“…Thus, the VFT methodology will be applied in this study to extract the objectives, and then to obtain the criteria that represent the desires/objectives of the DM. The application of the VFT in this research is based on an adaptation of the procedure proposed by Alencar et al (2011), according to the following steps: a. Identification of values: A semi-structured questionnaire based on the techniques proposed by (Keeney, 1996) was applied to the DM.…”

Paper aims: This paper proposes a multicriteria decision approach for supplier selection using a multicriteria method based on Flexible and Interactive Tradeoff (FITradeoff) elicitation process, within the ranking problematic perspective. Originality: This paper develops a framework integrating the results of VFT (Value-Focused Thinking) method with the Triple Bottom Line (TBL) dimension and the veto concept to improve the decision process within a multicriteria perspective. Research method: This study provides a case study in a textile company in Campina Grande, northeast Brazil using data mainly from semi-structured interviews. It also employs quantitative techniques based on problem structuring methods and multicriteria decision making. Main findings: The VFT helped in identifying criteria that are not yet explored by the company, and in structuring the decision problem of how incorporate and balance the TBL dimensions. The recommendation obtained by using the proposed multicriteria decision framework is different from the group of suppliers currently used by the company. Implications for theory and practice: Clarify and identify different objectives and to specify the consequences of a decision problem, allowing the Decision Maker (DM) to obtain and prioritize an economic and sustainable solution for a given number of suppliers to be selected, saving his time and effort.

A Sustainable Approach to the Governance of Waste Management

The European Union's revised Waste Framework Directive 2008/98/EC gives priority to waste prevention in its hierarchy of waste management measures. This paper argues that, to this end, the importance of costing and sustaining the natural resources used to demolish and/or produce any kind of infrastructure concerning the architectural, engineering and construction industries, should be factored into Environmental Impact Assessments (EIA), as part of a government's waste management strategy. In other words, this should be a preliminary aspect of the implementation of a waste management strategy. However, ideally, to fully implement a preventative waste management strategy, the range of projects for which EIA's are required should not be restricted, but should be extended to any building site. This paper further suggests that EIA's should be tailored to ensure the sustainability of our natural, used and renewable resources as far as possible. This would assist furthering the goals of the United Nations 2030 Agenda for Sustainable Development. However, to be effective, this approach requires the incorporation of a mandatory protocol involving a process similar to Natural Capital Accounting (NCA) into all associated contracts, standard or bespoke. The scope of this paper will therefore outline what NCA is, and then why it is relevant, considering how it may be used to contribute to a more sustainable EIA for the prevention of waste. It will then briefly consider the role of industry and government before concluding that its implementation should assist the reduction of overall waste of environmental and related resources arising from the said industries. This paper has used a qualitative method based on grounded theory. It involves an exploratory method initially using an inductive approach to generate data, and from this collection of data, key questions are generated to deduce results. The analysis examines, compares and contrasts relevant literature concerning what is NCA as well as how it may be implemented. Research conducted by academics from a range of disciplines, environmental, business, engineering and construction academics, organisations and case studies has been drawn on to consider the transferability of NCA methods to the management of sustainable infrastructure.

This paper proposes a multicriteria decision model based on MAUT (Multiattribute Utility Theory) incorporated into an RCM (Reliability Centered Maintenance) approach in order to provide a better assessment of the consequences of failure, allowing a more effective maintenance planning. MAUT provides an evaluation of probability distributions on each attribute as well as trade-offs involving lotteries. The model proposed takes advantage of such evaluations and it also restructures consequence groups established in an RCM approach into new five dimensions. As a result, overall indices of utility are computed for each failure mode analyzed. With these values, the ranking of the alternatives is established. The decision-maker’s preferences are taken into account so that the final result for each failure mode incorporates subjective aspects based on the decision-maker’s perceptions and behavior.
