Abstract
The problem of selecting suppliers/partners is a crucial and important part in the process of decision making for companies that intend to perform competitively in their area of activity. The selection of supplier/partner is a time and resource-consuming task that involves data collection and a careful analysis of the factors that can positively or negatively influence the choice. Nevertheless it is a critical process that affects significantly the operational performance of each company. In this work, trough the literature review, there were identified five broad suppliers selection criteria: Quality, Financial, Synergies, Cost, and Production System. Within these criteria, it was also included five sub-criteria. Thereafter, a survey was elaborated and companies were contacted in order to answer which factors have more relevance in their decisions to choose the suppliers. Interpreted the results and processed the data, it was adopted a model of linear weighting to reflect the importance of each factor. The model has a hierarchical structure and can be applied with the Analytic Hierarchy Process (AHP) method or Simple Multi-Attribute Rating Technique (SMART). The result of the research undertaken by the authors is a reference model that represents a decision making support for the suppliers/partners selection process.

Abstract
This project aimed to analyze the practical difficulties in storing and moving a high range of products making the process easier and more efficient. The objectives were to improve the use of available space in the raw materials warehouse and ensure the effectiveness, efficiency and reduction of the periods between the transportation from raw materials to production lines. The work developed focused on improving internal processes, storage practices and internal transportation. In fact, for the production flow to be continuous, the supply must be aligned with the production to ensure that there is no failure of materials.

Revolução industrial 4.0 e desenvolvimento de competências: Avaliação do Projeto Universidades do Futuro

Abstract
A realidade com a qual lidamos atualmente é absolutamente desafiadora no que diz respeito aos nossos paradigmas de resolução de problemas mais conservadores. Os avanços tecnológicos, as transformações sociais, bem como os perfis dos atuais líderes (nas empresas ou nas instituições públicas) destas primeiras décadas do milénio, implicam que os gestores e futuros executivos estejam adequadamente preparados para responder com sucesso a esta Nova Era em que a Revolução Industrial 4.0 (I4.0), se está desenvolvendo. Conscientes desses enormes desafios, foi desenvolvido um projeto internacional durante cerca de três anos com diferentes propostas educativas e que agora se apresentam, avaliam e exigem a nossa reflexão. Procurando responder às múltiplas solicitações que os empregadores reclamam repetidamente sobre o gap que existe entre as competências desenvolvidas na Academia e as que são necessárias no Contexto Industrial, o projeto Universities of the future - UoF, procurou diminuir o fosso entre estas duas realidades através de uma oferta formativa diferente, (co)construída entre equipas representantes de diferentes contextos para um melhor perfil de competências dos “executivos/as 4.0”.

Abstract
Occupational safety is a major concern these days because it is an important social issue promoting financial implications for organisations, employees, and society. But while occupational safety is an important concern, the top management of organizations usually prioritize waste and cost reduction. Therefore, there is a need for a technique that reduces waste and simultaneously improves occupational safety. Lean has been effective in reducing waste and costs. Some researchers have shown that Lean can also improve occupational safety. The objective of this work was to determine wether, in organizations where Lean tools were implemented, if there was an improvement in occupational safety conditions, namely in the reduction of accident rates, and to verify which Lean tools contributed the most to that improvement. A survey was conducted by sending a questionnaire to Portuguese organizations, from north to south and islands, who had potentially Lean tools implemented. In total, 189 answers have been obtained from organizations, 59 of which had Lean tools implemented, being considered valid answers for the study. Through statistical analysis of the data obtained, it was found that no organisations had worsened their safety indicators, some had maintained the same level and a reasonable number stated that their indicators had improved. Of these, the vast majority said that their accident rates had decreased by 20%, this being the figure that statistically showed the best results in terms of change.
