Partial sample average approximation method for chance. In this research, we have modified vogels approximation method mvam to find an initial basic feasible solution for the transportation problem whenever vam. The proposed method is easier, takes less computation time and gives better initial solution than vam method. Vogels approximation method is the most preferred method over the above two methods as it usually results in an optimal or a near optimal solution. In this study, vogels approximation method vam which is one of well known transportation methods in the literature was investigated to obtain more efficient initial solut ions. We can get an initial basic feasible solution for the transportation problem by using the northwest corner rule, row minima, column minima, matrix minima or the vogels approximation method. The idea behind eulers method is to use the tangentlinetothesolutioncurvethroughx0,y0toobtainsuchanapproximation. The vogel approximation unit penalty method is an iterative procedure for computing a basic feasible solution of a transportation problem.

Comparison of existing methods of solving linear transportation. Abstract scheme of the numericalanalytic successive approximation method for the sake of convenience, we present the basic features of the method in the following abstract form. Vogels approximation method vam file exchange mathworks. Numericalanalytic successive approximation method for non. This code has been designed to solve the transportation problem. A variant of vam was proposed by using total opportunity cost and regarding alter native allocation costs. With the northwest corner method, an initial allocation is made to the cell in the upper lefthand corner of the tableau i.

Pdf modified vogels approximation method for solving. In this section, we provide another example to enhance your knowledge. This article will discuss how to optimize the initial basic feasible solution through an explained example. Transportation problem set 6 modi method uv method.

Calculate a penalty for each row and column of the transportation table. The most common method used to determine efficient initial solutions for solving the trans portation problem using a modified version of the simplex method is.
