Abstract
Raw materials are very important for the development of economies and also to assure quality of life. Due to our production and consumption patterns new challenges emerged. The consumption of raw materials is very high, what raises important issues such as the depletion of resources, instability of prices and markets, risk of rupture of supply and other environmental, economic and social impacts. The European Union as many other regions of the world are implementing some strategies to overcome this problem, being the most recent the circular economy package, which intends to maintain materials as long as possible in the economic cycle, avoiding the use of new resources. There is a list of critical raw materials for EU and in this work the methodology of pairwise comparison was applied to a set of those raw materials for determining the importance of each taking in consideration several factors, such import reliance, end of life, economic importance, etc. The main goal was to develop a method based on pairwise comparison in a case of European Union to define priorities for acting, enhancing the achievement of sustainable solutions. It was also performed a sensitivity analysis. It was possible to conclude that the top position for the majority of the several raw materials does not change with the weights. Tantalum, Tungsten, Baryte and Antimony are always in the top positions. (C) 2019 The Authors. Published by Elsevier B.V.

Abstract
Nowadays, Lean Manufacturing, Industry 4.0, and Sustainability are important concerns for the companies and in a general way for the society, principally, the influence of the two production philosophies, Lean Manufacturing and Industry 4.0, in the three main pillars of sustainability: economic, environmental, and social. According to the literature review done in this work, these relations are not well known and are dispersed by different sustainability's criteria. To address this gap, this research proposes a structural equation model, with six hypotheses, to quantitatively measure the effects of Lean Manufacturing and Industry 4.0, in Sustainability. To statistically validate such hypotheses, we collected 252 valid questionnaires from industrial companies of Iberian Peninsula (Portugal and Spain). Results show that: (1) it is not conclusive that Lean Manufacturing is correlated with any of the sustainability pillars; and (2) Industry 4.0 shows a strong correlation with the three sustainability pillars. These results can contribute as an important decision support for the industrial companies and its stakeholders, even because not all the results are in line with other opinions and studies.

Abstract
This research evaluates IRCA registered auditors' perspectives of the added value of ISO 9001:2015 to the organizations that adopt it and are certified accordingly, bringing P a more independent perspective than previous studies based on quality managers or consultants' views. Supported by a worldwide survey among IRCA registered auditors and the adoption of a Covariance based- Structural Equation Modelling (CB-SEM) approach the results point out that the auditors' judgment regarding the ISO 9001:2015 value is influenced by their perceptions (regarding the document) and experience (auditing). The research results highlight the importance of selecting auditors with the appropriate ISO 9001:2015 knowledge and experience to assess ISO 9001:2015 Quality Management Systems (QMSs) within the certification process, therefore, contributing to the business and processes performance improvement and sustainable outcomes.

Abstract
Value analysis methodology uses a structured and methodical job plan contemplating several steps to ensure success in its application. This paper intends to perspective the potential of value analysis application, namely in the furniture industry. To draw conclusions of this potential a case study was developed at an IKEA factory in Portugal. To characterize the customer needs in a clear language and to quantify the value of a product (a bookcase) produced in this factory, a value analysis study was developed. Functional analysis is the most known and distinctive phase of value analysis and is, nowadays, an autonomous tool. With this functional analysis, the authors intend to describe the functions that the product performs, to provide a better knowledge of the product, to evaluate the degree of satisfaction of the product through its functional performance and to facilitate the search for alternative solutions. The results obtained allowed us to reach some important conclusions about the application of value analysis in this type of industry and can be an initial step I to promote the use of this tool in this kind of industry.

Abstract
In a more and more competitive and industrialized market, it is essential that companies realize that the way forward must go through the optimization of their production processes, reducing the costs and increasing product quality. Nowadays it's necessary to adopt innovative management models that can provide increased productivity at minimal costs, such as the Lean thinking. The metalworking industry is integrated into one of the most competitive existing markets in Portugal. Given this, it's fundamental to reduce the waste in all sectors of the production process, using the good Lean principles and practices, such as the Single Minute Exchange of Die, also known as SMED methodology. This paper presents a project of implementing the SMED methodology in the cold profiling process, in a population of five different profiling machines. The results of the SMED implementation show an average OEE improvement of 10,8%.
