Note: If the problem is not unbalanced then the concept of a dummy row or a dummy column to transform the unbalanced problem to balanced can be followed as discussed in this article. We will discuss the transportation problem first. Cross out the row or column which has satisfied supply or demand. These allocations should be independent positions in case of non-degenerate basic feasible solutions. Y. İlker Topcu, Prof. Dr. Acknowledgements: We would like to acknowledge Prof. W.L. The unit transportation cost of the commodity from each source to each destination. If the primal problem has n constraints and m variables then the number of constraints in the dual problem is _____. If a row and column are satisfied simultaneously, only cross out one of the two and allocate a supply or demand of zero to the one that remains. The transportation problem in operational research is concerned with finding the minimum cost of transporting a single commodity from a given number of sources (e.g. INITIAL BASICFEASIBLE SOLUTION 2.

Operations Research Problems Statements and Solutions. The level of supply at each source and the amount of demand at each destination. Here we are providing all the latest updates about the examination, strategy, previous year papers, syllabus, and many more. However, as soon as you expand and open a second warehouse, you will have to make an important decision: which warehouse will deliver which goods to each of your stores? Basic Feasible Solution : A feasible solution is called a basic feasible solution if it contains not more than m + n –1 allocations, where m is the number of rows and n is the number of columns in a transportation problem. Allocate as much as possible to the variable with the lowest unit cost in the selected row or column. The transportation problem in operational research is concerned with finding the minimum cost of transporting a single commodity from a given number of sources (e.g. View Transportation Problem Research Papers on Academia.edu for free. 4.

Transportation problem is considered a vitally important aspect that has been studied in a wide range of operations including research domains. Here, NorthWest Corner Method will be used. (1Operations Research Society of America). Since there is only one commodity, a destination can receive its demand from more than one source. After that, the computer analysis of these mathematical equations is done to find a solution for the problems, and then these solutions are applied to solve managerial and administrative problems. Adjust supply and demand for the non-crossed out rows and columns. Feasible Solution: A feasible solution to a transportation problem is a set of non-negative values x ij (i=1,2,..,m, j=1,2,…n) that satisfies the constraints.
