In Somenath24/TransP: Implementation of Transportation Problem Algorithm

Description Usage Arguments Details Value Examples

This function implements North-West Corner Algorithm to solve transportation problem by optimized cost matrix and total optimized cost

1 2	# Get optimized cost matrix for input matrix ex_matrix nwc(ex_matrix)

ex_matrix

A cost matrix where last column must be the supply and last row must be the demand. Input matrix should not have any missing values (NA), otherwise function will throw an error.

This function takes a cost matrix (with Supply and Demand) and using North-West Corner approach gives the cost allocation matrix as well as the calcualted optimized cost. This function checks for degenerated problem but it can't resolve it. User need to resolve by seeing the cost allocation matrix.

A List which contrains the Cost allocation matrix and the total optimized cost.
