Find an initial basic feasible solution of the given transportation problem using northwest corner rule solution starting from the north west corner, we allocate 20 units to f 1 w 1. Lecture 15 outline •recap the last lecture •selection of the initial basic feasible solution northwest-corner method •computing reduced costs of nonbasic variables.
The north west corner rule is a method for computing a basic feasible solution of a transportation problem, where the basic variables are selected from the north – west corner ( ie, top left corner ). The least cost method is considered to produce more optimal results than the north-west corner because it considers the shipping cost while making the allocation, whereas the north-west corner method only considers the availability and supply requirement and allocation begin with the extreme left corner, irrespective of the shipping cost. Answer to (a) use the northwest-corner method to find an initial feasible solution to the following problem what must you do before beginning the solution steps (b) use.
