Environmental performance of freight trip generation hubs

A freight trip generation hubs has a large potential of environmental impacts caused, also, by transportation operation. Thus, it is necessary a method of performance assessment capable of identifying and evaluating the environmental impacts in order to monitor the performance over time and develop improvement actions. Therefore, this paper aims to propose an environmental performance assessment method of freight trip generation hubs. Documental and bibliographic researches were done in order to get this purpose and we get a structured method, consisted for 8 steps.

Improving post-sale reverse logistics in department stores: a Brazilian case study

Post-sale reverse logistics has grown in importance in the supply chain. As a contribution to scientific innovation, we present a structured procedure for reverse supply chain management of goods after sale. In addition, a comparison is made between the structures of direct supply chains by checking the similarity in terms of transport operations, inventory management and information management, which allows its application in the case study. This paper aims to suggest a procedure to structure the reverse logistics chain which is based on Process Management and consider three basic levels: Product Entry Management, Resource Management and Performance Management in the Reverse Logistics Chain. A bibliographical and documentary review was conducted in addition to a field research with a group of three department stores. The data collected from the companies using questionnaires and interview shows that the application of the procedure suggests that a better structuring of management in post-sales reverse logistics in the retail market can improve financial results in companies by contributing to reduce product returns and consequently its costs, improve efficiency in inventory and storage management, improve assets usage, increase revenue and promote social benefits such as donation of the products which was used and had been returned for charity.

Evaluation of Best Practices Introduction for the Managerial Improvement in Urban Freight Transport

Abstract The last mile of parcel deliveries is a key process to service providers, with global costs that reach up to 70 billion euros per year. Moreover, due to urban population growth and to the rise of e-commerce, the importance of last-mile deliveries and its impacts to the environment and quality of life in cities tend to increase even more. This chapter proposes a more comprehensive methodology to assess alternative last-mile distribution strategies in terms of environmental and economic aspects and presents an application to the distribution of a postal company located in the city of Rio de Janeiro, Brazil. We evaluated the use of small electric vehicles (i.e., tricycles) in the last mile deliveries by assessing two scenarios: (1) the baseline scenario using a light commercial vehicle and (2) a scenario using electric tricycles. Results indicated that the use of electric tricycle is a more feasible alternative regarding the economic and environmental aspects as well as to maintain the service level of the company.

O transporte na cadeia logística da indústria cimenteira

O consumo de cimento no Brasil cresce de ano a ano, chegando em 2012 no patamar de 69 milhoes de toneladas. Sendo um produto perecivel e de baixo valor agregado, o transporte e considerado um fator estrategico para a manutencao da competitividade e do mercado neste setor. Diante disso, este trabalho tem como objetivo descrever o modelo da rede de transporte da industria cimenteira e utilizando como exemplo um estudo de caso da cimenteira Lafarge no estado do Rio de Janeiro. O artigo mostra que no Brasil, embora a industria do cimento movimente grandes volumes de insumo e produtos acabados, sua cadeia logistica depende exclusivamente do transporte rodoviario, destacando uma infraestrutura logistica deficiente que nao se encaixa no modelo ideal onde o uso de modos de maior capacidade, como ferroviario e o maritimo de cabotagem deveriam apresentar participacao. Esta situacao faz com que a eficiencia neste setor dependa de solucoes criativas que venham de forma a integrar as decisoes estrategicas da companhia.

Improving the environmental performance of trip generators: case study Sepetiba Tecon terminal

This article aims to identify how measures that promote sustainability in freight transportation can affect the environmental performance of a load trip generator. To achieve this goal the method proposed by Guimaraes and Leal Jr (2013) was applied in the evaluation of Sepetiba Tecon Terminal, which is part of the Port of Itaguai. Economic and environmental aspects were evaluated considering some attributes, such as value of service that refers to the service produced and environmental influence that refers to energy consumption, emission of greenhouse gases, air pollution, water pollution and ground water consumption and material consumption. Were considered road vehicles and cargo handling equipment to estimate the emission of Greenhouse Gases (GHG) and air pollutants related to port activity. It was also performed a sensitivity analysis. This analysis had the intention to assess changes that may occur due to the difference in the weights assigned to each indicator used in the analysis and see how this variation changes the outcome.
