New types of sustainable materials are introduced in our markets every year to minimise the environmental impact of products. The search for more environmentally benign materials is crucial in reducing the depletion of non-renewable material resources. Recent literature indicates that there is a growing interest and rapid technological progression from various industry stakeholders on this matter. Nevertheless, the sustainability issues pursued by designers and other material developers are still ambiguous. The overall aim of this research is to develop new understanding of the sustainable materials being developed and applied in product design. Seventy-two material-centred design projects are analysed in terms of resource renewability and resource origin. The data obtained are further classified according to the material group and products produced with such materials. Renewable materials make up half of the materials used. Moreover, waste materials comprise up to half of the materials used. Three materials groups were found to be more frequently used, namely natural composites, synthetic polymers and organic materials. Most of these materials are being made into furniture, household objects and clothing and accessories. Within the natural composites and organic materials, various extraordinary materials were used, reflecting the dynamicity of designers’ work and experimentation with materials. As for synthetic polymers, recycled plastics are the main materials used and this is not surprising given their abundance in the environment. In general, the application of sustainable materials seems to be at its infancy but explorations are vibrant and progressive. The impact of these materials in the mainstream market is unknown and other sustainability factors need further evaluation. As such, design as a discipline is yet to facilitate the uptake of these materials.

The construction sector is currently undergoing a shift from stick-built construction techniques to modular building systems. If construction supply chains are to support this transformation, they need to be modified and strengthened using an adapted logistics system. The aim of this study is to establish a mathematical model for the logistics of modular construction covering the three common tiers of operations: manufacturing, storage and construction. Previous studies have indicated that construction site delays constitute the largest cause of schedule deviations. Using the model outlined in this paper we seek to determine how factory manufacturing and inventory management should be adapted to variations in demand on the construction site. We propose a Mixed Integer Linear Programming model that captures construction scenarios with demands for modular products that are either foreseeable or abruptly disrupted. The use of the model is illustrated through a case study of bathroom pods for a building project. The model outputs include supply chain configurations that reduce total costs across a range of scenarios. The model could serve as a decision support tool for modular construction logistics.

Morrone M, Garion C, Aurisicchio M, et al., 2017, A coupled multiphysics FEM model to investigate electromagnetic, thermal and mechanical effects in complex assemblies: the design of the High Luminosity Large Hadron Collider beam screen, Applied Mathematical Modelling, ISSN: 0307-904X
In the framework of the High Luminosity Large Hadron Collider (HL-LHC) project, new beam screens will be installed by 2024 within the cold bore of the superconducting magnets. The beam screen is an octagonal shaped pipe that shields the 1.9 K magnet cryogenic system from the heat loads and damage to the magnet coils that would be otherwise induced by the highly penetrating collision debris. It also ensures that proper vacuum conditions required for the stability of the beam are met.A failure scenario of the beam screen is represented by the magnet quench, a resistive transition of the superconducting magnets, that can compromise its mechanical integrity. During a quench the magnet gradient of the quadrupole, in which the beam screen is inserted, decays from 140 T/m to about 0 T/m in 0.4 s inducing high magnitude forces in the assembly. Understanding the magnetic, thermal and mechanical behaviours of the beam screen assembly during the quench is critical to enable its effective design and operation. A numerical model, that can accurately predict the behaviours of the beam screen during a magnet quench, has been developed.Compared to the analytical formulations used to design the beam screen currently installed in the LHC, the multiphysics FEM model developed in this research introduces multiple elements of novelty and improved performance. First, self-inductance effects are accounted for and found to reduce the induced forces up to approximately 2000 % at high electrical conductivity values. Second, the one-way and two-way coupling of the magnetic with the mechanical and thermal interfaces are explored and the best trade-off is defined. Third, the mechanical response of the assembly is evaluated dynamically over the evolution of the magnetic field decay rather than just in a quasi-static manner. Fourth, three dimensional geometries can also be studied enabling the design of the components to be placed along the beam axis.The model has been verified by comparison to a

Copyright © 2015, Association for the Advancement of Artificial Intelligence (www.aaai.org). All rights reserved. IBIS (Issue Based Information System) provides a widely adopted approach for knowledge representation especially suitable for the challenging task of representing wicked decision problems. While many tools for visualisation and collaborative development of IBIS graphs are available, automated decision support in this context is still underdeveloped, even though it would benefit several applications. QuAD (Quantitative Argumentation Debate) frameworks are a recently proposed IBIS-based formalism encompassing automated decision support by means of an algorithm for quantifying the strength of alternative decision options, based on aggregation of the strength of their attacking and supporting arguments. The initially proposed aggregation method, however, may give rise to discontinuities. In this paper we propose a novel, discontinuity-free algorithm for computing the strength of decision options in QuAD frameworks.We prove that this algorithm features several desirable properties and we compare the two aggregation methods, showing that both may be appropriate in the context of different application scenarios.

© Springer International Publishing Switzerland 2015. The need of making decisions pervades every field of human activity. Several decision support methods and software tools are available in the literature, relying upon different modelling assumptions and often producing different results. In this paper we investigate the relationships between two such approaches: the recently introduced QuAD frameworks, based on the IBIS model and quantitative argumentation, and the decision matrix method, widely adopted in engineering. In addition, we describe Arg & Dec (standing for Argue & Decide), a prototype web application for collaborative decision-making, encompassing the two methodologies and assisting their comparison through automated transformation.

Understanding product functions is a key aspect of the work undertaken by engineers involved in complex system design. The support offered to these engineers by existing modelling tools such as the Function Tree and the Function Structure is limited as they are not intuitive and do not scale well to deal with real world engineering problems. A research collaboration between two universities and a major power system company in the aerospace domain has allowed the authors to further develop a method for function analysis known as Function Analysis Diagram (FAD) which was already in use by line engineers. The capability to generate and edit these diagrams was implemented in the Decision Rationale editor (DRed) a software tool for capturing design rationale. This article presents the intended benefits of the method and justifies them using an engineering case study. The results of the research have shown that the FAD method has a simple notation, permits the modelling of product functions together with structure, allows the generation of rich and accurate descriptions of product functionality, is useful to work with variant and adaptive design tasks and can co-exist with other functional modelling methods.
