Optimal design and planning of biodiesel supply chain with land competition

Abstract

In this work we propose an MILP multiperiod formulation for the optimal design and planning of the Argentinean biodiesel supply chain, considering land competition and alternative raw materials. The country is divided into twenty three regions, each one including existing crops, oil and biodiesel plants and potential ones. The model includes intermediate and final products, i.e., seed, flour, pellets and expellers, oil, pure and blending biodiesel and glycerol. Crop fields, storage and production plants, as well as distribution centers for internal and external markets are also represented. We consider the possibility of sowing energetic crops, such as Jatropha curcas, in marginal areas. The time horizon is of seven years, divided into 84 periods. The mathematical model has been implemented in GAMS providing a powerful decision-making tool that can be applied to other regions or countries by adjusting specific data.

Pareto-efficient legal regulation of the (bio)fuel market using a bi-objective optimization model

“…Bai, Hwang, Kang, & Ouyang, 2011) or integrate it as a constraint (e.g. Akgul, Zamboni, Bezzo, Shah, & Papageorgiou, 2011;Andersen, Iturmendi, Espinosa, & Diaz, 2012;Zamboni, Shah, & Bezzo, 2009). However, this does not allow accounting for unintended side effects of political regulations as the available biomass is being restricted right from the start.…”

Biomass to Energy Supply Chain Network Design: An Overview of Models, Solution Approaches and Applications

“…They used their model to construct a biomass to ethanol supply chain in a region with nine states in Midwestern USA. Andersen et al (2012) proposed a multiperiod MILP model for the optimal design and planning of biodiesel supply chain representing all components of the supply chain such as crop fields, storages, production plants and distribution centers. The model also considers crop land competition and alternative feedstocks.…”

“…Many authors have formulated optimization problems similar to those proposed in this study adopting an economic viewpoint [12], defining prices and costs of any agricultural plans. The first is as important as it is controversial.…”
