Integración de la red logística inversa y verde de las principales empresas proveedoras y clientes de la empresa Wong & Cía S.A

Ríos Paredes, Paola Elizabeth, Sánchez Dávila, Giuliana Rosa Angélica, Tello Pascual, Cintya Lisbet 01 January 2016 (has links)
En esta investigación se propone la implementación de un proceso logístico que involucre el cuidado del medio ambiente de manera efectiva. Actualmente, Wong & Cía. S.A presenta conciencia medio ambiental en sus políticas. Sin embargo, es importante que se consoliden algunas acciones dentro de la cadena logística para que la cadena verde que procede de las empresas extranjeras continúe también en la empresa. Asimismo, se busca integrar acciones que contribuyan a reducir el impacto de la contaminación ambiental en la cual contribuyan los clientes. Es por ello que en esta investigación se realiza un estudio en el que participan dos importantes proveedores y clientes para hacer efectiva la implementación de un área que integre la logística inversa y verde. / This research proposes the implementation of a logistic process that involves the care of the environment in an effective way. Actually, Wong & Cía. S.A presents an environmental awareness in its policies. However, it is important that some actions are consolidated within the logistics chain so that the green chain that comes from foreign companies continue also in the company. Likewise, it seeks to integrate actions that contribute to reduce the impact of environmental pollution, in which customers contribute. That is why in this research a study is made in which two important suppliers and customers participate to make effective the implementation of an area that integrates reverse and green logistics.

No. of bitstreams: 1 arquivototal.pdf: 3056611 bytes, checksum: e73001b52f3f37e092e742b4d599ce04 (MD5) Previous issue date: 2014-02-14 / Conselho Nacional de Desenvolvimento Científico e Tecnológico / This dissertation deals with the Pollution-Routing Problem (PRP), a Vehicle Routing Problem (VRP) with environmental considerations, recently introduced in the literature by Bekta ¸s e Laporte (2011). The objective is to minimize operational and environmental costs while respecting route-load constraints and service time windows. Costs are based on driver wages and fuel consumption, which depends on many factors, such as travel distance and vehicle load. Vehicle speeds are additional decision variables of the problem which complement routing decisions. They impact the total cost, the travel times between the locations, and thus the set of feasible routes. We propose a hybrid method that combines a local search-based metaheuristic with an exact approach and a recursive speed-optimization algorithm. Moreover, two other green VRP variants, the Fuel Consumption VRP (FCVRP) and the Energy Minimizing VRP (EMVRP), are addressed. The results obtained compare very favorably with those found in the literature, and many new improved solutions are reported. / Esta dissertação lida com o Pollution-Routing Problem (PRP), i.e. um Problema de Roteamento de Veículos (PRV) com considerações ambientais, recentemente introduzido na literatura por Bekta¸s e Laporte (2011). O objetivo consiste na minimização dos custos operacionais e ambientais, respeitando as restrições de carga dos veículos e janelas de tempo dos clientes. O custo é baseado no salário dos motoristas e no consumo de combustível, que depende de diversos fatores, como distância percorrida e carga transportada. As velocidades dos veículos são variáveis de decisão adicionais que complementam as decisões de roteamento. Tais velocidades interferem diretamente no custo total, nos tempos de viagem, bem como no conjunto de rotas viáveis. Uma abordagem híbrida que combina uma metaheurística baseada em busca local com uma abordagem exata e um algoritmo recursivo para otimizar as velocidades é proposta para solucionar o problema. Além do PRP, outras duas variantes do PRV com considerações ambientais são tratadas: o PRV considerando consumo de combustível e o PRV com minimização de energia. Os resultados obtidos se mostraram bastante favoráveis quando comparados com os melhores da literatura, e diversas soluções melhoradas são reportadas.

Logística e Sustentabilidade : Análise de casos de estudo e tendências

Fernandes, Maria Cristina da Silva January 2008 (has links)
In the last decades, the negative environment impacts of entreprise activities have gained wide recognition. Environmental issues affect numerous logistical decisions troughout the value chain. As concerns rises, companies must take more account of the external logistics cost related with the environment problems (such as climate change, pollution and scarcity of natural resources) and social problems (poverty, violence, unemployment...) Several studies suggest that green logistics strategies such as reducing consumption, recycling and reusing materials can bring large benefits. Companies should be able to create measures and strategies in order to achieve sustainable balance between economic, environmental and social objectives. This research intends to identify logistics-related environmental impacts in activities such as purchasing (raw materials acquisition), Transport, Warehousing/Distribution; to interpret concepts such as Green Logistics and Inverse Logistics; to present an international Case Study (Procter & Gamble) and a Portuguese Case Study (Unicer), showing the best practices employed by leading firms; finnaly, an overview of managers opinion about environmental and social problems, sustainable reports and environmental responsible logistics activities.

Atividades econômicas são geradoras de impactos ambientais resultante de suas operações, incluindo o setor das empresas de logística. Este tema tem atraído considerável atenção da comunidade científica internacional, entretanto, estudos sobre o tema no Brasil são incipientes. Nesta pesquisa foi realizada uma revisão estruturada da literatura que mapeou iniciativas verdes realizadas apenas por empresas Prestadoras de Serviços Logísticos (PSLs) e classificadas como internas e externas à organização em forma de um framework. Nesse contexto e de acordo com o estado-da-arte do campo de pesquisa apontado, o objetivo desta pesquisa foi de identificar iniciativas de sustentabilidade ambiental praticadas por algumas empresas PSLs brasileiras, e analisar a abrangência da realização das iniciativas. O método de pesquisa escolhido foi um estudo exploratório, com questionário semiestruturado, e coleta de dados do tipo survey. Com apoio do software NVivo10 foi possível entender as empresas estudadas, uma vez que facilitou as análises permitindo planejar e classificar informações oriundas de outras três questões abertas compostas no questionário, e pesquisar padrões nas respostas dos respondentes. Os resultados das análises indicam que as empresas respondentes têm realizado diversas ações a favor da sustentabilidade ambiental, entretanto algumas delas de forma pouco abrangente. A maior parte das iniciativas realizadas no contexto analisado são intraorganizacionais, quando comparada as interorganizacionais. / The pursuance for sustainability has been a topic debated among managers and academics around the world. Economic activities generate environmental impacts resulting from its operations, and also the logistics industry. This topic has attracted considerable attention from the international scientific community, however, studies on that issue in Brazil are incipient. The structured literature review mapped out green initiatives undertaken only by Logistics Service Providers (LSPs), and classified in the form of a framework as internal and external to the organization. In this context and according to the state-of-the-art of the research field pointed out, the aim of this research was to identify environmental sustainability initiatives practiced by some Brazilian LSP companies, and analyze the scope of the initiatives. The chosen research method was an exploratory study, with semi-structured questionnaire, and survey data collection. With the support of the NVivo10 software, it was possible to understand the companies studied, since it facilitated the analysis allowing to plan and classify information from three other open questions composed in the questionnaire, as well to search for patterns in respondents' answers. The results indicate that the surveyed companies have carried out several actions in favor of environmental sustainability, however some of them not with all potential. And most of the carried out initiatives are intraorganizational, when compared to the interorganizational ones. / CNPq: 134565/2015-0

It is a fundamental element for productive chains, as it unites markets by promoting the integration of regions and states. However, according to the report of Annual Estimates of Emissions of Greenhouse Gases for Brazil, launched in November 2015, the road modal, for using energy derived from oil, is considered the villain of CO2 emissions. Efforts to reduce emissions are made by business organizations, through the adoption of green logistics management (also known as environmental or ecological) to meet the precepts of environmental sustainability of the market, legal requirements, social responsibilities, Competitive in business. In this context, this paper aims to investigate the mediating role of environmental legislation in the relationship between green logistics management and logistic and environmental performance in the road freight transport sector of the Foz do Iguaçu - PR region. For that, a qualitative exploratory research was carried out with ten respondents from the transportation sector. The data collection was by accessibility, using a composite instrument in two parts: a) the first, referred to demographic data of the companies and of the respondents that were part of the sample and b) the second part referred to 14 open questions related to the research object. The data collected, from the first part were treated by the descriptive statistics and the data from the second part, corresponding to the open questions, were treated by the technique of content analysis. The data treated, evidenced the existence of positive relationships between the constructs (Green Logistics Management, Environmental Legislation and Environmental / Logistic Performance), thus being able to recognize the mediation of Environmental Legislation as a mediating variable in the relationship between green logistics management and environmental performance. Logistic. In view of this result, it can be concluded that environmental legislation plays an important role in the logistic performance and in the Green Logistics Management, and that these two performances can be achieved together and that no one is harmed by another. / No Brasil, segundo a Confederação Nacional do Transporte - CNT - o modal rodoviário representa 61% da matriz de transporte de cargas. É elemento fundamental para as cadeias produtivas, pois une mercados promovendo a integração de regiões e estados. Todavia, segundo o relatório de Estimativas Anuais da Emissão de Gases de Efeito Estufa para o Brasil, lançado em novembro de 2015, o modal rodoviário, por utilizar energia derivada de petróleo, é considerado o vilão das emissões de CO2. Esforços para a redução de sua emissão são envidados pelas organizações empresariais, por meio de adoção de gestão logística verde (também denominada de ambiental ou ecológica) eficiente para atender os preceitos da sustentabilidade ambiental do mercado, as exigências legais, responsabilidades sociais, e manter-se competitiva nos negócios. Nesse contexto, este trabalho objetiva investigar o papel mediador da legislação ambiental na relação entre gestão logística verde e desempenhos logístico e ambiental no setor de transporte rodoviário de cargas da região de Foz do Iguaçu, PR. Para tanto foi realizado uma pesquisa qualitativa exploratória junto a dez respondentes do setor de transporte. A coleta de dados foi por acessibilidade, utilizando-se de instrumento composto em duas partes: a) a primeira, referiu-se a dados demográficos das empresas e dos respondentes que fizeram parte da amostra e, b) a segunda parte, referiu-se a 14 questões abertas relacionados ao objeto da pesquisa. Os dados coletados, da primeira parte foram tratadas pela estatística descritiva e os da segunda parte, correspondentes às questões abertas, foram tratados pela técnica da análise de conteúdo. Os dados tratados, evidenciaram a existência das relações positivas entre os construtos (Gestão da Logística Verde, Legislação Ambiental e Desempenho Ambiental/Logístico), podendo assim reconhecer a mediação da Legislação ambiental como uma variável mediadora na relação entre gestão logística verde e desempenhos ambiental e logístico. Diante desse resultado pode-se concluir que a legislação ambiental possui um importante papel sobre os desempenhos logístico e na Gestão Logística Verde, e que esses dois desempenhos podem ser alcançados juntos, não ocorrendo o prejuízo de um em virtude de outro.

Relación entre la Logística Verde y las Exportaciones de Cobre de las minas ubicadas en la Macro Región Norte y Sur en el Perú en los periodos 2015-2019 / Relationship between Green Logistics and Copper Exports of mines located in the North and South Macro Region in Peru in the periods 2015-2019

Llanos Valentín, Marisol Alberta, Osorio Salvador, Ximena Alondra 01 October 2020 (has links)
El objetivo de la presente investigación es demostrar la relación entre logística verde y las exportaciones de cobre en las minas de la Macro Región Norte y Sur del Perú en el periodo 2015 al 2019. Cabe destacar que las empresas mineras exportadoras se encuentran ubicadas con mayor representación en la Región Norte y Sur del Perú. Así mismo, el cobre es el principal metal exportador, debido a que nuestro país logró conseguir presencia minera a nivel internacional, por la riqueza geológica que posee. Por tanto, es esencial identificar la relación entre las dos variables, para determinar si es recomendable la implementación de la logística verde en los procesos de las empresas mineras y si existe una influencia en las exportaciones. Para analizar la relación entre la logística verde y las exportaciones de cobre, se realizó una investigación cuantitativa, utilizando el cuestionario en escala de Likert dirigido a 32 personas pertenecientes a las áreas de comercio exterior, logística, operaciones, de las empresas mineras, las cuales representan el 80% del total de exportaciones en el periodo 2015 al 2019. Para realizar el análisis estadístico, se empleó el programa SPSS, con el fin de contrastar las hipótesis planteadas. De esta manera, se concluyó que la logística verde no se relaciona con las exportaciones de cobre durante el periodo analizado, siendo las dimensiones estudiadas; actividades logísticas, requerimientos ambientales y responsabilidad para definir la influencia de esta alternativa sostenible en las exportaciones. / The objective of this research is to demonstrate the relationship between green logistics and copper exports in the mines of the North and South Macro Region of Peru in the period 2015 to 2019. It should be noted that the exporting mining companies are located with greater representation in the North and South Region of Peru. Likewise, copper is the main export metal, because our country managed to achieve a mining presence at an international level, due to the geological wealth it has. Therefore, it is essential to identify the relationship between the two variables, to determine if the implementation of green logistics in the processes of mining companies is recommended and if there is an influence on exports. To analyze the relationship between green logistics and copper exports, a quantitative research was carried out, using the Likert scale questionnaire addressed to 32 people belonging to the areas of foreign trade, logistics, operations, of mining companies, which represent 80% of total exports in the period 2015 to 2019. To perform the statistical analysis, the SPSS program was used, in order to contrast the hypotheses raised. In this way, it was concluded that green logistics is not related to copper exports during the analyzed period, the dimensions being studied; logistics activities, environmental requirements and responsibility to define the influence of this sustainable alternative on exports. / Tesis

O método usado foi um estudo de caso único, sobre a sustentabilidade no transporte por cabotagem, focando seus impactos na emissão de CO2 na cadeia logística das operações da empresa no Brasil. Devido às dimensões continentais de nosso país, a cadeia logística é um grande desafio para atender às demandas de clientes com rapidez mantendo a sua competitividade e segurança. Dentro deste contexto a partir de 2015 a empresa intensificou o uso do transporte marítimo de cabotagem visando a redução de custos com seguros e evitar problemas com roubo de cargas. Porém uma externalidade positiva passou despercebida, que é a redução nas emissões de CO2 devido ao uso deste modal. Uma das metas em Sustentabilidade da empresa é minimizar o seu impacto climático, impedindo a liberação de 25 milhões de toneladas de dióxido de carbono e seus equivalentes (CO2e) ao longo de 15 anos, entre 2005 e 2020, e um dos caminhos é promover o uso de modais de transporte mais eficientes. Na revisão da literatura evidenciou-se que as emissões de CO2 por transporte rodoviário podem ser até 10 vezes maiores que o transporte marítimo para um mesmo volume de produto transportado (SCHMIED e KNÖRR, 2012). Portanto, esta pesquisa foi realizada através da análise exploratória sobre os dados dos embarques realizados pela empresa no período de janeiro/2015 a agosto/2018 e cálculo do impacto das emissões de CO2 dos respectivos embarques, adotandose o método proposto na norma CEN - EN 16258 – “Metodologia para o cálculo e declaração do consumo de energia e das emissões de gases com efeito de estufa dos serviços de transporte”. Esse trabalho visa contribuir para o estudo sobre sustentabilidade em cadeias logísticas e trazer maior clareza aos gestores sobre os impactos positivos à competitividade e ao meio ambiente ao adotar transportes alternativos ao tradicional rodoviário. / This work analyzes and propagates the sustainability of cabotage transport in the logistics operation of a home appliances manufacturing company. The research method was a case study, unique and holistic, about cabotage transport and its impacts on CO2 emissions in the logistics chain of the company's operations in Brazil. The continental dimensions of this country lead to a significant challenge in the logistics chain to meet the demands of customers, while quickly maintaining its competitiveness and safety. In this context, starting in 2015, the company intensified the use of cabotage shipping in order to reduce insurance costs and avoid problems with cargo theft. Nevertheless, a positive externality went unnoticed: the reduction in CO2 emissions due to the use of this modal. One of the company's sustainability goals is to minimize its climate impact by preventing the release of 25 million tonnes of carbon dioxide and its equivalents (CO2e) over 15 years between 2005 and 2020, and one way is to promote the use of more efficient transport modes. In the review of the literature, it has shown that CO2 emissions by road transport can be up to 10 times greater than maritime transport for the same volume of transported product (SCHMIED and KNÖRR, 2012). Therefore, this research was carried out through the exploratory analysis on the data of shipments made by the company from January/2015 to August/2018 and calculation of the impact on CO2 emissions of the respective shipments, adopting the method proposed in CEN- EN 16258 - "Methodology for calculating and reporting energy consumption and greenhouse gas emissions from transport services". This paper aims to contribute to the study on sustainability in logistics chains and to bring greater clarity to managers about the positive impacts in competitiveness and environment when adopting an alternative mode of transport to the traditional road transport.
