    • Safety Stock Optimization in Two-Echelon Assembly systems: Normal Approximation Models

      Desmet, Bram; Aghezzaf, El-Houssaine; Vanmaele, Hendrik (International Journal of Production Research, 2010)
      This paper tackles the problem of optimising safety stocks in a two-echelon assembly system. It presents and discusses several approximation models for the assembly lead-time under the assumption of normality of the assembly demand and normality of components’ nominal lead times. These approximation models are subsequently used to optimise safety stocks throughout a two-echelon assembly system. They are then tested on a particular two-echelon N-identical component assembly system. The obtained results are compared with the results of a discrete event simulation. Finally, it is shown that lead-times and safety stock results already obtained for a two-echelon distribution system can also be derived without difficulty from those of two-echelon assembly systems.
    • Same same, but different: Eine Analyse des Humankapitals weiblicher und männlicher Aufsichtsräte in Deutschland

      Fehre, Kerstin; Spiegelhalder, Rebecca (Schmalenbachs Zeitschrift für betriebswirtschaftliche Forschung, 2017)
      Der Beitrag untersucht die Frage, ob sich Frauen und Männer im Aufsichtsrat in ihrem Humankapital unterscheiden und somit durch Geschlechterdiversität die Voraussetzung für Wissens- und Fähigkeitenvielfalt gegeben ist. Hierzu wurden die Lebensläufe von 264 Frauen und Männern in Aufsichtsräten der HDAX- und SDAX-Unternehmen analysiert. Die Ergebnisse zeigen, dass Frauen und Männer im Aufsichtsrat Unterschiede in Bezug auf ihre Studienabschlüsse, ihre Berufserfahrung, die Anzahl weiterer Aufsichtsratsmandate, die Art der Berufung, ihre Auslandserfahrung und die Anzahl ihrer Kinder aufweisen. Keine Unterschiede konnten hinsichtlich der Zugehörigkeit zur Eigentümerfamilie nachgewiesen werden. Daraus lässt sich schlussfolgern, dass Frauen im Aufsichtsrat das Ressourcenbündel an Fähigkeiten und Wissen erweitern. Mit diesem Ergebnis leistet die Studie einen wichtigen Beitrag zur Corporate Governance Forschung. Ferner leistet die Studie einen Beitrag zur Humankapitaltheorie, indem bislang vernachlässigte Humankapitalkriterien untersucht werden und schafft eine Basis für fundierte Diskussionen zum Thema Frauen in Führungspositionen.
    • Samenwerking in de zorgsector

      Krols, Krist'l; Van Steendam, Tom (Zorgmagazine, 2013)
      The present study aims to unravel the relationship between competency development, employability and career success. To do so, we tested a model wherein associations between employee participation in competency development initiatives, perceived support for competency development, self-perceived employability, and two indicators of subjective career success (i.e. career satisfaction and perceived marketability) have been specified. A survey was conducted among a sample of 561 employees of a large financial services organization. The results support the idea that employee participation in competency development initiatives as well as perceived support for competency development is positively associated with workers' perceptions of employability. Moreover, self-perceived employability appeared to be positively related with career satisfaction and perceived marketability. A full mediation effect was found for the relationship between participation in competency development initiatives and both career satisfaction and perceived marketability, while a partial mediation effect was found in case perceived support for competency development was the predictor variable. The implications of our findings for understanding the process through which individuals and organizations can affect subjective career success are discussed.
    • The sandwich game: Founder-CEOs and forecasting as impression management

      Collewaert, Veroniek; Vanacker, Tom; Anseel, Frederik; Bourgois, Dries (Journal of Business Venturing, 2021)
      Drawing on impression management and social exchange theory, we examine the use of positively biased forecasts by (non-)founder-CEOs as an impression management tactic vis-à-vis their existing investors. Contrary to their non-founder counterparts, founder-CEOs identify more with the venture they founded and, therefore, experience greater instrumental and affective concerns about the long-term relationship with their investors. Consequently, we hypothesize that founder-CEOs will strategically provide less positively biased forecasts to their investors than non-founder-CEOs. Using two independent samples with revenue forecasts reported to different venture capital investors and a causal chain scenario study consisting of two experiments, we find consistent support for our hypothesis. Overall, this study provides new insights into the use of forecasts as a post-investment impression management tactic by distinct types of CEOs in entrepreneurial ventures.

    • Scheduling of unrelated parallel machines with limited server availability on multiple production locations: a case study in knitted frabrics

      Kerkhove, Louis-Philippe; Vanhoucke, Mario (International Journal of Production Research, 2014)
      This paper studies a complex variation of the parallel machine scheduling (PMS) problem, as encountered at a Belgian producer of knitted fabrics. The aim is to assign N J jobs to N M unrelated parallel machines, minimising a weighted combination of job lateness and tardiness. Jobs are assigned specific release, and due dates and changeover times are sequence dependent. Current literature is extended by including geographically dispersed production locations, which influence job due dates and objective function coefficients. Furthermore, the changeover interference due to limited availability of technicians is also studied in this paper. The scheduling problem is solved using a hybrid meta-heuristic, which combines elements from simulated annealing and genetic algorithms. This hybrid meta-heuristic is capable of solving real-scale scheduling problems of up to 750 jobs, 75 machines and 10 production locations within reasonable computation time. This hybrid scheduling procedure is extended with heuristic dispatching rules capable of reducing the impact of changeover interference by 23% on average compared to the random scenario, for the case where a single technician is expected to serve up to 12 machines.

    • Scheduling operating rooms: Achievements, challenges and pitfalls

      Samudra, Michael; Van Riet, Carla; Demeulemeester, Erik; Cardoen, Brecht; Vansteenkiste, Nancy; Rademakers, Frank (Journal of Scheduling, 2016)
      In hospitals, the operating room (OR) is a particularly expensive facility and thus efficient scheduling is imperative. This can be greatly supported by using advanced methods that are discussed in the academic literature. In order to help researchers and practitioners to select new relevant articles, we classify the recent OR planning and scheduling literature into tables regarding patient type, used performance measures, decisions made, OR up- and downstream facilities, uncertainty, research methodology and testing phase. Based on these classifications, we identify trends and promising topics. Additionally, we recognize three common pitfalls that hamper the adoption of research results by stakeholders: the lack of a clear choice of authors on whether to target researchers (contributing advanced methods) or practitioners (providing managerial insights), the use of ill-fitted performance measures in models and the failure to understandably report on the hospital setting and method-related assumptions. We provide specific guidelines that help to avoid these pitfalls. First, we show how to build up an article based on the choice of the target group (i.e., researchers or practitioners). Making a clear distinction between target groups impacts the problem setting, the research task, the reported findings, and the conclusions. Second, we discuss points that need to be considered by researchers when deciding on the used performance measures. Third, we list the assumptions that need to be included in articles in order to enable readers to decide whether the presented research is relevant to them.

    • Science or graduates: How do firms benefit from the proximity of universities?

      Leten, Bart; Landoni, Paolo; Van Looy, Bart (Research Policy, 2014)
      This paper examines the impact of universities on the technological performance of adjacent firms. We extend existing research by jointly analyzing, and comparing, the effects of education (graduates) and scientific research (publications) activities of universities on firms’ technological performance. Adopting the knowledge production framework, our study is conducted at the level of 101 Italian territorial areas (provinces) and four industries. Overall, fixed-effect panel data models reveal a positive effect of both university graduates and scientific publications on the technological performance of firms. At the same time, considerable industry differences are observed. While the provision of university graduates positively affects firm performance in all industries under study, additional effects for scientific research are only observed in electrical and pharmaceutical industries that are science-intensive and where the scientific knowledge base is changing rapidly over time. The observation that spillovers from academia into the industrial texture of provinces rely on education and research in an industry-specific manner is relevant to the design of appropriate research and innovation policies.

      Abraham, Filip; Brock, E. (Applied Economics, 2003)
      The impact of trade and technology in the European case is assessed. A framework is developed which incorporates employment effects of (i) export expansion (ii) import competition and (iii) labour-saving productivity improvements. In this context, evidence is found for the hypothesis that international trade induces adjustments in technology.
