Cantrex wants to determine the least costly flow of materials and goods along this supply chain that will meet the demand at the U.S. distribution centers. Develop a transshipment supply chain model for Cantrex that will result in a minimum cost solution.

Cantrex Apparel International manufactures clothing items around the world. It has currently contracted with a U.S. retail clothing wholesale distributor for men’s goatskin and lambskin leather jackets for the next Christmas season. The distributor has distribution centers in Ohio, Tennessee, and New York. The distributor supplies the leather jackets to a discount retail chain, a chain of mall boutique stores, and a department store chain. The jackets arrive at the distribution centers unfinished, and at the centers the distributor adds a unique lining and label specific to each of its customers. The distributor has contracted with Cantrex to deliver the following number of leather jackets to its distribution centers in late fall.
