This paper develops a multistage stochastic programming to optimally solve the distribution problem of refined products. The stochastic model relies on a time series analysis, as well as on a scenario tree analysis, in order to effectively deal and represent uncertainty in oil price and demand. The ARIMA…

Computer Aided Chemical Engineering (Published)
Nov, 2017

Uncertainties arise from several sources and may introduce diverse risks within the oil supply chain (OSC), hindering its management, besides raising costs and lowering margins. The purpose of this work is to present a new stochastic approach to deal with different sources of uncertainty, by…
