A decision support system for cost determination in grain storage facility operations

Abstract: Many research works have being carried out on analyzing grain storage facility costs; however a few of them had taken into account the analysis of factors associated to all preprocessing and storage steps. The objective of this work was to develop a decision support system for determining the grain storage facility costs and utilization fees in grain storage facilities. The data of a CONAB storage facility located in Ponta Grossa -PR, Brazil, was used as input of the system developed to analyze its specific ch… Show more

“…11 Just as important as the technical factors is the drying economic feasibility, which can be evaluated by an economic analysis performed with the main objectives of verifying all the project risks and minimizing investment failures. 12,13 One of the tools used for performing this analysis is the cash flow model, representing a balance of the amount of revenues and expenses of an investment during the lifetime of the project, and indicating its feasibility by economic indices. 14 Several authors already evaluated the economic feasibility of grain drying by simulations, but they considered products, dryers and, bulk volumes in isolation, as well as short project lifetimes.…”

“…This concept can be applied to grain drying projects. For this, careful economic analyses are required, considering all the risks involved in this process and searching for strategies that minimize investment failures (Valente et al, 2011;Mugabi and Driscroll, 2016).…”

“…Jasper et al (2006) simulated the economic feasibility of investing in small in-bin dryers, considering the State of São Paulo (Brazil) and the storage of maize, concluding that this is a profitable option, provided that the selling price of maize is greater than the annual costs of the system. Valente et al (2011) developed a decision support system to determine the costs and rates of unit operations regarding reception, cleaning, drying, storage and dispatch of grains in storage facilities. These authors considered high-temperature drying and focused specifically on the South region of Brazil.…”

“…CENTENO & KAERCHER (2010) relatam que os custos referentes à mecanização das operações agrícolas, nas diferentes culturas, representam entre 10 e 30% dos custos totais de produção, demonstrando a importância da escolha do equipamento mais adequado para o processo produtivo. VALENTE et al (2011) elaboraram um programa de apoio à decisão para a determinação dos custos em unidades armazenadoras de grãos e verificaram que este trouxe flexibilidade ao suporte à decisão. QI et al (2009) desenvolveram um programa computacional para uma análise estatística do uso da maquinaria agrícola em uma região da China e verificaram que o uso deste programa permitiu uma análise contínua mais eficiente ao longo do tempo.…”
