Comparison of Performance of VAM and its Modifications in Case of Transportation and Trans-Shipment Problems

This research paper is about the comparison of performance of Vogel’s Approximation method over its modifications using three key measures which are average iteration, number of best solutions, and computational time. The greater the performance of improved VAM technique, more effective the method will become to find out the optimum cost in case of transportation and trans-shipment problems. The characteristics of both IVAM and VAM methods varies with the size of the problem. The average iteration for a bigger sized problem effects the computational time. The use of total opportunity cost matrix and its effect on the computational time is shown in this paper. The appropriate method based on the problem size is also predicted in this paper.
