Um modelo para a logística do abate do gado de corte

Abstract

RESUMONeste artigo é apresentado um modelo matemático linear em variáveis inteiras para auxiliar o produtor rural a determinar a solução mais rentável, escolhendo o melhor frigorífico, a melhor estrada e o melhor caminhão para realizar o transporte das cabeças de gado para o abate. O modelo proposto leva em consideração a capacidade dos frigoríficos e dos caminhões disponíveis, bem como as diferentes rotas para efetuar o transporte do gado. Nos testes realizados, o modelo proposto foi resolvido pela versão gratuita do software LINGO. Os resultados obtidos foram superiores ou iguais àqueles fornecidos pelo método manual de tomada de decisão empregado pelos técnicos da fazenda.Palavras-chave: Transporte, Manejo, Bem-estar animal, Otimização. ABSTRACTThis paper presents a linear mathematical model in integer variables to help the rural producer to determine the most profitable solution, by choosing the best slaughter plant, the best road and the best truck to carry the livestock for slaughtering. The model proposed takes into account the capacity of the slaughter plants and trucks available, as well as the different routes to transport the cattle. In the tests performed, the model was solved by the free version of LINGO. The results obtained were better than or equal to those provided by the manual decision-making method used by the farm technicians.

Live animal transportation and sustainable supply chain: a systematic literature review

“…As a way of exemplifying the animal handling procedures, Ribeiro et al (2018), in a qualitative study, evaluated the alternatives available to decide on the capacity of the slaughter plants (in terms of price), best route (or road), and better means of transport (truck) to propose a method to determine the logistics of selling and transporting livestock heads and to ensure a more profitable solution for the rural producer. The optimal answer was generated via a mathematical model based on the data provided by rural producers of Farm X (Mato Grosso do Sul, Brazil).…”

“…As also observed for the authors, the study can advance in several directions, for example in the realization of new computational tests on broader and more complex databases; a study of cattle shipment from multiple origins (i.e., farms) to multiple destinations; introduction of the multiple-journey truck alternative; inclusion of the possibility of multi-period sale (i.e., adding the decision as to when it is most advantageous for the farmer to carry out the sale to the slaughter plants); and introduction of the probability of greater losses to the cargo carried, such as truck breaks and accidents (Ribeiro et al, 2018).…”
