1. Capacited Vehicle Routing Problem with CO2 Emission Minimization Considering Path Slopes
ABSTRACT This work presents the application of a CO2 emission estimation function for cargo vehicles on a Capacited Vehicle Routing Problems (CVRP) setting, considering route’s slopes variation. Comparisons were established with functions minimizing fuel consumption and route length in a case study about selective collection of recyclable waste at Sorocaba

2. Balanço de carbono em cidades da Amazônia: estudo de caso em Belém, Brasil
Resumo O município de Belém, no Pará, tem apresentado crescimento contínuo de sua área urbanizada e da frota de veículos nas últimas décadas. Essas mudanças estão também associadas a reduções na área de cobertura vegetal e ao aumento das emissões de CO2 locais. Há, portanto, a necessidade de se entender, de maneira integrada, a dinâmica das

3. QUALITY ANALYSIS FOR THE VRP SOLUTIONS USING COMPUTER VISION TECHNIQUES
ABSTRACT The Vehicle Routing Problem (VRP) is a classical problem, and when the number of customers is very large, the task of finding the optimal solution can be extremely complex. It is still necessary to find an effective way to evaluate the quality of solutions when there is no known optimal solution. This work presents a suggestion to analyze the qualit

4. MULTI-VEHICLE COVERING TOUR PROBLEM: BUILDING ROUTES FOR URBAN PATROLLING
ABSTRACT In this paper we study a particular aspect of the urban community policing: routine patrol route planning. We seek routes that guarantee visibility, as this has a sizable impact on the community perceived safety, allowing quick emergency responses and providing surveillance of selected sites (e.g., hospitals, schools). The planning is restricted to

5. Process capability index Cpk for monitoring the thermal performance in the distribution of refrigerated products
Abstract The temperature of refrigerated products along the cold chain must be kept within pre-defined limits to ensure adequate safety levels and high product quality. Because temperature largely influences microbial activities, the continuous monitoring of the time-temperature history over the distribution process usually allows for the adequate control of

6. Some experiments with a savings heuristic and a tabu search approach for the vehicle routing problem with multiple deliverymen
In this work we consider a variant of the vehicle routing problem that allows the assignment of multiple deliverymen to one or more routes. A practical motivation for this variant arises, for example, in the distribution of beverages in highly dense urban areas, characterized by the difficulty in serving daily requests within regular working day hours with a

7. Ação hepatoprotetora do antioxidante quercitina no modelo esperimental de esteato-hepatite não alcoólica
Introduction: Non-alcoholic steatohepatitis is a disease with a high incidence, difficult diagnosis, and yet no effective treatment. This reasons lead to the use of experimental models for induction of NASH, and the study of routes developing this disease, as well as attempts to a effective therapy. Aims: This study was designed to develop an experimental mo

8. Applied Logistic on routing and distribution of products in construction companies / Logística Aplicada à Roteirização e Distribuição de Produtos em Empresas de construção civil
The decision to search the routes in a particular construction company comes from the need to verify whether Vehicle Routing brought an effective optimization in the fleet, routes and delivery of cargo operations. Trip costs, distances and time were analyzed using TransCAD software, which gives a rich assemble of instruments for vehicle routing and solutions

9. Definição de rotas para coleta porta-a-porta de óleo residual de fritura visando o reuso / Definição de rotas para coleta porta-a-porta de óleo residual de fritura visando o reuso
The collection of solid waste generated in urban areas is a growing concern for governments, health professionals and environmentalists. Among these concerns is the disposal of vegetable oil used in homes, which requires a more appropriate final allocation. For this to be attained, it is necessary, in addition to public awareness, the planning for the collec

10. Image matching and classification for UAV navigation.
Unmanned aerial vehicles, known as UAVs, have evolved over the past two decades to sophisticated aircraft robots able to carry out surveillance, recognition, remote sensing and even attack missions. But there are not many alternatives of autonomous navigation systems for most of these aircraft which still require human intervention to navigate. Devices such

11. Estudo de durabilidade de rolamentos de roda baseado em rotas brasileiras / Durability study of wheel bearings, based on Brazilian route data
The present work has the objective of defining a load model to estimate the life of wheel bearing, suitable to the conditions of roads in Brazil. A comparative analysis of models of the routes currently available in the literature and practice was conducted and the effect of their loads on the bearing life was analised. A composition of loads extracted from

12. Uma abordagem heurística para o problema de roteamento de veículos com designação de entregadores extras / A heuristic approach for the vehicle routing problem with assignment of extra deliveries
The pursuit of excellence in customer service drives companies to investigate strategies that help to produce satisfactory solutions to the market, as is the case of beverage companies. One of the obstacles faced by this sector is the difficulty in distributing the demanded products within regular working hours due to long service times in each demand site.
