How to solve Unbalanced Transportation problem of maximization type?(Apr 2002) (Apr 2005)
Transportation is a minimization model. First, we should balance the problem by taking dummy where necessary (i. e. either on Supply side or Demand side). After balancing the problem, we should convert the problem in Minimization by converting it into Regret matrix.
To find Regret matrix, find maximum profit value in the original matrix. From this maximum profit value, subtract all profit values in the matrix. The resulting matrix is Regret matrix.
Very useful.
