Inventory Routing Problem with a Transshipment Option

This paper investigates the Inventory Routing Problem where multiple capacitated vehicles distribute products from multiple suppliers to a single plant, and the final products produced to customers over a finite planning horizon. The demand associated with each product is assumed to be deterministic and time varying. In this supply chain, the products are assumed to be ready for collection at the supplier site when the vehicle arrives. A transshipment option is considered as a possible solution to increase the performance of the supply chain and shows the impact of this solution on the environment. A green logistic issue is also incorporated into the model by considering the interrelationship between the transportation cost and the greenhousegasemission level. The proposed model is a mixed-integer linear program that solved by GAMS software and the results is explained. The computational results show that the proposed model generates high quality schedules in a timely fashion
