Abstract:ResumoEsse trabalho aborda um problema de planejamento da produção típico de empresas moveleiras de pequeno porte, em que as demandas e os tempos de preparação dos estágios gargalos são variáveis aleatórias que podem ser aproximadas por um conjunto discreto e finito de cenários ponderados pelas correspondentes probabilidades de ocorrência. O problema com múltiplos cenários é modelado via programação estocástica de dois estágios com recurso. Para controlar a variabilidade dos custos de segundo estágio é propost… Show more
“…The treatment of uncertainty in models has become increasingly relevant. The authors in [18,19] approach stochastic modeling techniques to treat the production process in industries considering real contexts. The objective of both works is to represent the reality of the plant considering possible unforeseen events that may actually happen in the real world.…”
A scientific challenge on industrial production is to mathematically represent a production process, and this challenge increases when describing production processes with stochastic behavior. The present paper will be approaching a specific part of the production process of soybean oil, where the main objective is to maximize the oil extraction by keeping the thicknesses of the soybean flakes within an operating range. We propose a method, based on a mathematical stochastic model, to obtain pressure setpoints that produce flakes as ideal as possible for oil extraction. The results reported are achieved by applying the proposed method in the industry with improvements within the process in terms of time and quality.
