One of the advantages of the stepping-stone method is that if, at a particular iteration, we accidentally choose a route that is not the best, the only penalty is to perform additional iterations. 4) The transportation algorithm can be used to solve both minimization problems and maximization problems. 5) In the assignment problem, the costs for a dummy row will be equal to the lowest cost of the column for each respective cell in that row.
Multiple Choice Questions: 6) Which of the following techniques can be used for moving from an initial feasible solution to an optimal solution in a transportation problem? A) Hungarian method B) stepping-stone method C) northwest corner rule D) Vogel’s approximation method E) All of the above 7) After testing each unused cell by the stepping-stone method in the transportation problem and finding only one cell with a negative improvement index, A) once you make that improvement, you would definitely have an optimal solution.
B) you would make that improvement and then check all unused cells again. C) you could stop because you already had the optimal solution. D) you should check to be sure that you don’t have to add a dummy source or dummy destination. E) None of the above 8) If we want to quickly arrive at a “feasible,” but not necessarily “optimal” solution to the transportation problem, we will use the A) stepping-stone method. B) northwest corner rule. C) Vogel’s approximation method. D) MODI method. E) Any of the above ) If the total supply from the sources does not equal the total demand from the destinations in the transportation problem, A) and if supply is greater than demand, add a dummy source or factory. B) the amount put in a dummy source or destination should make supply and demand equal.
The Essay on Understanding problem and finding solution
The humans are supposedly the most intelligent creation of the nature. It has been its control over thought and logical reasoning capability that has made him the most powerful living species. Despite being less powerful if compared to other creatures like elephant and lion and also less productive than the plants and trees, the humans have managed to gain controlling authority on earth. The ...
