Opis:: Rail is the one of the highly underused form of freight transportation in the European Union. Majority of the freightage are distributed by trucks and HGVs. With new regulations and socio-environmental concerns urban logistics is facing a new challenge which can be tackled using innovative transport mechanisms and streamline operations. This article sheds light on a system which integrates freight distribution via metro lines in the closest vicinity of the customer, use of council warehouses and further innovative transport mechanisms for final delivery. This system uses existing infrastructure effectively without impacting its surroundings and triggers the reduction of polluting carriers. This system offers the option of immediate implementation which will enable EU to compete with a global freight distribution market.
O caminho-de-ferro e um dos meios de transporte de mercadorias mais subaproveitado na União Europeia. A maioria da carga transportada é distribuída recorrendo ao transporte rodoviário. A entrada em vigor de novos regulamentos em conjunto com o aumento das preocupações sociais e ambientais, levam a que logística urbana enfrente novos desafios. Desafios estes que podem ser superados através de mecanismos inovadores e ou pela otimização de processos. Este artigo propõe uma nova abordagem através de um sistema que integra o transporte urbano de mercadorias sobre a rede de metropolitano chegando assim mais perto do destino final da carga, propõe ainda a instalação de pequenos centros de distribuição local e formas inovadoras de transporte até ao destino final da mercadoria. Este sistema utiliza a infraestrutura já existente de forma eficiente e sem impactos para a sua vizinhança, contribuindo assim para a redução da poluição causada pelo transporte rodoviário. Este sistema oferece a possibilidade de implementação imediata o que contribuirá para que a União Europeia possa competir num mercado de transporte de mercadorias global.

Opis:: The problem of sequencing jobs on a single machine to minimize total cost (earliness and tardiness) is nowadays not just important due to traditional concerns but also due to its importance in the context of Collaborative Networked Organizations and Virtual Enterprises, where precision about promptly responses to customers’ requests, along with other important requirements, assume a crucial role. In order to provide a contribution in this direction, in this paper the authors contribute with an applied constructive heuristics that tries to find appropriate solutions for single machine scheduling problems under different processing times and due dates, and without preemption allowed. In this paper, two different approaches for single-machine scheduling problems, based on external and internal performance measures are applied to the problem and a comparative analysis is performed. Computational results are presented for the problem under Just-in-Time and agile conditions on which each job has a due date, and the objective is to minimize the sum of holding costs for jobs completed before their due date and tardiness costs for jobs completed after their due date. Additional computational tests were developed based on different customer and enterprise oriented performance criteria, although preference is given to customer-oriented measures, namely the total number of tardy jobs and the maximum tardiness.
