Inderfurth, Karl, Ian M. Langella, Sandra Transchel and Stephanie Vogelgesang (2013): A heuristic approach for the disassemble-to-order problem under binomial yields, in: Tempelmeier, Horst and Heinrich Kuhn (ed.): Proceedings to the Ninth International Conference on Stochastic Models of Manufacturing and Service Operations, 71-78.
Abstract: In disassemble-to-order (DTO) systems randomness of recoverable parts gained from used products creates a major challenge for appropriate planning. Typically, it is assumed that yields from disassembly are either stochastically proportional (SP) or follow a binomial (BI) process. In the case of yield misspecification, it can be shown that the BI yield assumption usually results in a lower penalty than the SP yield assumption. For BI yield, however, a suitable, powerful heuristic is needed in order to facilitate DTO problems olving for complex realworld product structures. We present a heuristic approach that is based on a ecomposition procedure for the underlying non-linear stochastic optimization problem and that can be applied to problems of arbitrary size. A numerical performance study reveals that this heuristic yields close - to - optimal results.

Abstract: The logistics service industry is characterized by a high level of collaboration between logistics customers and providers. In fact, sophisticated, knowledge-intense business models such as fourth party and lead logistics evolved in recent years that are responsible for planning, coordination, and monitoring entire supply chains across logistics companies. The Logistics Service Engineering and Management (LSEM) platform is a service-oriented infrastructure for the development and management of collaborative contract logistics enabling fourth party and lead logistics. The service modeling framework (SMF) is a central element of the LSEM-platform. It allows users of the platform to define, manage and combine logistics services from different providers and allows for an integrated view on complex services setups. In this paper, the Service Meta Modeling Editor is presented as an essential part of the SMF. It allows connecting and integrating various types of service models and avoids the need to define and maintain a complex, global service model. Instead a comprehensive service model is built bottom-up in that elements from different models are linked on a metamodel level.
Liu, Heng, Hanno Friedrich and Li Zhang (2013): Modeling of Freight Transport Distribution in Germany – A Discussion of Traditional Distribution Models and a new Procedure for Performance Improvement: Selected Proceedings of the WCTRS Conference on Transportation Research.
Abstract: This work aims to discuss modeling issues on solving the transport distribution problem in freight transport. The traditional distribution model – the Gravity Model – is introduced in detail with the focus on its forecasting capability of freight transport distribution. Through analyses on the base of observed and predicted data of freight transport in Germany, it is found that, compared to applying the Gravity Model, directly balancing the observed distribution from the last period using the Furness Method can generate more closer predictions to the official predictions in a planning project of the German Federal Ministry of Transport, Building and Urban Development. However, the re is a doubt about whether this Furness Method itself brings about an impact on the deterrence exponent. Based on the proposition that the Furness Method dilutes the deterrence effect of transport costs, a compensating procedure is developed in this work as a supplement to the traditional process, offering a new thinking to improve the prediction performance of distribution models.

Abstract: There is evidence that the shipping industry could achieve energy efficiency gains through the implementation of new technologies, with considerable reductions of fuel costs and emissions to air in the sector. Although the cost reducing effects of some new technologies are well established, companies appear reluctant to innovate despite the financial and societal benefits, as a result of what is referred to as the energy efficiency gap. The global emission impacts of the shipping industry, most notably of greenhouse gases, sulphur and nitrogen oxides are increasingly attracting the attention of regulators, non-governmental organisations and the media, and shipping companies are under pressure to find new ways to reduce their emission footprint. Understanding the determinants of the energy efficiency gap in shipping is then critical in improving the environmental profile of the industry. This paper presents the results of a survey among Norwegian shipping companies aimed at gaining a better understanding of the barriers to implementation of new cost saving technologies. The paper assesses the technical barriers that have traditionally been indicated as the main cause of the energy efficiency gap in shipping. The paper results indicate that next to technical factors, important barriers are constituted also by managerial practices and legal constraints.

Abstract: Business and scientific workflow management systems (WfMS) offer different features to their users because they are developed for different application areas with different requirements. Research is currently being done to extend business WfMSs by functionality that meets requirements of scientists and scientific applications. The idea is to bring the strengths of business WfMSs to e-Science. This means great effort in re-implementing features already offered by scientific WfMSs. In our work, we investigated another approach, namely combining business and scientific workflows and thus harnessing the advantages of both. We demonstrate a prototype that implements this idea with BPEL as business workflow language and Pegasus as scientific WfMS. Our motivation is the fact that the manual work to correctly install and configure Pegasus can be supervised by a BPEL workflow to minimize sources of failures and automate the overall process of scientific experimenting.

Abstract: The success of an enterprise is largely determined by its ability andflexibility to react to changes and its business process stability and safeness. Innovative technologies help to improve the execution and management of business processes and ensure that a competitive position can be achieved or enhanced. Radio frequency identification is such an innovative technology with a high potential of optimisation within business processes for example for reduction of processing time and failure rates. By means of a practical case study this paper gives recommendations and shows how RFID can improve business processes.

Hering, Thomas, André Ludwig and Bogdan Franczyk (2009): Proliferation in Service Types: Towards a Unifying Taxonomy of Service Types, in: Fähnrich, Klaus-Peter (ed.): Practitioner Track - International Symposium on Services Science (ISSS'09), Univ.: Leipzig.
Abstract: SSME and SOA are strongly connected perspectives. SOA modelingprocedures, SOA management methodologies, SOA role concepts, and many otherimportant aspects heavily depend and base on specific SOA service types defined in aservice taxonomy. However, currently we are far from a consistent taxonomicunderstanding which causes communication problems regarding nearly all SOA issueshampering research as well as implementation efforts in this field. This paper reflects thecurrent state of discussion by mapping several relevant proposals and presents a basicservice taxonomy aiming at stopping the proliferation of service types. This basictaxonomy can be used as a basis for domain- or project-specific taxonomic refinements.

Abstract: Service oriented architecture (SOA) has emerged as a popular software paradigm for integrating distributed applications. Services are generally regarded as interoperable building blocks for constructing, integrating, and merging applications. However, existing SOA based solutions often focus on solving technical integration problems while neglecting business-level capabilities which are most important for organizations. In this paper, we introduce the notion of capabilities as an important concept for business management. We identify major shortcomings of the existing service based solutions and outline a novel approach for capability oriented configuration and management that can react to the dynamically changing nature of business integration environments.
