After all through discussion I conclude how every methods of every models. Using the proper way of solving it step by step. Specifically, I learn how to plot every given numbers in a graph which is graphical method. I also learn how to use graphical method in a problem solving to know if its balance or imbalance. Also the step by step on solving simplex method with every tableau used. The duality and sensitivity which is the harder version of the simplex method. The 3 ways of solving in transportation model which is North West Corner Rule, it is solve by using the ladderize method. Basically I was applied as it called you solve it in a ladderize form one by one. The Greedy / Minimum Cost Method which is solve by beginning to lowest unit cost up until the highest it gets and until the supply and demand is already 0’s. The Vogel’s Approximation Method which is solve using the unit cost table. Somehow it may have the same answer in Greedy Method because the main solution of this method is also by beginning into the lowest. I acknowledge all the methods and solution but if it’s been discussed already a long time ago i forgot it.
