SOLVING LINEAR PROGRAMMING GRAPHICALLY USING COMPUTER in Quantitative Techniques for management

After potting the above graphs, we know the range of x and y that will satisfy all the given conditions. Extreme point Coordinates x,y Objective value Z O 0,0 0 C 0,14 28 G 3,12 33 H 6,6 30 F 8,0 24 Graphical method and Simplex method comparison Successive constructed tableaux in the Simplex method will provide the value of the objective function at the vertices of the feasible region, adjusting simultaneously, the coefficients of initial and slack variables. Solve the linear programming problem by the simplex method. Let us begin with the set of constraints and consider them as a system of inequalities. To demonstrate the applicability of the developed method, an agricultural water management problem has been provided in the case study section.

Also solve the problem using computer. The first row consists of the objective function coefficients, while the last row contains the objective function value and reduced costs Z j - C j. The shaded area corresponds with the domain of feasible solutions, where the optimal is reached at vertex C, where the budget and man-days restraints are active. If R is unbounded then the maximum and minimum value of Z may not exist, but if it exists, then it will occur at the corner point of region R.

Graphical Method of Solving Linear Programming Problems

Plot the lines on the graph as shown in Figure Here the objective is minimization. The initial tableau of Simplex method consists of all the coefficients of the decision variables of the original problem and the slack, surplus and artificial variables added in second step in columns, with P 0 as the constant term and P i as the coefficients of the rest of X i variables , and constraints in rows. The numbers in the ordered pair correspond to the variables in alphabetical order. The value of the remaining variable can then be found using simple algebra. Locate the point P, which lies on the x β axis. Now locate each of the vertices that fall on the border of this shaded area.

Graph Showing Feasible Area Example: A soft drink manufacturing company has 300 ml and 150 ml canned cola as its products with profit margin of Rs. Once obtained the input base variable, the output base variable is determined. The C b column contains the coefficients of the variables that are in the base. You may plot the constraints in the same manner as you would plot an equation. The optimal solution is given by the val-ue of Z in the constant terms column P 0 column , in the example: 33. Linear Programming Topic Contents Introduction Equation method can be used to solve linear programming problems with a greater accuracy than the. The solution of this system of inequalities is a set of points, S.

Move the objective function line away from the origin by drawing parallel lines. Graph Linear : A linear graph consists of a number of nodes or junction points, each joined to some or all of the others by arcs or lines. Unlike graphical method in which the coordinates of the optimum point are found by measuring directly from the graph, the equation method determines the precise coordinates by mathematically solving the two equations on which the optimum point lies. In this iteration, the output base variable is X 4 P 4.

In addition, the maximum amount of daily sales for the first product is estimated to be 200 units, without there being a maximum limit of daily sales for the second product. The objective is to maximize the profit.

Given the current availability of staff in the company, each day there is at most a total of 90 hours available for assembly and 80 hours for quality control. In some compa-nies, these various operations take place in differ-ent buildings, requiring materials to be transported James E. Then the optimal value maximum or minimum of Z will occur at a corner point vertex of the feasible region, provided that the optimal value of Z exists and where the x and y are subject to constraints described by linear inequalities.

Linear Programming Problems - Graphical Method Graphical Method of Solving Linear Programming Problems We already know how to plot the graph of any linear equation in two variables. Now, click the second equation to draw the second line on the graph. Therefore, the values of x 1 and x 2 are 100 and 0 respectively. In the problems involving linear programming, we know that we have more than one simultaneous , based on the conditions given and then we try to find the range of solutions based on the given conditions. Steps Inequalities are mathematical expressions similar to equations except for 1 difference. Step 4 Highlight the feasible region on the graph Once you have plotted the constraint inequalities on the graph, you need to shade the area of the graph which is outside the constraint limits, i.

The process involves plotting the points that satisfy the equation on the coordinate axis and joining them. Traditional Manufacturing Traditional manufacturing segregates different functional operations. Typi-cally, companies' products that can be produced in large quantities, and those that have a relatively long lead time between customer order and delivery can be manufactured overseas, while high-margin specialty items made in smaller quantities or those needing shorter lead times are manufactured in the United States. The intended audience is manufacturers of forest prod-ucts, although manufacturers of other types of prod-ucts will also find this publication useful. Pet business plan template business plan proposal format topic ideas for research papers topics for library research paper middle school homework policy detention assignments for middle school bibliography research paper in apa format. The graphs intersect at one point. Important: On the date of this publication we have more than 15 articles that deal with that we recommend you review, where we go over the graphical solution to these types of models as well as solutions that use algorithms like the and the computational implementation with tools such as and , among others.
