Enterprises' internationalisation strategy: skills in exportation and customs law

Economical development has always been connected to the commercial exchanges between people, due to the necessity to suppress their needs. With the increasing growth of international business and more competitive and demanding markets, exportation has become an important first step to internationalisation. Unlike what happened in the past, companies must be aware that the enrolment in the current global market is risky and requires elaborated technical procedures. Internationalisation should not be treated as an isolated event of business management. The first part of this paper aims to understand the export process and fit it in the current stage of international trade, keeping in mind the framework of export under the customs law. Then, we tried to understand how Portuguese companies should face this process in their internationalisation strategy, and what skills organisations must acquire to be able to export competitively in the current scenario of globalisation. The investigation was based on interviews in companies that, through a process of internationalisation by exportation, have implemented themselves strongly in extern markets. This investigation allowed us to analyse the companies’ motivations to become international, as well as the selection criteria for the export destinations. It was also possible to identify the main obstacles to the internationalisation of Portuguese companies. We concluded that companies that choose exportation as a way to become international acquire specific skills that enable them to become competitive in international trade. However, studies have failed to answer the second initial question about whether the measures implemented by Customs potentiate exports.

Shannon information and power law analysis of the chromosome code

This paper studies the information content of the chromosomes of twenty-three species. Several statistics considering different number of bases for alphabet character encoding are derived. Based on the resulting histograms, word delimiters and character relative frequencies are identified. The knowledge of this data allows moving along each chromosome while evaluating the flow of characters and words. The resulting flux of information is captured by means of Shannon entropy. The results are explored in the perspective of power law relationships allowing a quantitative evaluation of the DNA of the species.

Sectors and routes in solid waste collection

Collecting and transporting solid waste is a constant problem for municipalities and populations in general. Waste management should take into account the preservation of the environment and the reduction of costs. The goal with this paper is to address a real-life solid waste problem. The case reveals some general and specific characteristics which are not rare, but are not widely addressed in the literature. Furthermore, new methods and models to deal with sectorization and routing are introduced, which can be extended to other applications. Sectorization and routing are tackled following a two-phase approach. In the first phase, a new method is described for sectorization based on electromagnetism and Coulomb’s Law. The second phase addresses the routing problems in each sector. The paper addresses not only territorial division, but also the frequency with which waste is collected, which is a critical issue in these types of applications. Special characteristics related to the number and type of deposition points were also a motivation for this work. A new model for a Mixed Capacitated Arc Routing Problem with Limited Multi-Landfills is proposed and tested in real instances. The computational results achieved confirm the effectiveness of the entire approach.

Reengenharia do processo de reclamações das lojas

Num contexto global de incerteza, as cadeias de abastecimento mais ágeis e os clientes com mais exigências manifestam uma constante preocupação com a melhoria contínua da eficiência das operações logísticas. O presente projeto foi desenvolvido na empresa Sonae Modelo Continente Hipermercados, S.A, uma das duas principais empresas do retalho da grande distribuição alimentar em Portugal. Sendo a logística um fator chave de sucesso, uma das atividades críticas de uma empresa, é identificada a oportunidade de melhoria operacional do processo de negócio, a partir das reclamações dos clientes internos. O tratamento destas reclamações, incidências, é de grande complexidade e responsabilidade para a área do Logistics Customer Service. O projeto desenvolvido, a ‘Reengenharia do processo de reclamações das Lojas’, surgiu da necessidade de criar um modelo e processo de negócio de melhoria contínua, que solucione falhas operacionais com implicação na Logística, Supply Chain e em outras áreas da empresa. A procura dessa melhoria é o objetivo deste trabalho. Pretende-se, com a proposta aqui apresentada, a interligação e automatização da cadeia abastecimento, para superar as ocorrências operacionais, elevar a qualidade do serviço, aumentar a capacidade do processo e incorporar uma monitorização das atividades de input (Lojas) e output (Entrepostos), para futura rastreabilidade das operações, através da integração da cadeia de abastecimento, para a satisfação do cliente interno. Para a elaboração do novo modelo de processo foi seguida a orientação da reengenharia de processos de negócio, nas suas linhas orientadoras: identificação do modelo de processo atual e das suas necessidades; definição dos objetivos norteadores do projeto a apresentar; redesenhar novo modelo de processo de negócio, de modo a dar resposta às necessidades detetadas nos clientes internos.
