A review of mathematical optimization models applied to the sugarcane supply chain

Abstract

Sugarcane is a product of great economic relevance and, as well as its use for the production of different types of sugar, it is also a renewable source for the production of bio‐fuels, other bio‐products, and electricity. In this context, efficient planning and technology changes are necessary to ensure high productivity, competitiveness and harmony with economic, social, and environmental issues. Consequently, this sector needs technical and scientific support. Mathematical optimization models can be useful to build efficient planning tools for the activities involved in the sugarcane supply chain, helping to address these challenges. This paper describes the sugarcane supply chain and presents a literature review of mathematical optimization models that have been proposed to represent its main stages: planting, harvesting, transporting, industrial processing, and marketing. The findings show that several models have been proposed to represent these five stages, however, most of them have not been thoroughly explored from the point of view of strength of the models and solution methods. Moreover, the harvesting stage is the one that has received more attention than the other stages. In the integration of two or more stages, there are many challenges yet to be addressed by mathematical optimization models. This review contributes to a better understanding of the sugar‐energy sector and opens up new perspectives for future investigations.

Optimizing the Design and Planning of a Sugar-Bioethanol Supply Chain under Uncertain Market Conditions

“…Optimization models based on mathematical programming have been used to study the sugar cane supply chain by way of modeling its main stages in order to improve its overall management. 15 To provide an overview of the existing body of knowledge, Table 1 gathers 17 academic works that have been proposed from 2009 to 2021 to study the sugar cane supply chain network from a strategic-tactical planning perspective.…”

Biofuels technologies: An overview of feedstocks, processes, and technologies

“…Estos artículos tienen una particularidad y es que son los únicos que involucran desempeño de los cultivos de caña de azúcar como variable que depende de las socas y la edad del cultivo; también, se incluye el ciclo de vida del cultivo desde la siembra y sus múltiples cortes. Adicionalmente, en la revisión sistemática realizada por Teixeira et al (2021) se identifican solo tres artículos en los últimos 10 años en los cuales se involucran las actividades de siembra y cosecha (Carvajal et al, 2019;Florentino et al, 2020;Poltroniere et al, 2021).…”
