2018 POMS InternationalConference in Rio, Rio de Janeiro - Brazil 1 Analysis of Potential Demand for Agriculture Products at Itaqui Port in Brazil Mayumi P Hamaoka Business Department- Brasilia University Silvia Araujo dos Reis Business Department- BrasiliaUniversity Patrícia Guarnieri Business Department- BrasiliaUniversity Victor Rafael Celestino Business Department- BrasiliaUniversity José Márcio Carvalho Business Department- BrasiliaUniversity Abstract This paper presents the potencial demand at Itaqui Port for the three major groups of agriculture products exported by Brazil, in monetary values. A linear programming model was utilized, considering the shortest distance between origins, Brazilian State capitals, and destinies,the ten largest importing countries, passing through the port. Keywords: Brazilian ports,Itaqui Port,Mathematical Model, Agribusiness, Transportation. 1. Introduction Agribusiness is very important for Brazil, contributing with 23% of gross domestic product in 2017 (Ministry of Agriculture - MAPA, 2017). The abundant natural resources and the area available to expand food production make Brazil a competitive country in the agricultural area (CNA, 2018).However, the agricultural production gains can be limited by the lack of logistic planning and by the serious problems related to the poor infrastructure for the storage and transport of the agricultural production (Reis and Leal, 2015). This paper aims to contribute with the logistics planning for the agribusiness and transportation sectors, by estimating the potential demand for exports of agricultural products in the Port of Itaqui, at the MaranhaoState in Brazil, which is the sixth biggestport in Brazilian regardingeconomic transactions by sea in the year 2016, this according to data obtained from the Brazilian Ministry of Development, Industry and Foreign Trade - MDIC. Exports that occur through the waterway sector reached about 80% of the total monetary value exported by Brazil in 2017. The modal is highlighted by the vast coastal extension that the country has, allowing greater availability for the movement of cargo through this alternative. The estimation of ports demand can help in the planning of: actions for improvement in the port sector; infrastructural capacity; in the destination of internally originated products to their best port of export.
