LG has established a distribution network for the supply of dishwashers from its three plants to three Warehouses. The current network has the following characteristics:

$\backslash$table$[[$COSTS$,$Noida,Surat,Puri,Supply$],[$Plant$1,7,4,3,700],[$Plant$2,8,6,12,500],[$Plant$3,10,9,9,600],[$Demand$,550,650,600,]]$

The unit costs, supply and demand are given in the table. Apply NWC method to identify the initial feasible solution and further identify optimal solution.
