TL;DR: An optimisation model and a solution method for maintenance routing and scheduling at offshore wind farms are proposed that finds the optimal schedule for maintaining the turbines and the optimal routes for the crew transfer vessels to service the turbines along with the number of technicians required for each vessel.

TL;DR: A bi-objective optimisation using a compromise programming approach is proposed for installation scheduling of an offshore wind farm and the proposed metaheuristic approaches produce interesting results as the optimal solution for some cases is obtained.

TL;DR: Two mixed integer linear programming (MILP) models are established to configure the optimal port layout, where the shapes of subareas that need to be located in the port are rectangular with several possible dimensional configurations to select from and the shape of the port area can be treated as either a convex or a concave polygon.

TL;DR: In this article, a metodologia for auxilio no planejamento otimizado do plantio and colheita da cana-de-acucar is presented.
Abstract: O Brasil e hoje o maior produtor mundial de cana-de-acucar e de acucar. E o segundo colocado na producao de etanol, e tem conquistado o mercado externo com o uso de biocombustiveis. Assim, este pais possui grandes companhias sucroenergeticas e estas possuem complexos sistemas de gerenciamento, tanto na parte industrial como no campo. Tendo os gestores que recorrer a diversas ferramentas computacionais e matematicas para auxilio nos planejamentos e tomadas de decisoes. Neste contexto, o proposto trabalho apresenta uma metodologia para auxilio no planejamento otimizado do plantio e colheita da cana-de-acucar nas unidades agricolas que compoem as usinas. Para isto foi proposto um modelo de otimizacao linear inteira com a finalidade de determinar o periodo otimo de plantio e colheita da cana em cada talhao, de forma a maximizar a producao de cana-de-acucar. Os resultados computacionais obtidos sao apresentados e discutidos.
