very user friendly. The software can be executed in automated or tutorial mode. The automated mode reports the final solution of the problem‚ usually in the standard format followed in commercial packages‚ while the tutorial mode keeps on giving step-wise information about the methodology and solution. TORA tutorial software deals with the following algorithms: •Solution of simultaneous linear equations •Linear programming •Transportation

Method Learning outcomes • The Big M Method to solve a linear programming problem. In the previous discussions of the Simplex algorithm I have seen that the method must start with a basic feasible solution. In my examples so far‚ I have looked at problems that‚ when put into standard LP form‚ conveniently have an all slack starting solution. An all slack solution is only a possibility when all of the constraints in the problem have or = constraints‚ a starting basic feasible solution may not be readily

firm manages her inventory to gain minimum production cost and earn business success by using JIT (Just in Time) Manufacturing System. It provides a mathematical framework to understand the performance of a farm‚ and argues that inventory cost minimization method is an approach that helps a farm to be competitive and successful. JIT inventory management system has been elaborated by reducing set-up times and lead times so that small lots may be ordered as and when required. The holding cost for space

About the Music Video Both Jay-Z’s third single album “99 Problems” and its corresponding music video were released in 2004. Although Jay-Z is known today as a famous rapper and a producer of Roc-A-Fella record label‚ he did not start off with the most fortunate setting. The music video portrays the ghetto of Brooklyn‚ New York in the 1990s and illustrates the struggles that Jay-Z had to go through during his career in order to reach the top of the music industry.
