The boomerang returns? Accounting for the impact of uncertainties on the dynamics of remanufacturing systems

Recent years have witnessed companies abandon traditional open-loop supply chain structures in favour of closed-loop variants, in a bid to mitigate environmental impacts and exploit economic opportunities. Central to the closed-loop paradigm is remanufacturing: the restoration of used products to useful life. While this operational model has huge potential to extend product life-cycles, the collection and recovery processes diminish the effectiveness of existing control mechanisms for open-loop systems. We systematically review the literature in the field of closed-loop supply chain dynamics, which explores the time-varying interactions of material and information flows in the different elements of remanufacturing supply chains. We supplement this with further reviews of what we call the three ‘pillars’ of such systems, i.e. forecasting, collection, and inventory and production control. This provides us with an interdisciplinary lens to investigate how a ‘boomerang’ effect (i.e. sale, consumption, and return processes) impacts on the behaviour of the closed-loop system and to understand how it can be controlled. To facilitate this, we contrast closed-loop supply chain dynamics research to the well-developed research in each pillar; explore how different disciplines have accommodated the supply, process, demand, and control uncertainties; and provide insights for future research on the dynamics of remanufacturing systems

Innovation in craft enterprises - Barriers and Success Factors

The economic structure of Germany is undergoing radical changes brought about by far-reaching alterations in the global division of labour, a weakening and modification of demand trends and by the dynamics of technological and organizational innovation. These structural changes affect the craft enterprises as well. In the past craft enterprises mastered these challenges in the competition, in the market and in the technology. Moreover, the craft enterprises are responsible for many innovative products, processes and services as well as for the preservation of jobs and the creation of a large number of new jobs. The aim of our research was to find out craft enterprises which have successfully mastered these challenges within the last years. Furthermore it is important to know something about the problems enterprises had with the adjustment to the structural changes. Discovering and analysing the weaknesses is the necessary condition to remove these weaknesses and to be successful on the markets in the future. Especially innovative enterprises are expected to have competitive advantages in opposition to enterprises that are not innovative. The paper is based on an empirical survey of 133 craft enterprises in the area of the Chamber of Handicrafts Reutlingen, a mainly rural region within Baden-Wuerttemberg. The craft enterprises in this area were examined with standardized questionnaires and interviews. The main focus in our survey was placed on variables, which describe the innovative behaviour and the information activities of the enterprises. The questionnaire included questions about process and product innovations, the product age and the three fundamental components in the strategic management of enterprises: The attitude to risk, which is proved by the choice of the growth strategy and the regional extension of sales markets. The innovative competence, i.e. the existence of activities in the areas of research and development, construction and design, business planning and staff development. The willingness to learn and the acquisition of knowledge, i.e. the employees' capability and readiness to take up know-how and to realize innovations with this know-how. The paper summarises the most significant results of the study. The examined craft enterprises were divided into two different groups: the especially successful enterprises and the less successful enterprises. Compared with the less successful enterprises, the especially successful enterprises have a stronger attitude to risk, more innovative competences and a higher willingness to learn. The differences are also emphasized by the fact that successful enterprises formulate questions - not only at the beginning of the renewal process but during all their activities. By doing so they question about themselves and their traditional way of solving problems. They organize a permanent knowledge exchange.

Conceptualising the impact of information asymmetry on through-life cost: case study of machine tools sector

Information asymmetry (IA) in terms of contextual variety and importance is one of the most challenging aspects of through-life costing in product-service systems (PSS). IA is an imbalance in the information, data and knowledge shared among the parties involved in a contractual agreement. In manufacturing systems under PSS, interaction and effective communication among several parties who are involved in a contractual agreement, rely on the continuity and accuracy of information and context. In such systems, contextual variety exhibits complexity and uncertainty in through-life costing and subsequently in PSS cost assessment. Although the economic aspect of PSS has been studied previously, the impact of IA on through-life cost and for different PSS solutions has not been detailed. Considering manufacturing value chains, this paper introduces a new concept of PSS-hierarchy to perform through-life costing in the presence of IA for various PSS solutions. Moreover, this paper proposes a generic life-cycle model for different PSS solutions to assess the total cost of ownership (TCO). The proposed model has been developed to support decisions on contract design in manufacturing systems. This study considers the manufacturer, service provider and customer perspectives to develop the TCO model using a machine tool manufacturing case study

Evolution of Supply Chain Collaboration: Implications for the Role of Knowledge

Increasingly, research across many disciplines has recognized the shortcomings of the traditional “integration prescription” for inter-organizational knowledge management. This research conducts several simulation experiments to study the effects of different rates of product change, different demand environments, and different economies of scale on the level of integration between firms at different levels in the supply chain. The underlying paradigm shifts from a static, steady state view to a dynamic, complex adaptive systems and knowledge-based view of supply chain networks. Several research propositions are presented that use the role of knowledge in the supply chain to provide predictive power for how supply chain collaborations or integration should evolve. Suggestions and implications are suggested for managerial and research purposes

Sustainable typography

We need to radically re-think typography for text-rich business documents & publications (not referring to books). Most designers assume people have time to read. In reality the following occurs: Observations: 1) We browse/forage (71%) then read (11%) 2) People have different time tolerances and requirements for detail i.e. the same information is required to different levels of detailing dependent on the time the reader can allocate to it (Senior directors will have less time than juniors). 3) People want choice as to whether they wish to view information on paper, i-phone, PowerPoint or via web/screen. 4) Most publications do not follow the cognitive principles of how we are Œwired‚ to interpret visual signals. Message-based Design & Message-based Writing (MBD/MBW) is a system that addresses these 4 points and allows key messages to be understood prior to reading simply by scanning the page with its embedded Œvisual hooks‚ to draw the reader in. Thus it overcomes Œfilter failure‚ a phrase coined and first used by Clay Shirky at the Web 2.0 Expo. It collapses to a summary and exploits the way we are wired. Additionally it caters for up to 4 time tolerances of readers and morphs‚ from paper to screen effortlessly

The role of public policy in stimulating radical environmental impact reduction in the automotive sector: The need to focus on product-service system innovation

This is the post-print version of the Article. The official published version can be accessed from the link below - Copyright @ 2010 InderscienceProduct-service system (PSS) innovation is a promising approach to address sustainability challenges in the automotive industry. Starting form this assumption, this paper presents and discusses the potential contribution that policy measures can have in fostering the automotive sector in innovating on a PSS level. A set of policy instruments (general instruments and specific PSS-targeted ones) are presented and classified, underlining the effects they could produce at the company and environmental levels. In order to effectively support sustainable PSS diffusion in the automotive industry, the paper suggests the integration of general policy measures (such as internalisation of external costs, extended producer responsibility programmes and informative policies), with the PSS-targeted ones (such as Green Public Procurement focused on sustainable PSS, support of companies in acquiring information related to PSS, support of demonstrative pilot projects). In addition, the paper suggests the necessity to involve actively universities and research centres
