SUPPLY CHAIN RESILIENCE ANALYSIS: A BRAZILIAN AUTOMOTIVE CASE

Supply chain (SC) resilience and flexibility are important research topics receiving growing attention. However, the academic literature needs empirical studies on SC resilience capable of investigating the inter-organizational components of flexibility along different tiers. Therefore, this paper analyzes the main lack of flexibilities in three Brazilian automotive SCs that limit their resilience and therefore their capacity to better support and meet the demand changes in the marketplace. A multi-tier case study approach is adopted. Research findings identify lack of flexibilities in different tiers that inhibit the SC resilience as well as manufacturing and SC flexibilities that build SC resilience. The findings also highlight that the same SC may have the flexibility to be resilient for one of its products but not for another product, what sheds new lights on the academic literature. Finally, flexible SCs should be designed to increase SC resilience to cope with mishaps as significant demand changes.

Concurrent Planning in the U.K.

O Planeamento Concomitante teve a sua origem no Reino Unido. É um método radical de intervenção social, baseado na Teoria de Afecto (Attachment Theory). O Planeamento Concomitante procura garantir que as crianças vulneráveis nas casas de acolhimento do Estado sejam adoptadas mais rapidamente possível. As crianças são acolhidas no âmbito deste Planeamento durante o período em que está em curso a avaliação da capacidade acolhedora dos pais adoptivos. As crianças sem condições de retorno para as suas famílias são desta forma legalmente adoptadas pelos pais adoptivos com quem as crianças já conseguiram desenvolver laços afectivos.

Contributo do enoturismo para o desenvolvimento de regiões do interior: o caso da rota dos vinhos do alentejo

The wine industry and its relationship with the tourism sector, as well as with the motivations, characteristics, and behaviors wine tourists are relevant for the valuable creation. Some scholars have identified distinct wine tourism market segments based on a supply-side analysis of certain wine-producing tourism destinations. Subsequent studies used cluster analysis to prove that specific wine tourism market segments can be identified in the Alentejo Wine Route. The significant dimension and economical importance of wine tourism in the Alentejo region point towards the need for more dynamic planning and branding efforts. Such efforts will no doubt place the Alentejo Wine Region on par with some of the foremost wine-producing regions in the world.

Scenario Planning and Evaluation of Pricing Strategies in the Portuguese Bulk LPG Market

Portugal has the largest LPG (Liquefied Petroleum Gas) share of primary energy demand in the EU (about 5%). Due to the increasing international cost of LPG in the last years and the high price sensitivity of the consumers the preference for substitute energy sources in new and existing consumers has been increasing. To select the kind of energy, some consumer estimate and compare the total costs while others follow agents (equipment sellers) recommendations. It takes time to build agents perception about the most advantageous source of energy, which is seen as an important resource that drives client resource accumulation and retention. Marketing strategies have to take into consideration some market dynamic effects derived from the accumulation and depletion of these resources. A simple system dynamics model was built, combined with Economic Value Added framework, to evaluate some pricing strategies under different scenarios of LPG international cost.

Enterprise Resource Planning governamental: a percepção dos servidores atuantes no Projeto Ciclo do Ministério da Justiça quanto à implementação

Indubitavelmente, a implementação de sistemas de gestão integrada é fator consolidado em empresas privadas; no entanto, em empresas públicas é relativamente recente e inovadora. Em 2009, o Ministério da Justiça (MJ) foi um dos pioneiros ao firmar parceria com a Universidade Federal do Rio Grande do Norte (UFRN) para a implantação de sistemas de gestão integrada. Com o decorrer dos processos de implementação surge a necessidade de identificar se o acordo surtiu os efeitos a que se destinou, bem como é pertinente a análise da implementação de um Enterprise Resource Planning (ERP) governamental em uma empresa pública, haja vista que existe uma tendência de que se repita em outras instituições governamentais. Assim, o principal objetivo deste artigo é identificar a percepção dos usuários quanto ao processo de implementação de sistemas integrados de gestão vinculados ao Projeto Ciclo, no âmbito da Secretaria Executiva do MJ, destacando suas principais dificuldades e benefícios. A fim de atingir o objetivo da pesquisa foi realizada uma pesquisa quali-quantitativa, cujo procedimento técnico foi o estudo de caso. Verificou-se que os usuários do sistema reconhecem sua importância como apoio à tomada de decisão, que estão cientes do papel que desempenham no processo de implementação e que a tecnologia da informação (TI) é fundamental para se obter melhoria nos processos executados. Ademais, percebe-se os avanços que um ERP governamental pode proporcionar a empresas públicas, destacando-se o planejamento e a confiabilidade das informações.

An appraisal of the health planning method proposed by the Pan-American Health Organization for Latin America

A brief description of the main features of the health planning technique developed by the "Centro de Estudios del Desarrollo" (CENDES) in Venezuela, and proposed by the Pan-American Health Organization for use in Latin America, is presented. This presentation is followed by an appraisal of the planning method which includes comments both upon its positive aspects and upon its negative points. Comments are also made referring to other recent publications of the WHO/PAHO on health planning. In conclusion, the CENDES technique is considered a health planning method of great potential for use especially in underdeveloped areas, the success of its application depending upon the hability of the health planners to introduce the necessary modifications to adapt to the local circunstamces.

Notes on health care planning in Latin America and the Caribbean

Attention is called to the fact that the efforts to improve health of populations in Latin America have generally failed. The inequality in the distribution of ill-health is great. The authors accept the fact that the lack of resources available to the health sector may be a restriction towards the improvement of the situation, but they argue that a much more important issue is the misuse of such resources and their maldistribution within the health sector. The lack of integration and coordination between the health services, the conflict of public and private health systems, the under-utilization of existing services and the gap between planning and real implementation are discussed.

The impact of improvement of water supply and sanitation facilities on diarrhea and intestinal parasites: a Brazilian experience with children in two low-income urban communities

During the second half of 1986 the impact of the improvement of water supply and excreta disposal facilities on diarrheal diseases and intestinal parasitosis was studied in 254 children up to six years of age from two favelas (shanty towns) of Belo Horizonte, Brazil. The estimated incidence of diarrhea was 6.2 episodes/child year and the estimated period prevalence reached 31.0 episode days/ child/ year. The point prevalence of parasitosis was 70.7% (Ascaris lumbricoides: 55.4%, Trichuris trichiura: 19.6%, Giardia lamblia: 17.9%). The estimated prevalence of diarrhea decreased with improvement of water supply and sanitation facilities to 45% and 44% respectively, but no statistically significant impact was observed in the case of parasitosis. School education and weaning practice were found to be other important determinants of diarrhea.

Limiting Internal Supply Voltage Spikes in DC-DC Converters

Implementing monolithic DC-DC converters for low power portable applications with a standard low voltage CMOS technology leads to lower production costs and higher reliability. Moreover, it allows miniaturization by the integration of two units in the same die: the power management unit that regulates the supply voltage for the second unit, a dedicated signal processor, that performs the functions required. This paper presents original techniques that limit spikes in the internal supply voltage on a monolithic DC-DC converter, extending the use of the same technology for both units. These spikes are mainly caused by fast current variations in the path connecting the external power supply to the internal pads of the converter power block. This path includes two parasitic inductances inbuilt in bond wires and in package pins. Although these parasitic inductances present relative low values when compared with the typical external inductances of DC-DC converters, their effects can not be neglected when switching high currents at high switching frequency. The associated overvoltage frequently causes destruction, reliability problems and/or control malfunction. Different spike reduction techniques are presented and compared. The proposed techniques were used in the design of the gate driver of a DC-DC converter included in a power management unit implemented in a standard 0.35 mu m CMOS technology.

Comportamento dinâmico da rede eléctrica da ilha de São Vicente em Cabo Verde: estabilidade de tensão

Neste trabalho é efectuado, não só o diagnóstico em regime permanente, mas também o estudo, simulação e análise do comportamento dinâmico da rede eléctrica da ilha de São Vicente em Cabo Verde. Os estudos de estabilidade transitória desempenham um importante papel, tanto no planeamento como na operação dos sistemas de potência. Tais estudos são realizados, em grande parte, através de simulação digital no domínio do tempo, utilizando integração numérica para resolver as equações não-lineares que modelam a dinâmica do sistema e dependem da existência de registos reais de perturbação (ex: osciloperturbografia). O objectivo do trabalho será também verificar a aplicabilidade dos requisitos técnicos que as unidades geradoras devem ter, no que concerne ao controlo de tensão, estabelecidos na futura regulamentação europeia desenvolvida pela ENTSO-E (European Network Transmission System Operator for Electricity). De entre os requisitos analisou-se a capacidade das máquinas existentes suportarem cavas de tensão decorrentes de curto-circuitos trifásicos simétricos, Fault Ride Through, no ponto de ligação à rede. Identificaram-se para o efeito os factores que influenciam a estabilidade desta rede, em regime perturbado nomeadamente: (i) duração do defeito, (ii) caracterização da carga, com e sem a presença do sistema de controlo de tensão (AVR) em unidades de geração síncronas. Na ausência de registos reais sobre o comportamento do sistema, conclui-se que este é sensível à elasticidade das cargas em particular do tipo potência constante, existindo risco de perda de estabilidade, neste caso, para defeitos superiores a 5ms sem AVR. A existência de AVR nesta rede afigura-se como indispensável para garantir estabilidade de tensão sendo contudo necessário proceder a uma correcta parametrização.

The role of European "ro-ro" port terminals in the automotive supply chain management

The aim of this paper is concerned with the design and development of a functional framework for maritime mode integration in European automotive supply chain management when considering outbound distribution. Furthermore, it provides a readjustment of traditional concepts and terminology with findings that the role of ro-ro port terminals should be considered as decoupling points, poles and postponement platforms. Case studies examine relevant Western European ro-ro port terminals for cars and respective links to assembly/factories of vehicles localized in the hinterland and concludes that ro-ro port terminals reduce logistical friction and impedance, as well as promote space/time compression.

Desenvolvimento de um plano de manutenção preventiva na rede de distribuição de água de Lisboa

O presente relatório de estágio enquadra-se no âmbito do trabalho final de Mestrado do curso de Engenharia Civil, área de especialização em Hidráulica, do Instituto Superior de Engenharia de Lisboa, e incide na temática dos sistemas de distribuição de água. O estágio decorreu na empresa EPAL – Empresa Portuguesa das Águas Livres, S.A., e teve como objecto o desenvolvimento de um plano de manutenção preventiva para a rede de distribuição de água de Lisboa. Devido à crescente complexidade dos sistemas de abastecimento de água e à grande dispersão territorial dos diversos órgãos integrados na rede, surge a necessidade de desenvolver um sistema que permita simplificar o planeamento e a gestão das intervenções de inspecção e manutenção preventiva dos órgãos. Para esse efeito, recorreu-se a um software SIG (Sistema de Informação Geográfica) para proceder à sectorização da rede de distribuição de água em pequenos grupos (Polígonos), constituídos por um número determinado de órgãos de manobra e segurança. Esta metodologia permite organizar as intervenções em pequenos grupos e optimizar as rotinas de Inspecção diárias. No decorrer do estágio efectuou-se ainda um levantamento dos procedimentos de inspecção e manutenção dos diversos órgãos integrados na rede de distribuição de água de Lisboa, quer por acompanhamento de actividades com as equipas de inspecção, quer por recolha de recomendações junto dos fabricantes dos órgãos. Este levantamento permitiu elaborar fichas de procedimento para as actividades de inspecção e manutenção preventiva dos diversos órgãos, afim de serem usadas como referência pelos trabalhadores.
