Baxter W, Aurisicchio M, 2018, Ownership by Design, Psychological Ownership and Consumer Behaviour, Editors: Peck, Shu
Ownership is central to the successful design of many offerings. This is made more evident with large contextual shifts in terms of immaterial ownership, ownership by multiple users, and time dependent ownership. Psychological ownership theory links naturally to existing experience design models and is thus useful in approaching how to design for ownership. Designers should consider the motives and routes to ownership described by psychological ownership theory but also the paths to ownership formed through interaction with an object. The result is a new frame for design in which the objective is to create a possession, not simply an object. Designing an object, which is owned, means focusing on the interactions between a user and the object through the entire lifecycle including consideration of when an object enters and exits a person’s possessions. Within this new frame, there are at least four main ways in which designers can create intentional ownership experiences. Specifically, they can help: give meaning to the ownership deprived experiences increasingly prevalent in modern digital and shared contexts; structure the ownership experience; reduce redundant effort made once an object is taken into a person's possession; and mitigate contaminated interaction, which is likely to prevent ownership from occurring.
Bin Bahrudin FI, Aurisicchio M, 2018, The appraisal of sustainable materials, Design 2018, Publisher: Design Society, Pages: 2575-2584, ISSN: 1847-9073
This paper seeks to understand how users appraise and perceive sustainable materials. Using thinking aloud sessions, appraisals of sustainable materials embodied in commercial products were collected from users and categorised. To account for the appraisalof systemic features of materials we have extended a previous categorisation ofmaterial appraisals. We have also investigated the relationships between the appraisal themes of sustainable materials. The results stress the influence of material origin in the appraisal.This understanding is useful to facilitate the uptake of the materials.

© 2018 Elsevier Ltd In the materials selection process, the use of different tools, languages and perspectives frequently causes disagreement between engineers and industrial designers. The aim of the paper is to define an integrated method for materials selection that provides industrial designers with measurable data to support and explain aesthetic decisions on materials. A new method for materials selection consisting of multiple tools structured in a two-step framework is presented. The method is tested through a case study of professional kitchen appliances where metal components are replaced with polymers. The first step involved the application of an established technique to identify polymeric bulk solutions, based on their technical properties. The second step employed a sensory analysis test to choose suitable finishes. Thirty-seven individuals performed the test: the subjects highlighted their main perceptions of metal and metal-look polymer finishes. The research demonstrates that the proposed method is suitable for the evaluation of both technical and sensorial properties of materials. In particular, Mapping test represents a rapid, low cost and effective tool to help industrial designers justify Colour Materials and Finish (CMF) choices with quantifiable information.

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.

Yang X, Aurisicchio M, Mackrill J, et al., 2017, On the products and experiences that make us happy, Pages: 499-508, ISSN: 2220-4334
The study of happiness is receiving increasing attention both in positive psychology and design. A key issue in current literature is the lack of empirical evidence linking products and happiness. We address this examining 87 reports of product-mediated happy experiences and analysing their relations to wellbeing. Six types of products with experiential attributes were reported to contribute more systematically to happiness. Digital devices and food are the two dominant products followed by vehicles, books, clothing & accessories and sport equipment. These products make us happy by creating: hedonic experiences in which we relieve stress, get rest and increase joy; and eudaimonic experiences in which we establish positive social relationships, develop self-identity, achieve personal growth and gain competence and autonomy. In such experiences, products acted as carriers of reflective meanings, and enablers of experiencing. These insights provide an initial mapping of the relationship between products and happiness and suggest approaches to designing products that can bring happy experiences.

Rago A, Toni F, Aurisicchio M, et al., 2016, Discontinuity-free decision support with quantitative argumentation debates, Pages: 63-72
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.
