Location model of specialized terminals for soybe an exports in Brazil

Abstract

ABSTRACT. The purpose of this work is the development of a location model for specialized terminals used as transshipment points in the supply chain of soybeans. The theoretical basis of the study relies on the association of a transshipment model with a multi-commodity, multi-facility capacitated location model. The shipping ports might be seen as specialized terminals that add value to the exported products by transforming raw soy grains into soy oil and soy meal. The proposed model also considers service activities in each terminal and the capacity of the maritime ports. Using representative data from the year 2004, the model is illustrated by a small case study, which considers six points of production in inland Brazil, all served by railways, one maritime port on the north and five on the east coast, and three destination ports in Europe and Asia. The study includes a rough sensitivity analysis regarding volumes, capacities, prices, and transportation costs.

Models and Methods for Logistics Hub Location: A Review Towards Transportation Networks Design

“…On the other hand,Škrinjar, Rogić & Stancović (2012) point out the importance of studying network topologies where transportation can be done either via hub or by direct connections, which are scarce in the literature. According to Dubke & Pizzolato (2011), future research should also look at network design and infrastructure planning, comprising a variety of transportation modes such as road-, rail-and waterways. In addition, the impacts of a new hub on the network should be further explored Farahani et al (2013).…”

“…According to Gao & Dong (2012) and Dubke & Pizzolato (2011), logistics hubs should be located at the intersection of large streams of flow, or very close to major transport links, especially in order to take advantage of multimodality. In addition to ensuring the existence of a greater volume of cargo that could be handled in the hub, this would encourage a better use of the Defining the initial set of potential location sites could also be based on criteria related to the location of supply and demand of goods.…”

“…Among these, the most common ones pursue costs minimization, either of transportation or total costs. Dubke & Pizzolato (2011), on the other hand, aim at maximizing the revenue. Other goals might also be related to minimizing the travelled distances, which could be indirectly related to financial results, as well as service level and market coverage.…”

“…Already in 1994, Izquierdo (apud Dubke & Pizzolato, 2011) pointed out that among the criteria which impact logistics hubs design, the location seemed to be a crucial decision element. The choice of site affects the success not only of operational activities itself (Tu et al, 2010), but also of supply chain management and of transportation network planning, ultimately influencing the distribution systems as a whole (Melo, Nickel & Saldanha-da-Gama, 2009;Škrinjar, Rogić & Stancović, 2012).…”

“…The model determines the least-cost strategy for an importer, in terms of ports and inland transportation modes to be used, considering costs for transportation and handling. Dubke and Pizzolato [39] developed a model for a case defining ports for the export of soybeans in Brazil. The proposed model also considers service activities and the capacity of the maritime port.…”
