Question

When capacity and demand are not equal in transportation problem?

Answer 1

demand and supply are not equal in a transportation problem then the problem can be reformulated and solved. 8.The linear programming model for a transportation problem has constraints for supply at each source and demand at each destination. 9.In a balanced transportation model where supply equals demand, all constraints are equalities . 10.In the linear programming formulation of the transshipment problem there is one constraint for each node. 11.Transportation problems are concerned with distributing commodities from sources to destinations in such a way as to maximize the total amount shipped. 12.The transportation model is a special type of linear regression model. 13.A dummy origin is used when the supply is greater than the demand. 14.When an empty cell is filled artificially in order to complete a degenerate solution of the transportation model, the filled cell is called a dummy. 15.In a transportation problem, items are allocated from sources to destinations at a maximum cost. 16.The purpose of the transportation approach for locational analysis is to minimize total costs . 17.The initial solution to a transportation problem can be generated in any manner, so long as all cells are filled. 18.A transportation problem has a feasible solution when the solution yields the lowest possible cost. 19.The objective of the transportation problem is to minimize the number of shipments necessary to satisfy total demand at the destinations. 20.A transportation problem with 3 sources and 4 destinations will have 7 decision variables.
