The analytic network process (ANP) permits to systematically evaluate possible DCs on the basis of a situation-specific decision structure. A systematic development of the decision networks, which is one of the core challenges using the ANP, is supported by the process analysis method which we extend for that purpose. The validity and soundness of the proposed framework are demonstrated by means of a case study. The case study results reveal that omitting aspects of sustainability can lead to unfortunate results.}, language = {en} } @article{KellnerIgl2015, author = {Kellner, Florian and Igl, Johannes}, title = {Greenhouse gas reduction in transport: analyzing the carbon dioxide performance of different freight forwarder networks}, series = {Journal of Cleaner Production}, volume = {99}, journal = {Journal of Cleaner Production}, doi = {10.1016/j.jclepro.2015.03.026}, pages = {177 -- 191}, year = {2015}, abstract = {There are growing concerns in the food industry about how supply chains can be managed in a more sustainable way. When distribution activities are outsourced to a logistics service provider (LSP), shippers need to evaluate the LSPs they may (potentially) engage in order to ensure that supply chain sustainability goals are met. In this paper, we present a methodology for LSP evaluation and focus on the ecological dimension of sustainability. We examine how the network carbon footprint of a real-world distribution system is affected by the LSP network that is chosen to forward goods from production facilities to customers. To do this, we analyze the shipment data of an existing Fast Moving Consumer Goods (FMCG) manufacturer. A quantitative distribution network model is set up to study the network carbon footprint of 125 scenarios. Real-world shipments are forwarded via five generic, idealized types of LSP networks. In total, 625 network carbon footprints, specified by three distribution logistics variables and the structure of the LSP network, have been calculated. The results show that LSP structures practicing a geographically decentralized consolidation of shipments are most efficient in reducing of greenhouse gas (GHG) emissions. Furthermore, the effects of changing the manufacturer's and the LSP's strategies for deciding on the tonnage to be forwarded via the LSP network or moved by direct transports are quantified. Finally, we estimate the GHG effect of improving the capacity utilization of the vehicles that move the products.}, language = {en} } @inproceedings{Kellner2015, author = {Kellner, Florian}, title = {Analysing the greenhouse gas sensitivity of distribution networks}, series = {Global Cleaner Production and Sustainable Consumption Conference}, booktitle = {Global Cleaner Production and Sustainable Consumption Conference}, year = {2015}, language = {en} } @article{Kellner2015, author = {Kellner, Florian}, title = {Insights into the effect of traffic congestion on distribution network characteristics ? a numerical analysis based on navigation service data}, series = {International Journal of Logistics Research and Applications}, volume = {19}, journal = {International Journal of Logistics Research and Applications}, number = {5}, doi = {10.1080/13675567.2015.1094043}, pages = {395 -- 423}, year = {2015}, abstract = {This research studies effects that the average increase in travel times due to road traffic congestion has on characteristics of an existing distribution network.

The use of such data allows the requirements that arise for the traffic analysis of a whole distribution network to be met.

Here, we investigated the 2 opposing effects of selective retrieval in older age. In Experiment 1, we examined 64 younger (20-35 years) and 64 older participants (above 60 years), and manipulated study context access using list-method directed forgetting. Whereas both age groups showed a detrimental effect of selective retrieval on to-be-remembered items, only younger but not older adults showed a beneficial effect on to-be-forgotten items. In Experiment 2, we examined 112 participants from a relatively wide age range (40-85 years), and manipulated study context access by varying the retention interval between study and test. Overall, a detrimental effect of selective retrieval arose when the retention interval was relatively short, but a beneficial effect when the retention interval was prolonged. Critically, the size of the beneficial but not the detrimental effect of retrieval decreased with age and this age-related decline was mediated by individuals' working memory capacity, as measured by the complex operation span task. Together, the results suggest an age-related dissociation in retrieval dynamics, indicating an earlier decline of the beneficial than the detrimental effect of selective retrieval with older age.

After study of the list, half of the participants performed an imagination task supposed to induce a change in mental context, whereas the other half performed a counting task which does not induce such context change. Following presentation of a second list, memory for the original list's target items was tested, either with or without preceding retrieval of the list's nontarget items. Consistent with previous work, preceding nontarget retrieval impaired target recall in the absence of the context change, but improved target recall in its presence. In particular, there was a positive relationship between WMC and the beneficial, but not the detrimental effect of memory retrieval. On the basis of the view that the beneficial effect of memory retrieval reflects context-reactivation processes, the results indicate that individuals with higher WMC are better able to capitalise on retrieval-induced context reactivation than individuals with lower WMC.}, language = {en} } @misc{Ott2015, author = {Ott, Holly C.}, title = {Process Quality Monitoring at Altis Semiconductor}, editor = {The Case Centre,}, organization = {Singapore Management University}, year = {2015}, language = {en} } @misc{Ott2015, author = {Ott, Holly C.}, title = {Using the DMAIC Process Improvement Flow at Hanwag GmbH}, year = {2015}, language = {en} } @misc{Ott2015, author = {Ott, Holly C.}, title = {SPC at Melon Helmets, Production Problem at Melon Helmets}, year = {2015}, language = {en} } @inproceedings{StubenrauchSeligerSchusteketal.2015, author = {Stubenrauch, Franz and Seliger, Norbert and Schustek, Maximilian and Lebedev, Alexey and Schmitt-Landsiedel, Doris}, title = {A 13.56MHz class e power amplifier for inductively coupled DC supply with 95\% power added efficiency (PAE)}, series = {2015 International EURASIP Workshop on RFID Technology (EURFID), Rosenheim}, booktitle = {2015 International EURASIP Workshop on RFID Technology (EURFID), Rosenheim}, pages = {87 -- 93}, year = {2015}, abstract = {Recent development of GaN power transistors with blocking voltages up to 650V enables novel power electronics applications with outstanding performance in high-frequency operation.

Besides a solvent induced shift of the electronic transition frequency, in many cases, a spectral fine structure can be resolved for electronic and vibronic transitions which goes beyond the expected feature of a zero phonon line accompanied by a phonon wing as known from matrix isolation spectroscopy. The spectral shape of the zero phonon line and the helium induced phonon wing depends strongly on the dopant species. Phonon wings, for example, are reported ranging from single or multiple sharp transitions to broad (Δν > 100 cm-1) diffuse signals. Despite the large number of example spectra in the literature, a quantitative understanding of the helium induced fine structure of the zero phonon line and the phonon wing is missing. Our approach is a systematic investigation of related molecular compounds, which may help to shed light on this key feature of microsolvation in superfluid helium droplets.

The usage of resources is still often pictured on a short perspective. Especially the usage of human resources must be sustainable, based on long term balance of interests and supported by procedures and systems that anchor the anabolic balance of interest between company and employee (Moldaschl,2008). Within the management of competencies, culture and values, the "social capital" in terms of an "asset of mutual trust" plays and important role. If the "homo reciprocans" feels to be treated fair his own willingness to cooperate increases (Falk, 2002). Furthermore "Trust in human relations is a binding framework under insecurity and allows decisions and actions that would not be possible based on pure rational information and consideration" (Strasser/ Voswinkel, 1997). The question behind the research paper at hand is: "Is a culture of trust leading to higher employee competence utilization?" This is of relevance as "it is human capability and commitment that distinguishes successful organizations from the rest" (Storay, J. 2007), which is explicitly valid in times of skilled worker shortage. The purpose of this paper is to introduce a research approach to test the correlation between Trust and Employee Competence Utilization (ECU) - embedded in a Business Excellence (BE) setting. Based on a short insight in the theoretical foundation of the basic model behind the empirical study and the subsequent operationalization of the variables the basic empirical methodology is described. With this the paper shows the process of focussing and bounding from the general theoretical relation of Trust and ECU to a specific research question and it's correlating stepwise empirical approach. The paper at hand gives detailed insights in the logic of planning of the empirical test methods as well as the development of the derived interview lines and questionnaires. The findings of this paper broaden the research focus towards the complexity of the two variables, trust and ECU, but simultaneously introduce and suggest an empirical approach to lighten the possibilities of measuring both variables.

Still trust is a resource of strategic relevance since it establishes security, reduces complexity and opens potentials being bigger than simply the reduction of "cost of control". These characteristics are of special interest for management, as competent action is always bound to problem-solving-abilities under circumstances of insecurity. Further to this there are numerous situations where control is not applicable and where we simply don't have full knowledge. Also trust is particular as it bypasses financial efforts and grows through usage; an investment of high amortization though that deserves closer attention of management especially valid in times of skilled worker shortage and with respect to organizational learning as a valuable competitive advantage. The purpose of this paper is to develop direct and indirect measurable on the impact of trust on employee competence utilization and its subsequent realization in a strategic scorecard approach. This is based on a new integrative model in the organizational context applicable for strategicmanagement. With this the objective of the paper is to answer the question if culture of trust is an adequate instrument for strategic management. The empirical evaluation of the model is based on a survey directed to employees of selected companies in a pragmatic mixed methods application. The selected view considers the trust level of employees with regard to management as another individual and the organization itself; personal and institutional trust mechanisms are affected.Thus the employee evaluates its management. As a result, the empirical study suggests that it is possible to specify frameworks for the establishment of trust, and that its impact on competence utilization is moreover significant. However the concept of trust creates challenging requirements on managers. Based on the assumption that employees basically think and act in the sense of the company, benevolence and goodwill must be involved to avoid an opportunistic approach. Further to this accountability, shared norms and freedom to take responsibility need to be proven by behavior. The allowance of constructive seriously taken criticism, problem solving attitude, the acceptance of decisions are further key points for trust supporting frameworks that have to be accepted and shown through behavior.}, language = {en} } @incollection{BolzernKonradNeuertWoschank2015, author = {Bolzern-Konrad, Britta and Neuert, Josef and Woschank, Manuel}, title = {The impact of social capital on employee competence utilization in organizations - Socio-cultural modelling and testing}, series = {Contemporary Approaches of international Business Management, Economics and Social Research, Vol. 3}, booktitle = {Contemporary Approaches of international Business Management, Economics and Social Research, Vol. 3}, publisher = {epubli GmbH}, address = {Berlin}, publisher = {Technische Hochschule Rosenheim}, year = {2015}, abstract = {The consideration of company resources is initially oriented towards the question of whether the actual resources are adequate to achieve the defined goals.

The assumption is made that a culture of trust is the adequate instrument to support employee competence utilization; an aspect being of special interest for strategic management.
