LPP - Linear programming problem Conclusion

The graphical method of solving an LPP is possible only if there are two decision variables (say x and y). This method is not suitable if there are three or more decision variables. In this case, there is a powerful method called 'simplex method'. The wide usage of liner programming helps in business and economics, to use the resources available in a planned and economical way. We have just learnt the basics of LPP, there is in fact a lot to learn in higher classes. A lot of research work is carried all over the world which is based on LPP.
