A aviação agrícola no Brasil: um modelo para seleção de aviões com o uso da programação linear

Abstract

The objective of this work is the optimization of the more viable model to the agricultural airplane for certain area of soybean cultivation, with possibility from decrease of costs and risks in the activity, increasing the competitiveness of the agrobusiness through the linear programming. The work presents a literature revision about the concepts of microeconomics cost, operational research and agricultural aviation. It intends a model of linear programming for choice the model of agricultural airplane of smaller cost; and makes sensibility analyses for the variables of the proposed model. The methodology used for the development of the model uses the referring data of the agricultural airplanes existent in the market among national and imported airplanes. The calculations are divided in two stages, one before the optimization and the especific optimization. The calculations made before the optimization become separated in four stages, which are: the calculation of the fixed and variable costs of each airplane model, the capacity of operational area of each model, the demanded operational rhythm and the number of necessary airplanes to the attendance of the demand. The result selected as airplane of smaller cost schedule the model AV8, with a hourly cost of US$ 323.14, with a capacity of operational area from 175,18 hectares per hour, being the cost for hectare of US$ 1.84. The result can be interesting for companies of agricultural aviation and also for producers of larger scale or group of associated producers.
