for their solution. A number of algorithms for other types of optimization problems work by solving LP problems as sub-problems. Historically, ideas from linear programming have inspired many of the central concepts of optimization theory, such as duality, decomposition, and the importance of convexity and its generalizations.

Operations Research/Linear Programming From Wikibooks, the open-content textbooks collection Operations Research This page may need to be reviewed for quality. Jump to: navigation search Linear Programming (LP) is a mathematical modelling technique useful for allocation of limited resources such as material, machines etc to several competing activities such as projects, services etc. A typical linear programming problem consists of a linear objective function which is to be maximized or minimized subject to a finite number of linear constraints. (By a linear function we mean a function of the form where are all variables.) The founders of LP are George B. Dantzig, who published the simplex method in 1947, John von Neumann, who developed the theory of the duality in the same year, and Leonid Kantorovich, a Russian mathematician who used similar techniques in economics before Dantzig and won the Nobel prize in 1975 in economics. The linear programming problem was first shown to be solvable in polynomial time by Leonid Khachiyan in 1979, but a larger major theoretical and practical breakthrough in the field came in 1984 when Narendra Karmarkar introduced a new interior point method for solving linear programming problems. edit The Two Variable LP model Two variable LP models don't usually exist in practice but their study can provide us with an example as to how a general model can be handled.

Linear Programming From NEOS Jump to: navigation search Software for linear programming (including network linear programming) consumes more computer cycles than software for all other kinds of optimization problems combined . There is a proliferation of linear programming software with widely varying capabilities and user interfaces. The most recent survey of linear programming software for desktop computers carried out by OR/MS Today (19 (1992), pp. 44-59) gave details o n 49 packages! The basic problem of linear programming is to minimize a linear objective functi on of continuous real variables, subject to linear constraints. For purposes of describin g and analyzing algorithms, the problem is often stated in the standard form where x is the vector of unknowns, c is the cost vector, and A is the constraint matrix. The feasible region described by the constraints is a polytope, or simplex , and at least one member of the solution set lies at a vertex of this polytope. The simplex algorithm , so named because of the geometry of the feasible set, underlies the vast majority of available software packages for linear programming. However, this situation may change in the future, as more software for interior-point algorithms becomes available.

Notes Problems 1 Problems 2 Algebra ... Problems Linear Programming Word Problems A company manufactures and sells two models of lamps, L1 and L2. To manufacture each lamp, the manual work involved in model L1 is 20 minutes and for L2, 30 minutes. The mechanical (machine) work involved for L1 is 20 minutes and for L2, 10 minutes. The manual work available per month is 100 hours and the machine is limited to only 80 hours per month. Knowing that the profit per unit is $15 and $10 for L1 and L2, respectively, determine the quantities of each lamp that should be manufactured to obtain the maximum benefit. With the start of school approaching, a store is planning on having a sale on school materials. They have 600 notebooks, 500 folders and 400 pens in stock, and they plan on packing it in two different forms. In the first package, there will be 2 notebooks, 1 folder and 2 pens, and in the second one, 3 notebooks, 1 folder and 1 pen. The price of each package will be $6.50 and $7.00 respectively. How many packages should they put together of each type to obtain the maximum benefit? On a chicken farm, the poultry is given a healthy diet to gain weight. The chickens have to consume a minimum of 15 units of Substance A and another 15 units of Substance B. In the market there are only two classes of compounds: Type X, with a composition of one unit of A to five units of B, and another type, Y, with a composition of five units of A to one of B. The price of Type X is $10 and Type Y, $30. What are the quantities of each type of compound that have to be purchased to cover the needs of the diet with a minimal cost?
