Shore 1970 2 have developed the transportation problem and the vogel s approximation method. The vogel s approximation method or vam is an iterative procedure calculated to find out the initial feasible solution of the transportation problem. The modi and vam methods of solving transportation problems. Initial basic feasible solution by vam vogels approximation method of transportation problem duration. In the previous section, we used vogel approximation method unit cost penalty method to solve a transportation problem. Pdf transportation problem in operational research. Vogels approximation method transportation problem youtube. Vogel approximation method transportation algorithm in lp.
Lets concentrate on the following example and find the optimal solution. A variant of vam was proposed by using total opportunity cost and regarding alter native allocation costs. Three methods north west corner method nwcm, least cost method lcm and vogels approximation method vam have been used to find initial basic feasible solution for the transportation model. In this section, we provide another example to enhance your knowledge. Pdf modified vogels approximation method for solving. Vogel approximation method examples, transportation problem. This tutorial deals with two techniques for solving transportation problems.
