Abstract The fixed charge transportation problem generalizes the well-known transportation problem where the cost of sending goods from a source to a sink is composed of a fixed cost and a continuous cost proportional to the amount of goods sent. Supply (\(\textit{n}\)) and demand (\(\textit{m}\)) are generally represented as unit weights of decision variables at facilities along a network with the time or distance between nodes representing the cost of transporting one unit from a supply node to a demand node. To review, open the file in an editor that reveals hidden Unicode characters. This article is about examples and solutions of the optimal transport problem with Python and Tableau.
