To achieve this, it is essential that a complete rethink-ing of the communication strategy of those responsible for the company takes place.}, language = {en} } @inproceedings{BuchholzJeschkeKappeletal.2019, author = {Buchholz, Wolfgang and Jeschke, Felix and Kappel, Antonia and Ruppe, Cathrin}, title = {One way or another - The relationship between trust and transparency in buyer-supplier relationships}, series = {IPSERA Conference proceedings}, booktitle = {IPSERA Conference proceedings}, pages = {1 -- 14}, year = {2019}, abstract = {Based on a variety of environmental, technological, and product-orientated changes, there has been a shift towards increased collaboration between buyers and suppliers.

The impact of SNM on purchasing performance}, series = {IPSERA Conference proceedings}, booktitle = {IPSERA Conference proceedings}, pages = {1 -- 19}, year = {2019}, abstract = {Buying firms lack transparency about the supplier relationships in their networks. The applica-tion of dedicated tools such as Supply Network Mapping (SNM) can help to visualize and analyze these relationships. However, the impact of such tools on the purchasing performance has not been explored yet. Moreover, companies with different competitive strategies might have different motivations to use these tools. Therefore, this paper tests the impact of supplier relationship information and SNM on the purchasing performance on a large sample of 624 purchasers. A multi-group analysis in structural equation modeling estimates the impact of a cost leadership versus a differentiation strategy on cost saving and innovation performance. We show that information quality and SNM indeed improve the purchasing performance. Moreover, cost leaders use SNM if they know their supplier relationships with sub-suppliers, while innovation leaders use it if they know their supplier relationships with other customers. Hence, our results prove the usefulness of the SNM tool and give recommendations for its use depending on a company's competitive strategy.}, language = {en} } @inproceedings{BuchholzKappelSchiele2019, author = {Buchholz, Wolfgang and Kappel, Antonia and Schiele, Holger}, title = {Knowing your suppliers: people or media as key sources of information?}, series = {IPSERA Conference proceedings}, booktitle = {IPSERA Conference proceedings}, pages = {1 -- 21}, year = {2019}, abstract = {Most companies have realized the high importance of becoming the preferred customers of their suppliers to obtain preferential resource allocation. However, they cannot evaluate their own customer attractiveness properly. In order to make the assessment of the own customer status possible, this paper analyzes the impact of several information sources on the preferred customer status knowledge, supplier satisfaction knowledge and knowledge of alternative supplier relationships with other customers. Testing these hypotheses on a sample of 624 pur-chasers, we show that people provide more relevant information on the company's strategic positioning than media. In particular, the suppliers, competitors and other actors are very im-portant information sources. Following our findings, purchasers should adopt their activities in order to better anticipate their suppliers' intention and the customer treatment that they can expect from their suppliers.}, language = {en} } @inproceedings{BueckerSzepannekBieceketal.2019, author = {B{\"u}cker, Michael and Szepannek, Gero and Biecek, Przemyslaw and Gosiewska, Alicja and Staniak, Mateusz}, title = {Transparency of Machine Learning Models in Credit Scoring}, series = {CRC Conference XVI Papers}, booktitle = {CRC Conference XVI Papers}, editor = {Crook, Jonathan}, publisher = {Credit Research Center, University of Edinburgh}, address = {Edinburgh}, pages = {1 -- 1}, year = {2019}, abstract = {A major requirement for Credit Scoring models is of course to provide a risk prediction that is as accurate as possible. In addition, regulators demand these models to be transparent and auditable. Thus, in Credit Scoring very simple Predictive Models such as Logistic Regression or Decision Trees are still widely used and the superior predictive power of modern Machine Learning algorithms cannot be fully leveraged. A lot of potential is therefore missed, leading to higher reserves or more credit defaults. This talk presents an overview of techniques that are able to make "black box" machine learning models transparent and demonstrate how they can be applied in Credit Scoring. We use the DALEX set of tools to compare a traditional scoring approach with state of the art Machine Learning models and asses both approaches in terms of interpretability and predictive power. Results show that a comparable degree of interpretability can be achieved while machine learning techniques keep their ability to improve predictive power.}, language = {en} } @inproceedings{Chak2019, author = {Chak, Choiwai Maggie}, title = {Interactive dynamics in regional and local health community-academic partnerships: Impact of group climate on partner engagement and collaborative success}, series = {Presentation at CMOB Research Carrousel "Changing Health Care through Medical Leadership and Engagement" (25.01.2019), Enschede, The Netherlands}, booktitle = {Presentation at CMOB Research Carrousel "Changing Health Care through Medical Leadership and Engagement" (25.01.2019), Enschede, The Netherlands}, year = {2019}, language = {en} } @inproceedings{FeldmannDelkeWasserman2019, author = {Feldmann, Carsten and Delke, Vincent and Wasserman, Michael E.}, title = {Strategically Aligning Additive Manufacturing Supply Chains for Sustainability and Effectiveness}, series = {International Federation of Automatic Control (IFAC): Intelligent Manufacturing Systems (IMS 2019) Proceedings}, booktitle = {International Federation of Automatic Control (IFAC): Intelligent Manufacturing Systems (IMS 2019) Proceedings}, address = {Oshawa, Ontario, Canada}, issn = {2405-8963}, pages = {260 -- 264}, year = {2019}, abstract = {This paper builds on a previously developed framework that integrated additive manufacturing, life-cycle analysis, and value creation (Feldmann \& Kirsch, 2019) by exploring conditions related to the life-cycle approach that would require alignment among suppliers, additive manufacturing firms, and customers. This extension creates a bridge to aid implementation of taking a sustainability approach to additive manufacturing. In order to develop this extension, we distinguish between direct/indirect customers and internal/external customers and then create a matrix of incentives and cognitive frames that we believe will help companies interested in large-scale AM improve both the speed and the effectiveness of AM adoption. We provide an organizing framework that managers can use to create a supply chain that is aligned around closed-loop principles that will help speed adoption and move closer to sustainable goals that exist for AM technologies. These include reduced raw material use, reduced scrap and material overage, and reduced rework, and lower transportation costs. The goal is to attain often-conflicting goals of lower long-term costs and decreased environmental footprint. Using our extension, we believe we can provide a useful framework to help managers implementing advanced manufacturing technologies to achieve lower costs and greater environmental sustainability by creating a common supply chain framework around customized, on-demand products.}, language = {en} } @inproceedings{FeldmannKirsch2019, author = {Feldmann, Carsten and Kirsch, Therese}, title = {Increasing the Sustainability of Manufacturing Processes: Ecological Impacts of Additive Manufacturing}, series = {Production Engineering and Management}, booktitle = {Production Engineering and Management}, editor = {Padoano, Elio and Villmer, Franz-Josef}, publisher = {OWL University of Applied Sciences and Arts}, address = {Lemgo}, organization = {Technische Hochschule Ostwestfalen-Lippe}, isbn = {978-3-946856-04-7}, pages = {63 -- 76}, year = {2019}, abstract = {Digitalization and sustainable development are goals of the global community, but can they also be achieved simultaneously? This article investigates the impacts of additive manufacturing (AM) on sustainable production and consumption. The use of AM technology as a means of digitalizing manufacturing processes is assessed through a qualitative life cycle analysis. The model developed for this purpose provides a structure for an analysis of the general ecological effects of AM. The systematics of the life cycle model also supports a company-specific assessment. AM can have a positive impact on achieving sustainable development with regards to ecological effects, particularly by reducing the consumption of resources in production and distribution. However, there are also negative ecological impacts of this technology, such as rebound effects and high energy consumption, which vary depending on the application and the printing process. It appears necessary for regulatory policy to intervene to maximize the opportunities for the positive effects of this technology. However, it is important to reduce the risks that contradict the objectives of the 12th Sustainable Development Goal of the UN: sustainability of consumption and production.}, language = {en} }
