Investigation of Material Supply Strategies to Increase Resilience in Matrix Production Systems

In order to design a resilient production system, individual system elements have to be flexible and adapt towards changing requirements. In contrast to the prevailing paradigm that complexity in production systems is reduced by standardisation or cycle production, complexity in resilient production systems offers great potential in terms of adaptiveness, robustness and anticipation. Within production control, matrix production is seen as a resilient and versatile system. Flexible routing between work-stations makes it possible to compensate for failures more quickly in the event of a malfunction, flexible logistics and control processes allow the workstations to be controlled and used in a job-specific manner. In this paper, challenges and operating principles of material supply strategies are investigated that have the biggest influence on the design of resilient processes in matrix production. Using a simulation model and scenarios from the automotive sector, the potentials, requirements and parameters for describing resilience are specified

The changing landscape of genetic testing and its impact on clinical and laboratory services and research in Europe

The arrival of new genetic technologies that allow efficient examination of the whole human genome (microarray, next-generation sequencing) will impact upon both laboratories (cytogenetic and molecular genetics in the first instance) and clinical/medical genetic services. The interpretation of analytical results in terms of their clinical relevance and the predicted health status poses a challenge to both laboratory and clinical geneticists, due to the wealth and complexity of the information obtained. There is a need to discuss how to best restructure the genetic services logistically and to determine the clinical utility of genetic testing so that patients can receive appropriate advice and genetic testing. To weigh up the questions and challenges of the new genetic technologies, the European Society of Human Genetics (ESHG) held a series of workshops on 10 June 2010 in Gothenburg. This was part of an ESHG satellite symposium on the 'Changing landscape of genetic testing', co-organized by the ESHG Genetic Services Quality and Public and Professional Policy Committees. The audience consisted of a mix of geneticists, ethicists, social scientists and lawyers. In this paper, we summarize the discussions during the workshops and present some of the identified ways forward to improve and adapt the genetic services so that patients receive accurate and relevant information. This paper covers ethics, clinical utility, primary care, genetic services and the blurring boundaries between healthcare and research

Matrix Production Systems - Requirements and Influences on Logistics Planning for Decentralized Production Structures

In the context of the digital transformation of industry and within the framework of Industrie 4.0 and Factory Planning 4.0, new production-organizational principles with decentralized, modular and freely linked production cells are increasingly being discussed. The principle of matrix production with categorized and standardized work-stations offers an extremely versatile production environment. This can be used to meet the challenge of an increasing number of product variants in variable quantities. This concept is predominantly only considered from a theoretical point of view. Therefore, many aspects regarding the planning and operation of such systems are still open. With the focus on logistics processes, this paper describes the requirements for such flexible, dynamic routing and self-organizing resources in material supply. Fur-thermore, they are investigated in a generic, conceptual model for a matrix production. Based on a reference scenario from the automotive industry, classical parameters from logistics and production organization are taken up. The influences with regard to decentralized material supply concepts and structural differences to flow production are shown by the results of simulation experiments with the generic model

Magdeburg Logistics Model – the smart logistics zone as a concept for enabling logistics 4.0 technologies

Intelligent linking in the context of Industry 4.0 alters the objectives and possibilities of designing logistics solutions in the production economy today and tomorrow [1]. There is a growing need for an expanded theory of logistics that helps to characterize existing solutions as well as systematically develop new solutions and bring them together effectively and efficiently. The objectives are the development of a model of thinking and a procedure model for current and future logistics solutions including Logistics 4.0. The article explains the newly developed "Smart Logistics Zone" (SLZ). The SLZ is defined as a scalable examination and action area for analysis, evaluation, planning, control, regulation and (re-) configuration of logistics solutions [2]. New to the thinking model are the generation of solutions from (logistic) objects, pro-cesses, systems and the relevant infrastructure as well as the scalability of the considered zone. The framework model provides a quantifiable target system. The process model in turn allows a systematic solution development using method and technology databases. Several possible views on logistics, which are considered as aspects in the SLZ, are being elaborated. Other aspects of the presented concept such as intelligence and spatial categories are discussed as well. In the outlook a sample factory serves as a scalable examination area for the SLZ. In its application, the SLZ demonstrates a new perspective on the analysis, planning and evaluation of logistics systems. The approach is designed as a scalable tool. It can be adaptively applicable to various intralogistic and extralogistic problems

The Financial and Economic Aspects of Transport Infrastructure Development in Latvia

This paper is devoted to topical issues in the development of transport infrastructure as a key component of the transport system of Latvia. The level of development of transport infrastructure is measured by specific economic indicators, which in their turn depend on the volume and efficiency of acquisition of sources of funding. The paper sheds light on the economic indicators of the development of the transport infrastructure in Latvia and issues of funding of this sector. The data contained in this paper reveals the size and directions of public investment in the transport infrastructure development. The paper focuses on the necessity to create the effective investment mechanism for financing the transport infrastructure of Latvia as a useful instrument in making investment decisions. Based on the theory of decision making the authors developed Investment Decision-Making Concept, which can be used when selecting investment projects in the field of transport infrastructure and their evaluation. This paper is based on the litera ture review of previously published papers of these authors. The authors refine their conceptual approach for developing an investment decision making mechanism, proposed in earlier papers, and offer recommendations aimed at policy-makers, professionals, academics and those with a broad interest in the field

Theology, Politics and Society: the Missing Link. Studying Religion in the Mamluk Period

The chapter focuses on a few problematic topics which have so far received little attention in contemporary scholarship on religion in the Mamluk period. In particular it tries to shed light on what the author describes as a missing link between theological production and its social and political significance, between theologians and society at large, between ideas about God and their relevance to people\u2019s lives. The article argues that exploring the link between society and theology may be a rewarding research enterprise. An attention to this link is generally missing in scholarship both on the intellectual and the socio-religious history of the Mamluk period. The paper identifies the reasons for this state of affairs and provides a sample of materials that proves that we do not lack the resources for pursuing research in this direction. The paper advocates an interdisciplinary approach where the efforts of experts in Islamic theology and historians interested in religion and society ought to merge
