Software para estimativa do custo operacional de máquinas agrícolas - MAQCONTROL

Abstract

RESUMO:A seleção e a otimização de sistemas mecanizados são os principais objetivos da mecanização racional. Não é suficiente uma compra adequada do maquinário agrícola se sua utilização não for controlada em aspectos operacionais e financeiros. Neste trabalho, é descrito o desenvolvimento de software para estimativa do custo operacional de máquinas agrícolas (MAQCONTROL), utilizando o ambiente de desenvolvimento Borland Delphi e o banco de dados Firebird. Os custos operacionais foram divididos em fixos e variáveis. Nos custos fixos, foram estimadas as despesas com depreciação, juros, alojamento e seguros. Nos custos variáveis, foi dada ênfase aos custos de manutenção como: óleos lubrificantes, filtros, pneus, graxa, combustível, pequenos reparos e troca de peças. Os resultados demonstraram a eficiência do software para os objetivos propostos. Assim, o MAQCONTROL pode ser uma importante ferramenta no processo de administração rural, pois reduz os custos da informação e agiliza a determinação precisa dos custos operacionais de máquinas agrícolas.

DEVELOPMENT OF SOFTWARE TO COMPUTE OPERATIONAL COSTS OF FARM MACHINERY -MAQCONTROL ABSTRACT:The rational mechanization has as main objectives the selection and optimization of mechanized systems. An adequate purchase of agricultural machinery is not sufficient if its use is not controlled in operational and financial aspects. This work describes the development of software to estimate operational costs of agricultural machinery (MAQCONTROL), using Borland Delphi's development environment and Firebird database. The operational costs were divided in fixed and variable. In fixed costs, the expenses with depreciation, interest, storage and insurance were estimated. In variable costs, the emphasis was given to the expenses on maintenance, lubricating oils, filters, tires, grease, fuel, small repairs, and parts replacement. Results have shown the software efficiency for the proposed objectives. Therefore, the MAQCONTROL software proved to be an important tool in the rural management process, because it reduces information costs and accelerate the precise determination of operational costs of farm machinery.

“…Because of this, it is important to monitor mechanization considering operational and financial aspects (Piacentini et al, 2012).…”

Optimization Model for Vehicle Routing and Equipment Replacement in Farm Machinery

“…Considering cost models applied to farm machinery, Mercante et al (2010) and Piacentini et al (2012) developed computational tools based on farm costs divided into fixed (depreciation, interest, housing, insurance) and variable (fuel, lubricant, tires, grease, parts replacement). These models were developed to determine, respectively, the cost of farm operation (including labor) and the operating costs of farm machinery.…”

“…Therefore, in the properties that use mechanization in the production, the monitoring of the work done by agricultural machines and implements should deserve more attention (Sichonany et al, 2011). An adequate purchase of agricultural machinery is not enough if its use is not monitored in operational and financial aspects (Piacentini et al, 2012).…”
