    abstract = "Abstract Institutional barriers and constraints in developing countries require new supply chain models where economic, social and ecological aspects are integrated. Sustainable supply chain management discourse has focused on ecological aspects and neglected social issues, while Base of the Pyramid studies have neglected ecological considerations. This study links the sustainable supply chain management discourse with insights from Base of the Pyramid studies in order to suggest an integrated sustainability perspective. This work adopts a multiple case study design based on secondary data analysis in order to investigate supply chain concepts of 18 successful products and develop sustainable supply chain models in the areas of sourcing, making and delivering. Findings suggest that by employing localized and simplified approaches, companies targeting low-income markets can overcome existing local institutional barriers. We conclude that employing simplified and localized approaches to supply chains and simultaneously integrating local communities in the value creation activities can serve as success factors. Therefore, by linking sustainable supply chain with the Base of the Pyramid strategies discourse, we fill an important research gap in the literature. From a practitioner's perspective, the derived supply chain models serve as best practices for managers of multi-national companies, local entrepreneurs, non-governmental organizations and political institutions designing, operating and regulating supply chains for low-income markets."

    abstract={The unawareness of production planners about the interaction of key performance indicators (KPIs) in manufacturing systems and misinterpretations of system states often leads to problems when they try to improve them. Exemplary, the lead time syndrome (LTS) represents one of these counterproductive actions. While planners aim to improve due date reliability by planned lead time adjustments, the result is often an aggravation of due date reliability. This is due to human behaviour in the decision-making process, which can be biased. Despite its potential to improve the logistic performance, human needs were out of scope of recent investigations in the field of logistics. The aim of this paper is to close this research gap by means of a case study and research on human behaviour in the field of psychology. The result is the determination of guidelines to improve the logistic performance in future decision-support systems by considering human needs.}

    abstract="Transport risks in supply chains have increasingly lead to significant capital losses. Insurance claims against such losses have grown accordingly, while simultaneous advances in technology lead to continuously larger volumes of data recorded. Traditional risk evaluation methods in insurance struggle to account for rising supply chain complexity which is reflected by growing amount and dimensionality of supply chain data. Therefore decision-makers in the transport insurance industry need new ways of appropriate knowledge representation to support transport insurance providers with daily tasks such as premium tariffing. This paper presents a method based on multidimensional scaling (MDS) for the identification of groups of similar claims as a first step towards the improvement of supply chain risk evaluation and forecasting. We show the application potential of transforming and visualising transport damage claims data as the basis for developing decision support systems (DSS) to support transport insurance providers in tasks such as premium tariffing as well as transport and supply chain managers in risk mitigation and prevention activities."

    abstract="Frugal innovation gains momentum in literature and practice as the next important management approach transferred from East to West after lean. The two paradigms have launched powerful ideas challenging the traditional Western approaches, with frugal innovation being the most recent. This paper focuses on the application of lean management and frugal innovation in the field of engineering. The principles employed during the design stages are responsible for a high percentage of logistics costs and consequently influence significantly logistics processes. Therefore, we highlight similarities and differences of the two approaches, and show how to combine the underlying principles in order to develop more efficient products with efficient production processes especially for cost-sensitive consumers in both developing and developed countries. The implications of lean and frugal engineering for procurement, production, distribution and disposal logistics are relevant not only for sustainability managers, product or logistics managers concerned with sustainability aspects but also for executives aiming to expand their operations in developing countries."

    abstract="The term 'synchronization' in manufacturing refers to the provision of the right components to the subsequent production steps at the right moment in time. It is still unclear how manufacturing system characteristics impact synchronization. Thus, the purpose of this paper is to investigate the effect of manufacturing systems' characteristics on the emergence of logistics synchronization in them. We conduct a discrete-event simulation study to examine the effect of three system characteristics: (1) material flow network architecture, (2) work content variation, and (3) order arrival pattern. Our findings suggest that the material flow network architecture and the work content variation are related to logistics synchronization. Linear manufacturing systems with stable processing times such as flow shops operate at high logistics synchronization levels, while highly connected systems with high variability of processing times such as job shops exhibit lower synchronization levels."

New ERAMUS MUNDUS Interns in PLN Workgroup

In mid-september, the PLN workgroup welcomed Choirunnisa Fatima (from the Bandong Institute of Technology in Indonesia) and Dang Gia Huy (from the Vietnam National University Ho Chi Minh City) as research interns.

The two students are part of the gLINK exchange scheme between institutions in Asia and Europe, funded under the Erasmus Mundus program of the European Union. They will stay with the workgroup for a total of ten months, taking courses at Jacobs University as well as supporting the research of the workgroup.

Prof. Bendul in t&m

tundm_3-2016_CoverA story about Prof. Bendul and the work of the PLN workgroup is on the cover of the most recent issue of t&m (3/2016), the membership magazine of the German Association of Industrial Engineers (VWI).

The story covers the workgroup’s approach to research, industry projects, and teaching in the context of digitalization in production and logistics (“Industry 4.0”).

The magazine is complimentary for all VWI members but may also be ordered separately.

New Paper in CIRP Annals of Production Technology

A new paper by current and former members of the PLN-Workgroup has been published in the highly acclaimed Journal CIRP Annals of Production Technology, edited by the International Academy for Production Engineering (CIRP).

The paper, entitled “Lead time instability and its mitigation in production work systems” is the result of a collaboration with Neil Duffie from the University of Wisconsin-Madison. It continues a research stream at the PLN workgroup into the effects of planned lead time adjustments on manufacturing performance.

In this paper, dynamic models are used to characterize lead time instability in two approaches to work system lead time adjustment. Minimum damping is calculated as a function of lead time adjustment parameters. Industrial data are used to illustrate how the approach provides guidance in selecting production planning and control parameters, with the goal of ensuring stability as a key dynamic foundation for satisfying work system logistic performance targets.

Successful PhD Defense by Adél Németh

On Monday, May 2nd, Adél Németh successfully defended her PhD Thesis entitled “Market power versus efficiency defense in the European Commission’s merger policy: evidence on airline mergers”.

Her dissertation committee was comprised of Prof. Hans-Martin Niemeier (Hochschule Bremen) and Jacobs University Professors Prof. Gert Brunekreeft and Prof. Julia Bendul.

In her PhD-Thesis Dr. Németh investigated the circumstances and consequences of decisions on mergers in the airline industry made by European antitrust authorities on airline mergers. She argues that the decisions took into consideration market power, yet failed to consider aspects of market efficiency.

The thesis is available online through the Jacobs University Library.
