## How do you solve LPP by graphical method?

The Graphical Method

1. Step 1: Formulate the LP (Linear programming) problem.
2. Step 2: Construct a graph and plot the constraint lines.
3. Step 3: Determine the valid side of each constraint line.
4. Step 4: Identify the feasible solution region.
5. Step 5: Plot the objective function on the graph.
6. Step 6: Find the optimum point.

### What is graphical method?

Graphical method, or Geometric method, allows solving simple linear programming problems intuitively and visually. This method is limited to two or three problems decision variables since it is not possible to graphically illustrate more than 3D.

How do you calculate LPP?

Answer: In order to calculate LPP, one must follow the following steps:

1. Formulate the LP problem.
2. Construct a graph and then plot the various constraint lines.
3. Ascertain the valid side of all constraint lines.
4. Identify the region of feasible solution.
5. Plot the objective function.
6. Finally, find out the optimum point.

What is graphical method in operation research?

The graphical method represents an optimization algorithm for solving linear programming problems containing two decision variables (x1 and x2). It is one of the most popular approaches for solving simple linear programming problems.

## How many variables can be solved in graphical method?

two variables
With graphical methods, any optimization programming problems consisting of only two variables can easily be solved.

### How many variables can be used in a graphical method Why?

What is graphical method example?

Graphical Method Examples Example 1: The path of highway number 1 is given by the equation x + y = 7 and the highway number 2 is given by the equation 5x + 2y = 20. Represent these equations geometrically. Plot the points A (1, 6), B(4, 3) and join them to form a line AB. Similarly, plot the points C(2, 5).

Why graphical method is used?

Graphical methods are commonly used for determining whether the data support an interpretation of mixing of two potential sources or fractionation of a single source.

## What are the two forms of LPP?

3.2 Canonical and Standard forms of LPP : Two forms are dealt with here, the canonical form and the standard form.

### What are the uses of LPP?

LPP applications may include production scheduling, inventory policies, investment portfolio, allocation of advertising budget, construction of warehouses, etc. In this article, we would focus on the different components of the output generated by Microsoft excel while solving a basic LPP model.

What are the applications of LPP?

LPP applications may include production scheduling, inventory policies, investment portfolio, allocation of advertising budget, construction of warehouses, etc.

What is the other name for graphical method?

A scatter diagram (also called a scatter plot) is a graphical method using cartesian coordinates to represent the data values for two variables (X, Y).
