A concept of water usage efficiency to support water reduction in manufacturing industry

Increasing pressures on freshwater supplies, continuity of supply uncertainties, and costs linked to legislative compliance, such as for wastewater treatment, are driving water use reduction up the agenda of manufacturing businesses. A survey is presented of current analysis methods and tools generally available to industry to analyze environmental impact of, and to manage, water use. These include life cycle analysis, water footprinting, strategic planning, water auditing, and process integration. It is identified that the methods surveyed do not provide insight into the operational requirements from individual process steps for water, instead taking such requirements as a given. We argue that such understanding is required for a proactive approach to long-term water usage reduction, in which sustainability is taken into account at the design stage for both process and product. As a first step to achieving this, we propose a concept of water usage efficiency which can be used to evaluate current and proposed processes and products. Three measures of efficiency are defined, supported by a framework of a detailed categorization and representation of water flows within a production system. The calculation of the efficiency measures is illustrated using the example of a tomato sauce production line. Finally, the elements required to create a useable tool based on the efficiency measures are discussed

Job flows, jobless recoveries, and the Great Moderation

This paper uses new data on job creation and job destruction to find evidence of a link between the jobless recoveries of the last two recessions and the recent decline in aggregate volatility known as the Great Moderation. The author finds that the last two recessions are characterized by jobless recoveries that came about through contrasting margins of employment adjustment—a relatively slow decline in job destruction in 1991-92 and persistently low job creation in 2002-03. In manufacturing, he finds that these patterns followed a secular decline in the magnitude of job flows and an abrupt decline in their volatility. A structural VAR analysis suggests that these patterns are driven by a decline in the volatilities of the underlying structural shocks in addition to a shift in the response of job flows to these shocks. The shift in structural responses is broadly consistent with the change in job flow patterns observed during the jobless recoveries.Job analysis ; Employment ; Unemployment

A review of information flow diagrammatic models for product-service systems

A product-service system (PSS) is a combination of products and services to create value for both customers and manufacturers. Modelling a PSS based on function orientation offers a useful way to distinguish system inputs and outputs with regards to how data are consumed and information is used, i.e. information flow. This article presents a review of diagrammatic information flow tools, which are designed to describe a system through its functions. The origin, concept and applications of these tools are investigated, followed by an analysis of information flow modelling with regards to key PSS properties. A case study of selection laser melting technology implemented as PSS will then be used to show the application of information flow modelling for PSS design. A discussion based on the usefulness of the tools in modelling the key elements of PSS and possible future research directions are also presented

Job Flows and the Recent Business Cycle: Not All "Recoveries" Are Created Equal

The last two economic downturns are notable for their slow labor market recoveries. Yet, the behavior of their underlying gross job flows is quite different. The 1990-92 period had a relatively slow decline in job destruction, while the 2001-03 period had a large, persistent decline in job creation that occurs across most industries. The dynamics of the latter period run counter to the conventional wisdom that large movements in job destruction drive business cycles. Evidence spanning the entire postwar period suggests that job creation is at a historic low, and that its recent patterns are part of decades-long decline in the magnitude and volatility of job reallocation.Job Reallocation; Business Cycles; Employment Fluctuations

Contribution of two diagnosis tools to support interface situation during production launch

Organised by: Cranfield UniversityFirms are urged to constantly introduce new products. Hence, the New Product Development process should be mastered, especially its final phase, the production launch. This paper addresses the critical issue of the information exchange during production launch. Two diagnosis tools considering production launch as a key interface are presented. They permit to examine the information flows, to highlight their weaknesses and hence to find solutions for further improvements. This paper also presents the results of a case study where the diagnosis tools were implemented during a switchgear development project.Mori Seiki – The Machine Tool Compan

Cultivating Collaborative Improvement: An Action Learning Approach

As competitive pressure mounts to innovate in the global knowledge economy, many organizations are exploring new ways of collaborating with their supply chain partners. However, the process of implementing collaborative initiatives across disparate members of supply networks is fraught with difficulties. One approach designed to tackle the difficulties of organizational change and inter-organizational improvement in practice is `action learning¿. This paper examines the experiential lessons that arise when cultivating collaborative improvement in an interorganizational learning environment. The authors, acting as action researchers, facilitated a practical learning program in an Extended Manufacturing Enterprise involving a large system integrator in the automotive industry and three of its\ud suppliers. Based on this experience, a practical learning model is offered to promote and facilitate inter-organizational change as part of a collaborative improvement process

Eco‐Holonic 4.0 Circular Business Model to Conceptualize Sustainable Value Chain Towards Digital Transition

The purpose of this paper is to conceptualize a circular business model based on an Eco-Holonic Architecture, through the integration of circular economy and holonic principles. A conceptual model is developed to manage the complexity of integrating circular economy principles, digital transformation, and tools and frameworks for sustainability into business models. The proposed architecture is multilevel and multiscale in order to achieve the instantiation of the sustainable value chain in any territory. The architecture promotes the incorporation of circular economy and holonic principles into new circular business models. This integrated perspective of business model can support the design and upgrade of the manufacturing companies in their respective industrial sectors. The conceptual model proposed is based on activity theory that considers the interactions between technical and social systems and allows the mitigation of the metabolic rift that exists between natural and social metabolism. This study contributes to the existing literature on circular economy, circular business models and activity theory by considering holonic paradigm concerns, which have not been explored yet. This research also offers a unique holonic architecture of circular business model by considering different levels, relationships, dynamism and contextualization (territory) aspects
