Today,it’s hard to imagine a transport world without short sea shipping.Not only does this modern version of coastal shipping experience no delays due to road congestion,low road assessment,also has the lowest transportation cost and co2 emission of all commercial transport modes.For these reasons,short sea shipping is in many cases a perfect alternative to road transport.In this research paper we designed an optimal transportation method of short sea shipping in Yemen to lower the country transportation cost of commercial goods,since Yemen is unfavorable in terms of transportation infrastructure,hard level of mountainous areas and roads are generally poor,short sea shipping is a great alternative to road transport.We collected data and computed the cost of short sea shipping in a multi stage method(warehouse and distribution centers) saving an average of 40% to 50% of transportation cost than if delivered by direct road to road.This research paper and its methodologies have favorable results in all studied aspects.
