Simulação do escoamento da produção de milho, soja e trigo dos núcleos regionais de Cascavel e Toledo

Abstract

In the West of Paraná State, the Regional Nuclei of Agricultural State Secretary SEAB - are located in Cascavel and Toledo. The first one has an area of 1,283,062.58 ha, which includes 28 cities; the second one is 849,732.80 ha wide and counts with 20 cities. These Regional Nuclei are responsible for twenty percent of the Whole Production Value, requiring agribusiness state production, as well as important areas concerning/ corn, soybean at wheat production; and they reach almost 4.8 millions tones/grains per year. In order to spread out this production, railways and roadways are employed, even though it decisionmaking affects traffic conditions and implies in costs. Researches Operations tools can be applied, which aims are evaluation, management and planning to improve transportation system use Among these tools, it can be mentioned the simulation practice, which, by means of computational models, helps on choosing how the experiment will be carried out, such as: (i) sensitivity analyses; (ii) scenario analyses, (iii) optimization; and (iv) Monte Carlo Simulation. Considering these potentialities, this trial was carried out aiming at implementing a computational model to simulate grains and oilseeds transportation from the Regional Nuclei of Cascavel and Toledo, respectively. This simulation concerned about 2003, 2004 and 2005 years; and sensitivity analysis was also conducted considering changes of percentage indexes related to the loads destination to roadways and railways, respectively. The applied model showed a great potential for supporting management of grains and oilseeds transportation system, with diversity of reports and information. For example, in 2004, at Cascavel Regional Nucleus, 2,2 millions tonnes of products were processed, with a consumption of 44.916,74 m-3 of firewood, and 34.489 transportations were also made from Cascavel to Paranaguá Port using the roadway
