Logística externa de materiais : dificuldades em obras de construção em Angola

The objectives of this article are to analyze the role of external logistics in the construction sites in Angola and to evaluate the problems inherent in this activity in this country so we can find ways of increasing the rationalization of the production and, as a consequence of that, the competitiveness of Portuguese contractors operating in Angola. In spite of logistics being an administrative process that is incorporated, mainly, in the seriated industrial companies, it must also be applied to the construction industry because it presents unquestionable and vital benefits to its performance. Nevertheless, the evolution of logistics applied to the construction has been poor, which is proved by the limited bibliography in this area. This happens for two reasons: the intrinsic specificities of this industry and the consequent inapplicability of algorithms to rationalize production. Although it’s not viable to approach the logistics of construction through numeric models, it’s not unreasonable to study logistics applied to this area. Despite the fact that an approach to the construction logistics by numeric modeling is not viable, studying this theme continues to be meaningful. In most of the industries and especially in the construction one, the supply of resources (materials, equipments, workmanship or subcontractors) is an essential factor for the success of a business. The optimization of management of the supply chain for the construction industry constitutes one of the ways of optimizing a company and, especially, of increasing the profitability of its operations. Only through an improved logistic efficiency is it possible to take competitive advantage in the current market and, particularly, in the international market. In order for that to happen it is necessary to start making businessmen aware of the specific logistic difficulties in this industry and of ways to solve them either by disclosing them or by making businessmen reflect about them.

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.

A importância da regulação vigente para a obtenção de faixas horárias/Slots aeroportuários - caso de Portugal

Este trabalho discute a liberalização do transporte aéreo no mercado Europeu, o sucesso do tráfego aéreo, e a importância da regulação de slots aeroportuários para uma concorrência leal. Presentemente, dado o crescimento e a expectativa que o tráfego aéreo cresça ainda mais, os aeroportos e as companhias aéreas debatem-se com um problema de grande dimensão, que passa pela gestão aeroportuária de slots, uma vez que a capacidade dos aeroportos é limitada, e a procura por estas estruturas tem aumentado drasticamente. Face aos vários aeroportos Europeus, estima-se que essa capacidade seja atingida brevemente, fazendo com que a congestão não se dê só apenas por um curto período diário, mas que aumente não só a sua frequência como também a sua duração. Esta congestão pode ter efeitos sobre a concorrência entre as companhias e entre os aeroportos, o que implica que haja um impacto negativo, tanto no ambiente como na segurança. O estudo terá em atenção a capacidade do Aeroporto de Lisboa, ao pedido de slots aeroportuários, a legislação nacional e internacional, outros meios de afectação de slots aeroportuários, a posição da TAP relativamente à regulamentação existente, e aos meios paralelos.
