Consider the transportation problem having the following parameter table:

		Destination				Supply
		1	2	3	4
Source	1	3	7	6	4	15
	2	2	4	3	2	12
	3	4	3	8	5	13
Demand		13	13	12	2

Use each of the following criteria to obtain an initial BF solution. In each case, interactively apply the transportation simplex method, starting with this initial solution, to obtain an optimal solution..

Compare the resulting number of iterations for the transportation simplex method Use northwest corner rule.
