    Neste artigo apresentamos heurísticas usando o conceito da meta-heurística Busca Dispersa (BD), desenvolvidas para a solução do Problema de Roteamento de Veículos (PRV) Clássico, detalhando cada uma de suas etapas básicas quando aplicadas ao problema em questão. A Busca Dispersa é um método evolutivo que combina soluções com a finalidade de criar novas soluções de melhor qualidade; ainda que apresente similaridades com os algoritmos genéticos difere dos mesmos em princípios fundamentais. Um aspecto importante da BD é formar soluções com alta qualidade para dirigir a busca a regiões promissoras. Experimentos computacionais foram realizados em quatro conjuntos de dados disponíveis na literatura. Os resultados mostram que a BD é robusta e competitiva em termos de qualidade das soluções obtidas e tempo computacional para o PRV Clássico, para os conjuntos de dados testados.

    El ser humano es la razón principal de la existencia de residuos en el mundo. Los residuos sólidos peligrosos son aquellos que por sus características o manejo al que son o van a ser sometidos representan un riesgo significativo para la salud o el ambiente. El incentivo a la colecta selectiva y reciclaje de los residuos utilizados, trae beneficios a la sociedad en la economía de la energía, de los recursos naturales, generación de empleo entre otros. En el sentido de mejorar el aprovechamiento de los recursos naturales, la Logística Inversa proporciona el conocimiento de las formas de reintegración al mercado de los bienes beneficiados por los procesos de producción. Esta trabajo tiene como objetivo principal el de presentar a la Logística Inversa como una alternativa para identificar los principales puntos que caracterizan el impacto ambiental en la cadena productiva de algún producto; además que presentamos un estudio en la cadena productiva de petróleo y subsecuentemente considerar los ciclos productivos posibles de ser implementado por técnicas de Logística Inversa en la industria petrolera, en el producto de aceite lubricante. El estudio de caso se realizó en cuatro ciudades: Lima, Juliaca, Puno y Arequipa, donde se visitó distintas organizaciones, empresas, instituciones, municipalidades, gobierno regional y ministerios que están directamente relacionados con los derivados de petróleo. Se observó que las empresas generadoras de residuos no se responsabilizan por el destino final de los mismos, asimismo el marco legal existente no es conocido e incipiente. El ser humano, debe de entender el propósito de Dios en la creación hasta la actualidad, y mirando el futuro, sin olvidar que es parte de la creación de Dios y que tiene como deber reconciliar al resto de la creación con ÉL.

    Containers are fundamental elements for the development of international trade; however, it is estimated that there are more than 17 million retired containers stacked in ports around the world. Considering the high costs involved in the process of storing, transporting, or destroying these materials, in addition to their non-degradable nature, it is urgent to develop strategies for the sustainable use of these decommissioned containers. In this context, repurposing these containers into permanent structures is becoming a predominant trend. One solution is converting steel shipping structures into habitable spaces. However, due to the urgency with which Container Houses (CHs) are demanded in case of disasters, they are usually planned to be built as quickly as possible, serving as many people as possible, and do not consider the basic principles of energy efficiency. The performance of the CHs is, then, impaired, including risks of overheating, corrosion, and rust, among others, during service, making them an even more stressful experience for their users who are already in a vulnerable situation. Therefore, the objective of this study is to compare the performance of two thermal insulators applied to a temporary shelter container designed to promptly serve vulnerable populations. The model was developed in Building Information Modeling (BIM) software and simulated in Building Energy Simulation (BES) software, aiming to obtain subsidies for its technical and economic viability analysis. The results indicated that thermal insulators are able to generate significant savings in energy consumption, with mineral wool presenting better long-term performance.

    Tabu Search Applied to Community-based Rural Tourism
    (2017-01-01)

    Community-based Rural Tourism (CBRT) has been consolidated as a socially and environmentally responsible alternative in Peru for generating income opportunities for the rural sector. The development of CBRT is still incipient in Peru, and therefore the information generated by public and private institutions is insufficient and in some cases does non-exist. Worldwide, 91% of people use the Internet to find places to visit. However, the use of the Internet brings new challenges for the tourism industry. Different types of consumers, such as Baby Boomers, Generation X and Generation Y, present different challenges. Generation Y is the most active and much more involved in Internet travel planning. With regard to information on ecotourism and / or historic tourism in the Puno region of Peru, there is no information on the web, much less routes according to the needs of tourists. The objective of this work is to develop an Intelligent Digital Platform to apply data science and big data to find smart routes that satisfy tourists' requirements. To obtain the route, a nearest neighbor heuristic was implemented, using 2-opt and the Tabu Search metaheuristic implemented in Python programming language. Computational results demonstrate the efficiency of the Tabu Search algorithm when using data found in the literature and when using real data, guaranteeing the reduction of distances traveled in the shortest time possible, reducing travel costs.

    Though its origins can be traced back to 1977, the development and application of the metaheuristic Scatter Search (SS) has stayed dormant for 20 years. However, in the last 10 years, research interest has positioned SS as one of the recognizable methodologies within the umbrella of evolutionary search. This paper presents an application of SS to the problem of routing vehicles that are required both to deliver and pickup goods (VRPSDP). This specialized version of the vehicle routing problem is particularly relevant to organizations that are concerned with sustainable and environmentally-friendly business practices. In this work, the efficiency of SS is evaluated when applied to this problem. Computational results of the application to instances in the literature are presented.

    <p>Rural Community Tourism (RCT) is an activity that contributes to the economic, social and sustainable development of a country in rural areas. In this research, the goal is to develop an intelligent platform (IP) to meet the needs of different participants in RCT. It presents the experience of focusing on requirements engineering, going through different iterations where a SWOT analysis was performed, while using extreme programming, complying with ISO 25010, etc. The accurate identification of requirements is essential for the implementation and usability of the platform to have a social impact on the direct participants.</p>

    Urban drainage systems play an important role in the complex ecosystem of cities and are often subject to challenges that hinder their functioning. Although identifying these challenges is essential for developing policies and actions to improve drainage systems, there is a lack of studies addressing these challenges. This work has two objectives to contribute to filling this gap: (1) to research the main challenges that make it difficult to improve urban drainage systems; and (2) to prioritize them. We conducted extensive and detailed bibliographic research in which 15 challenges were identified, and a survey with 30 Brazilian professionals with experience in the concerned field. The results showed that 15 challenges identified in the literature were considered important by the survey respondents. It also showed that the most important challenges concern the inadequate functioning of drainage infrastructure, dynamics of city expansion, system maintenance, vulnerability of urban areas, public policies, and investments.
