Operation Research

Hi friends!!!

   Today let's discuss about topic LINEAR PROGRAMMING PROBLEMS of operation research (OR)

There are 3 methods to solve it
1) simplex method
2) big M method
3) graphical method
 

~> Today we will discuss about simplex method. In this method, objective function is given which is subjected to some equations wich are '<= 'type  equations..

~»steps to solve LPP problems:

->  convert  given equations (<= type) in stadard form ( means convert <= into =)
By introducing slack variable S)

Example: if give equation is       2x+5y+6z  <=  5 .... then it will be converted into.   2x+5y+6z+S = 5

-> after convert all eqation in stadard form tabulate em and solve prblm. And how to tabulate em is a different point to discuss.. maybe later
