Distributed Manufacturing: scope, challenges and opportunities

This discussion paper aims to set out the key challenges and opportunities emerging from distributed manufacturing (DM). We begin by describing the concept, available definitions and consider its evolution where recent production technology developments (such as additive and continuous production process technologies), digitisation together with infrastructural developments (in terms of IoT and big data) provide new opportunities. To further explore the evolving nature of DM, the authors, each of whom are involved in specific applications of DM research, examine through an expert panel workshop environment emerging DM applications involving new production and supporting infrastructural technologies. This paper presents these generalisable findings on DM challenges and opportunities in terms of products, enabling production technologies and the impact on the wider production and industrial system. Industry structure and location of activities are examined in terms of the democratising impact on participating network actors. The paper concludes with a discussion on the changing nature of manufacturing as a result of DM, from the traditional centralised, large-scale, long lead-time forecast-driven production operations to a new DM paradigm where manufacturing is a decentralised, autonomous near end user-driven activity. A forward research agenda is proposed that considers the impact of DM on the industrial and urban landscape.

Can re-distributed manufacturing and digital intelligence enable a regenerative economy? An integrative literature review

This paper uses an integrative literature review to explore the concept of re-distributed manufacturing and the opportunities to deliver more regenerative and resilient systems of production and consumption through the application of circular innovation. The study identified multiple similarities between the drivers of re-distributed and circular models of production and consumption that could be fostered by the use of digital intelligence. A set of criteria for redistributed manufacturing and circular innovation were developed and used to identify 33 existing case studies of consumer goods production. Case study analysis resulted in the identification of three types of re-distributed manufacturing that integrated characteristics of circular innovation. The paper concludes by describing some of the future research challenges in the transition towards re-distributed and circular models of production.

Regulators as ‘agents’: power and personality in risk regulation and a role for agent-based simulation

We critically examine how evidence and knowledge are brokered between the various actors (agents) in regulatory decisions on risk. Following a précis of context and regulatory process, we explore the role power and personality might play as evidence is synthesised and used to inform risk decisions, providing a review of the relevant literature from applied psychology, agent‐based simulation and regulatory science. We make a case for the adoption of agent‐based tools for addressing the sufficiency of evidence and resolving uncertainty in regulatory decisions. Referring to other environmental applications of agent‐based decision‐making, we propose how an agent model might represent power structures and personality characteristics with the attending implications for the brokering of regulatory science. This critical review has implications for the structuring of evidence that informs environmental decisions and the personal traits required of modern regulators operating in facilitative regulatory settings.

Engaging schools in the science of low-energy buildings

This article explores the relationship between the previous UK government’s initiative to rebuild and renew secondary schools, and the requirement for improved education for sustainable development in the UK. The documented research utilized a number of mechanisms to engage with pupils in Leicester city schools to increase their awareness, knowledge and understanding of the science and engineering associated with the design and operation of low-energy school buildings. Workshops, discussions with energy and sustainable development experts and inspirational visits to existing low-energy buildings were employed to develop an appreciation for the importance of energy efficiency and best design practice. The results demonstrate an increase in pupils’ knowledge and understanding of low-energy school design and additionally a rise in those pupils who are interested in science and would consider it as a career option.

Energy Efficiency Status-Quo at UK Foundries: The “Small-Is-Beautiful” Project

Energy efficiency is a critical issue for all manufacturing sectors. In the present paper the energy efficiency of UK foundries was assessed. In the context of this research 80 foundries were studied, 60 were contacted and 10 were visited. General energy data were collected using structured questionnaires, interviewing energy managers and process operators. A number of foundries are operating to a good standard, by employing energy managers and regularly auditing; they are in control of their process and working rigorously to improve their efficiency. Simultaneously though, smaller foundries have not adjusted to the new market demands and are not operating in the most energy efficient manner. Important barriers to energy efficiency in these foundries include lack of knowledge on auditing methods, poor knowledge in managing energy consumption, the inefficiency of individual process steps, production disruptions, aging equipment, personnel behavior, inadequate maintenance and lack of investment, automation and research.

Opportunities for redistributed manufacturing and digital intelligence as enablers of a circular economy

ABSTRACT The linear production of consumer goods is characterised by mass manufacture by multinational enterprises and globally dispersed supply chains. The current centralised model has created a distance between the manufacturer and end user, limiting the opportunity for intelligent circular approaches for production and consumption. Through a mixed method approach, opportunities of circularity are explored for the consumer goods sector. The study presents four lenses to analyse three enterprises through a multi-case study approach to explore the potential of digital intelligence and redistributed manufacturing (RDM) as enablers of circular business models. In addition, the study examines whether Discrete Event Simulation can be used to evaluate the circular scenarios identified through quantifying flows of material that determine traditional economic value (cost/tonne). The mixed method approach demonstrates that, a qualitative systemic analysis can reveal opportunities for circularity, gained through implementing ‘digital intelligence’ and distributed models of production and consumption. Furthermore, simulations can provide a quantified evaluation on the effects of introducing circular activities across a supply chain.
