Inventory Routing Problem with a Transshipment Option

چکیده مقاله

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 greenhousegas
emission 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.
