Abstract

Atualmente, dois dos grandes desafios com os quais o agronegócio brasileiro, responsável por aproximadamente 33% do PIB nacional (SECEX, 2005), se depara em seu constante crescimento são a alta dependência de produtos químicos (fertilizantes) para que sua fronteira agrícola se expanda e, conseqüentemente, as enormes distâncias (e custos de transportes) que essas fronteiras impõem para que sejam vencidas, tanto para o recebimento de insumos de produção, quanto para o fornecimento de seus produtos finais. Particularmente, a região Centro-Oeste brasileira, formada pelos Estados de Goiás, Mato Grosso, Mato Grosso do Sul e Distrito Federal, se enquadra em ambos os pontos – possui grandes fronteiras agrícolas a serem exploradas e, ao mesmo tempo, se localiza a grandes distâncias dos principais portos de escoamento de sua produção e aquisição de insumos (especialmente, adubos e fertilizantes). Dentro deste contexto, o presente trabalho teve como objetivo, através da elaboração de um modelo matemático de programação linear, indicar localizações para instalação de fábricas misturadoras de adubos que minimizem os custos de transporte envolvidos. Portanto, de forma geral, os dados levantados para a realização desse estudo dizem respeito, basicamente, aos custos de transportes envolvidos com a distribuição de matéria-prima e produto final entre os municípios envolvidos, bem como suas respectivas necessidades de consumo e capacidade de fornecimento. Observou-se, a partir dos resultados gerados, uma tendência bastante clara de instalações de fábricas misturadoras em locais que o acesso às matérias-primas envolvidas no processo produtivo se caracterizasse pela facilidade e pelo baixo custo. Um outro ponto bastante evidente nos resultados observado é a participação do modal ferroviário no processo de distribuição das principais matérias-primas.-------------------------------------------------------------------------------------- Currently, the Brazilian agribusiness is responsible for about 33% of the national PIB (SECEX, 2005) and face up to two of the great challenges in its constant growth which are the high dependence of chemical products (fertilizers) to expand its agricultural frontier and consequently, the big distance (and transports costs) that this frontiers impose to be overcome, as much for the receiving of production input as the supply of its final products. Particularly, the Brazilian center-west region, formed by the States of Goiás, Mato Grosso, Mato Grosso do Sul and Distrito Federal, is inserted in both the points, has greats agricultural frontiers to be explored and in the same time, is located so far of the main draining ports of its production and acquisition of inputs (specially fertilizers). Inside of this context and thought the elaboration of a mathematic model of linear programming, the present work had as objective to indicate localizations for mixers fertilizers plants installation which minimize the involved transport costs. Therefore, in general form, the data raised for the accomplishment of this study means of the involved transports costs with the distribution of raw material and final product between the involved cities, as its respective needs of consumption and supply capacity. With the results was observed a sufficiently clear tendency of mixers plants installation in locals where the access of raw materials involved in productive process was characterized by facility and low cost. Another evident point in the results is the participation of railway modal in the distribution process of the main raw materials.
