Article 0 Reads 0 Citations Corporate sustainability assessment heuristics: A study of large Brazilian companies Published: 01 July 2018
Journal of Cleaner Production, doi: 10.1016/j.jclepro.2018.02.232
This study proposes a heuristic for assessment of corporate sustainability based on the Corporate Sustainability Index (ISE) of the B3 (former BM&FBovespa) in Brazil. The survey was conducted in three phases: (i) experts identified sustainability dimensions and measurement methods; (ii) the ISE criteria were classified as mandatory or compensatory and (iii) two assessment approaches were compared: (a) Evaluation of Weighted Sum (WS), which uses simple weighted average, and (b) the proposed evaluation approach, based on the Minimum Performance on Mandatory Items (MPMI), which focuses on the deficits of the dimensions and criteria of corporate sustainability. Sixty organizational units were evaluated and compared using WS and MPMI approaches. The proposed MPMI clarifies that, in the pursuit of corporate sustainability, higher performance in some dimensions may not be enough, and instead, it is necessary to comply with all dimensions. Besides, when compared to the traditional weighted approach, MPMI provides a more transparent assessment of corporate sustainability through a clear identification of the criteria and dimensions to be improved.

Journal of Cleaner Production, doi: 10.1016/j.jclepro.2018.03.272
Recent research suggests that environmental benefits can be attained by changing the behavior of users and how they interact with products. The recognition that users play a fundamental role in generating more (or less) environmental impact during product usage has led to studies on design and how it can be used to influence user behavior. In this scenario, approaches and tools that explicitly focus on Design for Sustainable Behavior began to be developed. Conceptually, Design for Sustainable Behavior focuses on products and how these can be designed for users to behave more sustainably during their use. Different frameworks containing behavior changing strategies have been proposed in the literature. Based on the perception of twelve experts, this paper assesses these frameworks and identifies similarities and complementarities, aiming to unify vocabulary and methodologies to avoid unnecessary uncertainty and confusion. It also proposes a decision support diagram that relates the main contributions identified by the experts in the frameworks and adds questions to help designers define control. The diagram contains four phases: (i) user analysis; (ii) level of user or product control; (iii) strategy definition; and (iv) means to incorporate strategies to the product. Furthermore, considering the need to determine the usability of the proposed diagram, its use in practical cases within companies was assessed. In terms of future research, additional studies are suggested to confirm the relationships established between generic strategies (inform, guide, and ensure the change) and the specific strategies.
Article 0 Reads 0 Citations Proposal of a novel reference system for the green product development process (GPDP) Published: 01 June 2018
Journal of Cleaner Production, doi: 10.1016/j.jclepro.2018.03.237
This study aimed to investigate the alignment between environmental sustainability and the product development process of Small and Medium-sized Enterprises that operate in Southern Brazil, as well as to propose a system to assist the execution of a green product development process. To that end, an exploratory research was carried out in two steps: (i) narrative bibliographic review and (ii) a field research. The (i) bibliographic review was conducted in the “Web of Science” and “Scopus” databases. The (ii) field research was executed with managers of 18 industries of different segments. Regarding the theoretical research, results show the state-of-the-art in academic research on product development process and sustainability practices, which provided support for the design of the data collection instrument and for the reference system suggested at the end of the work. As to the field research, results show that the sampled organizations understand the need for product and process environmental sustainability and they define internal drivers for the adoption of adequate practices, adapting such practices to the regulatory pressures and to market demands. Nevertheless, environmental matters do not comprise a dominant topic on product development. In this sense, we propose a reference model that aims to support companies to strategically align environmental aspects to the product development process. Although literature describes specific reference models, the need for a new system is justified since previous models presented specificities, lacked both post development assessment phases and introductory phases of product planning before the conceptual design. Therefore, the reference system proposed present phases that precede the development process (Sustainability-Oriented Organizational Strategic Planning; Portfolio Strategic Planning; and Project Strategic Planning), followed by the development phases (Operational Planning of the Product; Production Preparation; and Product’s Launch Plan), and one post-development phase (Market Follow-Up of the Product). Future studies can apply the model in real cases through the action research method.
Article 1 Read 1 Citation Optimal Time Interval Between Periodic Inspections for a Two-Component Cold Standby Multistate System Published: 01 June 2017
IEEE Transactions on Reliability, doi: 10.1109/TR.2017.2689501
The establishment of the optimal time interval between inspections for multistate redundant systems considering availability and costs related to maintenance and production losses is a challenging issue. This paper extends previous research for redundant multistate systems where the time-to-repair cannot be neglected. Discrete-time Markov chains are used to define transition probabilities between the different system states and the costs related to each transition. To optimize the time interval between inspections, the total cost is minimized utilizing the Markov chains properties followed by a numerical search technique. Two models are analyzed and numerical examples are presented. System I is a binary system with cold standby redundancy and component repair, while system II is a multistate system with cold standby redundancy and component repair. The main contribution of the method presented in this paper is the establishment of the optimal time interval between inspections for cold standby systems comprised of components that have different levels of degradation and where the component state can be determined only through periodic inspections. Systems with these characteristics are widely applied in industry, but are still not fully modeled in the literature.

Article 2 Reads 4 Citations Worker evaluation of a macroergonomic intervention in a Brazilian footwear company Published: 01 July 2014
Applied Ergonomics, doi: 10.1016/j.apergo.2013.11.007
This article presents a macroergonomic intervention in a Brazilian footwear company and its evaluation by the workers. Using participatory ergonomics, the traditional Taylor/Ford production system was transformed into a socio-technical one and tested by 100 volunteers working during 3.5 years in a pilot production line. Multiskilling and teamwork were the major changes promoted to enlarge and enrich work and make it more flexible. The workers' evaluation pre- and post-intervention showed an increase in overall satisfaction with the work and more commitment to the results and company targets.
