  • A heuristic procedure to solve the project staffing problem with discrete time/resource trade-offs and personnel scheduling constraints

    Van Den Eeckhout, Mick; Maenhout, Broos; Vanhoucke, Mario (Pergamon Press, 2019)
    Highlights • Project staffing with discrete time/resource trade-offs and calendar constraints. • An iterated local search procedure is proposed. • Different problem decomposition techniques are applied. Abstract When scheduling projects under resource constraints, assumptions are typically made with respect to the resource availability and activities are planned each with its own duration and resource requirements. In resource scheduling, important assumptions are made with respect to the staffing requirements. Both problems are typically solved in a sequential manner leading to a suboptimal outcome. We integrate these two interrelated scheduling problems to determine the optimal personnel budget that minimises the overall cost. Integrating these problems increases the scheduling flexibility, which improves the overall performance. In addition, we consider some resource demand flexibility in this research as an activity can be performed in multiple modes. In this paper, we present an iterated local search procedure for the integrated multi-mode project scheduling and personnel staffing problem. Detailed computational experiments are presented to evaluate different decomposition heuristics and comparison is made with alternative optimisation techniques.

  • A better way to share the gains of collaborative shipping

    Boute, Robert; Van Steendam, Tom (Peerless Media, 2018)
    Collaborative shipping typically leads to cost savings. However, it's not always easy to determine each partner's contribution to the gains and to share them accordingly. An industry-oriented method has been tested in a set of pilots and promises to be fair, transparent and not overly complex.
  • Digital probes as opening possibilities of generativity

    Jarvenpaa, Sirkka; Standaert, Willem (Association for Information Systems, 2018)
    The information systems research on generativity promises unprompted, innovative inputs from uncoordinated audiences, whose participation with heterogeneous technological resources generates diverse outputs and opens new possibilities. The question is how to perpetuate the openness on which the outputs of generativity rely. We advance, as a potential mechanism of generativity, the concept of digital probes, which leverage human and technological resources in hybrid digital and physical environments. The aesthetically rich probes challenge values, identities, and practices, cultivating emotional tensions that can reveal previously unexplored and unimagined possibilities, resulting in novel ideas, thoughts, and expressions. The new possibilities reveal what is hidden; reconfigure practices; cross-appropriate technological and social resources; and thereby further expand what can be experienced, viewed, and imagined. Further, the new possibilities draw new actors that again view things differently and seek different experiences, thus fueling emotional tensions that in turn open new possibilities, without settling them. We illustrate digital probes and their effects at Formula E. Formula E is a new motorsports venture that leveraged eSports, social media, crowdsourcing, and driverless cars in digital probes to reveal and examine previously unimagined possibilities of what the world of motorsport could be in the digital era. We end by exploring future research directions.
  • Relocation to get venture capital: a Resource dependence perspective (Published Online)

    De Prijcker, Sofie; Manigart, Sophie; Collewaert, Veroniek; Vanacker, Tom (Sage, 2017)
    Using a resource dependence perspective, we theorize and show that non-venture-capital-backed ventures founded in U.S. states with a lower availability of venture capital (VC) are more likely to relocate to California (CA) or Massachusetts (MA)—the two VC-richest states—compared to ventures founded in states with a greater availability of VC. Moreover, controlling for self-selection, ventures that relocate to CA or MA subsequently have a greater probability of attracting initial VC compared to ventures that stay in their home state. We discuss the implications for theory, future research, and practice.
  • Combining EDM and EVM a proposal simplification for project time and cost management

    De Andrade, Paulo André; Vanhoucke, Mario (Mundo Press, 2017)
    Earned value management (EVM), a technique mainly used to manage project cost, was developed during the second half of the twentieth century by an agency of the USA government. It was enriched, at the beginning of the current century, with an extension named earned schedule (ES) (Lipke, 2003), which added to EVM the capability to manage the project schedule. In 2014, earned duration management (EDM), a novel, and monetary value free technique for project schedule management, was proposed by Khamooshi and Golafshani (2014). Earned duration (ED), the project schedule indicator from EDM uses only activity dates and durations from EVM, and aims at replacing ES. By not using cost as a proxy for time, ED overcomes one of the most criticized aspect of ES. This paper intends to (i) compare ED with ES to learn some fundamental lessons, (ii) propose the combination of ED and planned value (PV) from EVM to produce an EDM-based project-level earned value (EVd), and (iii) assess the adequacy of EVd as an alternative to earned value (EV) from EVM in project time and cost management. The comparison between the project real cost and both EVM and EDM-based independent estimates at completion, on a set of real projects, was the vehicle for assessing the adequacy of EVd as a viable alternative to EV. Workload avoidance by replacing activities earned value calculations with the simpler and more consistent determination of the activities earned durations, and the enhanced visibility of potential schedule problems caused by lower cost/duration ratio activities, are benefits that EVd offers to project managers.

  • Een eenvoudig raamwerk voor IT-strategievorming in een lokaal bestuur

    Van den Bergh, Joachim; Viaene, Stijn (Vlaamse Vereniging voor Bestuur en Beleid vzw in samenwerking met uitgeverij die Keure, 2018)
    Vele lokale besturen in Vlaanderen kampen met een lage IT-maturiteit, gebrekkige of onbestaande IT-strategieën en beperkte affiniteit van de beleidsvoerders met digitale technologieën met een hoge ontwikkelingssnelheid. Plaats deze vaststelling in de context van schaarse middelen en een verregaande digitaliseringsnood en ambitie van de overheid en de uitdaging voor (in het bijzonder kleine en middelgrote) besturen wordt tastbaar. Een aantal lokale besturen dreigt vast te lopen in het reactief en ad hoc aanpakken van hoogdringende problemen. Het Provinciaal Intern Verzelfstandigd Agentschap (piva) eGOV ontwikkelde een nieuwe dienstverlening voor de steden en gemeenten in de provincie Oost-Vlaanderen om de achterstand om te buigen door middel van een eenvoudige aanpak om een lokale IT-strategie te formuleren. Concreet biedt de nieuwe dienstverlening een antwoord op de basisuitdaging voor elk lokaal bestuur om keuzes te maken voor IT, met digitale transformatie van de overheid als context. De aanleiding was het nieuwe aanbod van piva eGov (deels gefinancierd door VVSG) als opvolgingstraject voor die besturen die zwak tot matig scoorden in de I-monitorbevraging (Vlaamse IT audit). Piva eGov heeft dit aangegrepen om een nieuwe dienstverlening uit te bouwen, met een nieuwe manier van werken voor zichzelf en haar klanten. De doelstelling was om via een gefaciliteerd proces strategische en operationele keuzes voor IT in een lokaal bestuur te faciliteren, met IT en business op gelijke voet. Het proces werd uitgebouwd in een vorm van Action-Design Research (ADR) (SEIN et al. 2011), dit wil zeggen parallel met de uitvoering door piva eGov, en is met succes toegepast bij vier pilootbesturen. In dit artikel presenteren we de manier van werken, de resultaten en de voornaamste leerpunten voor overheden op het regionale, provinciale en lokale niveau, met het oog op het haalbaar maken van IT-strategievorming in lokale besturen.
  • Systemic risk in the US: Interconnectedness as a circuit breaker

    Dungey, Mardi; Luciani, Matteo; Veredas, David (Elsevier, 2018)
    We measure systemic risk via the interconnections between the risks facing both financial and real economy firms. SIFIs are ranked by building on the Google PageRank algorithm for finding closest connections. For a panel of over 500 US firms over 2003–2011 we find evidence that intervention programs (such as TARP) act as circuit breakers in crisis propagation. The curve formed by the plot of firm average systemic risk against its variability clearly separates financial firms into three groups: (i) the consistently systemically risky (ii) those displaying the potential to become risky and (iii) those of little concern for macro-prudential regulators.
  • Equity crowdfunding, shareholder structures, and firm performance

    Walthoff-Borm, Xavier; Vanacker, Tom; Collewaert, Veroniek (Wiley, 2018)
    Research question/issue: This paper provides a first‐time glimpse into the postcampaign financial and innovative performance of equity‐crowdfunded (ECF) and matched nonequity‐crowdfunded (NECF) firms. We further investigate how direct and nominee shareholder structures in ECF firms are associated with firm performance. Research findings/insights: We find that ECF firms have 8.5 times higher failure rates than matched NECF firms. However, 3.4 times more ECF firms have patent applications than matched NECF firms. Within the group of ECF firms, we find that ECF firms financed through a nominee structure make smaller losses, whereas ECF firms financed through a direct shareholder structure have more new patent applications, including foreign patent applications. Theoretical/academic implications: Our findings suggest that there are important adverse selection issues on equity crowdfunding platforms, although these platforms also serve as a catalyst for innovative activities. Moreover, our findings suggest that there is a more complex relationship between dispersed versus concentrated crowd shareholders and firm performance than currently assumed in the literature. Practitioner/policy implications: For policy makers and crowdfunding platforms, investor protection against adverse selection will be important to ensure the sustainability of equity crowdfunding markets. For entrepreneurs and crowd investors, our study highlights how equity crowdfunding and the adopted shareholder structure relate to short‐term firm performance.
  • Forecasting spare part demand with installed base information: a Review (Accepted)

    Van der Auweraert, Sarah; Boute, Robert; Syntetos, Aris (Elsevier, 2018)
    The classical spare part demand forecasting literature studies methods to forecast intermittent demand. The majority of these methods do not consider the underlying demand generating factors. Demand for spare parts originates from the part replacements of the installed base of machines, which are either done preventively or upon breakdown of the part. This information from service operations, which we refer to as installed base information, can be used to forecast future spare part demand. In this paper we review the literature on the use of such installed base information for spare part demand forecasting to asses (1) what type of installed base information can be useful; (2) how this information can be used to derive forecasts; (3) what is the value of using installed base information to improve forecasting; and (4) what are the limits of the currently existing methods. The latter serve as motivation for future research.
  • Risk governance of financial institutions: The effect of ownership structure and board independence (Published Online)

    Dupire, Marion; Slagmulder, Regine (Elsevier, 2018)
    This paper investigates how the risk governance practices of European financial institutions quantitatively cluster on the corporate governance characteristics of the corporation, particularly ownership structure and board independence. Using hand-collected data on a sample of 54 banks and 33 insurance companies, we find that financial institutions with powerful owners (i.e., those with >20% ownership) have a lower chief risk officer (CRO) presence and lower risk committee presence. In addition, state-controlled institutions and institutions with more independent boards have more independent risk committees.
  • Controlling für innovative junge Unternehmen

    Brettel, Malte; Fehre, Kerstin; Heinemann, Florian (Springer, 2007)
    Der vorliegende Artikel liegt im Forschungsdefizit des „Entrepreneurial Controllings“, d. h. dem Controlling in innovativen jungen Unternehmen begründet. Dieses Forschungsdefizit manifestiert sich neben einer bisher geringen Anzahl an Forschungsarbeiten vornehmlich in offenen forschungstheoretischen Fragen. Unbeantwortet blieben bisher insbesondere die zwei elementaren Fragestellungen nach den controllingrelevanten Merkmalen und infolgedessen nach den Anforderungen an ein Controlling in innovativen jungen Unternehmen. Diesem Forschungsdefizit steht ein hoher Praxisbedarf gegenüber: ein fehlendes Controlling in innovativen jungen Unternehmen zählt zu den Hauptursachen ihres Scheiterns. Unter Anwendung des Rationalitätssicherungsansatzes leistet der vorliegende Artikel einen wesentlichen Beitrag zur Beantwortung dieser Fragestellungen und zur Schließung der Forschungslücke im „Entrepreneurial Controlling“. Hierzu werden zunächst die Besonderheiten innovativer junger Unternehmen...
  • The Disappearing ‘Deutschland AG’ – An analysis of blockholdings in German large caps

    Fehre, Kerstin; Rapp, Marc-Steffen; Schwetzler, Bernhard; Sperrling, Marco (LLC “Consulting Publishing Company “Business Perspectives”, 2011)
    The German corporate governance system changed substantially over the last ten years. Meanwhile, ownership structures of German firms changed significantly. The paper examines the phenomenon of changing ownership structures by studying blockholdings of German large caps between 1997 and 2006. It examines the dynamics of blockholdings by analyzing the evolution of free float and block trades, where at least 5% of voting rights change hands. Two findings emerge. First, the authors find that free float increases from 65% in 1997 to 75% in 2006, mainly caused by German financials and German government entities. Simultaneously, they observe a surprisingly high number of block trades: on average 1.6 block trades per firm from 1997 to 2006. Second, the authors find that particularly individuals and German industrials are guarantors for a stable ownership structure. German financials or German government entities as blockowners increase the free float and the likelihood of block trades. Moreover, block trades are more likely to occur in firms having foreign investors as owners. The findings are of interest with respect to the evolution of the so-called ‘Deutschland AG’ but also with respect to the current anchor shareholder discussion.
  • Förderung von Frauen in Führungspositionen: Bezugsrahmen und empirische Analyse der unternehmerischen Maßnahmen

    Fehre, Kerstin; Lindstädt, Hagen; Picard, Alexander (Springer, 2014)
    Der Beitrag untersucht den Umsetzungsgrad von Maβnahmen zur Förderung von Frauen in Führungspositionen. Mittels einer Umfrage unter den CDA X-Unternehmen sowie kleinen und mittleren Unternehmen (KMU) wird eine Bestandsaufnahme angewendeter Maβnahmen erarbeitet und weiterer Handlungsbedarf identifiziert. Dies stellt die bisher gröβte empirische Untersuchung dieser Art in Deutschland dar. Der Beitrag zeigt, dass Unternehmen mit einer vergleichsweise hohen Repräsentanz von Frauen in Führungspositionen einige der Maβnahmen verstärkt umsetzen, diese jedoch über die gesamte Stichprobe eher unterdurchschnittlich häufig angewendet werden. Es hat sich auf Maβnahmenseite bisher kein Standard etabliert; ein hoher Frauenanteil in Führungspositionen scheint derzeit noch das Ergebnis unternehmensindividueller Gegebenheiten zu sein.
  • Lost in transaction? The transfer effect of strategic consistency

    Fehre, Kerstin; Kronenwett, Daniel; Lindstädt, Hagen; Wolff, Michael (Springer, 2016)
    Prior empirical studies provide evidence that the learning-curve perspective from manufacturing settings is not directly applicable to strategic management settings. In the latter case learning relates to the quality rather than to the quantity of experience. Regarding the antecedents of organizational learning especially, there are still unanswered questions remaining; for example, the questions what kind of experience has a positive effect on performance and what kind of experience is more of a hindrance than a help. This becomes obvious when looking at acquisitions as examples of strategic management decisions. Results of prior empirical studies analyzing the relationship of acquisition experience and acquisition performance have been mixed. By introducing the concept of strategic consistency, we intend to facilitate a better understanding of the kind of experience necessary for organizational learning. Therefore, we measure the concordance and frequency of change in strategic actions. Employing a sample of 379 acquisition series, we find evidence for a positive transfer effect of strategic consistency within series and, therefore, a positive relationship between strategic consistency and acquisition performance.
  • Challenging corporate commitment to CSR: Do CEOs keep talking about corporate social responsibility (CSR) issues in times of the global financial crisis?

    Fehre, Kerstin; Weber, Florian (Emerald, 2016)
    Purpose In times of crisis, the fundamental principles of companies erode, leading to strategy shifts. This paper aims to examine whether corporate social responsibility (CSR) is on management’s agenda in times of crisis, indicating CSR embeddedness into corporate strategy. The focus is on the four pillars of CSR: social, environment, economy and governance. Design/methodology/approach Starting points are competing hypotheses based on shareholder and stakeholder theory. Chief executive officer (CEO) letters to shareholders of German HDAX firms from 2003 to 2012 are analyzed by means of computer-aided text analysis. Findings The authors find that CEOs talk less about CSR in times of crisis, especially about social and governance issues, indicating that CSR is not fully embedded into corporate strategy, and that, in times of crisis, other aspects gain more importance on management’s agenda.
  • Same same, but different: Eine Analyse des Humankapitals weiblicher und männlicher Aufsichtsräte in Deutschland

    Fehre, Kerstin; Spiegelhalder, Rebecca (Springer, 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.
  • DSO-TSO cooperation issues and solutions for distribution grid congestion management

    Hadush, Samson; Meeus, Leonardo (Elsevier, 2018)
    The role of DSOs is evolving due to the increasing penetration of intermittent and distributed energy resources in the distribution system. On the one hand, TSOs are accessing flexibility resources connected to the distribution grid. On the other hand, DSOs are actively managing distribution grid congestion, moving away from the conventional fit and forget approach. As a result, the need for DSO-TSO cooperation has become increasingly important. In this study, we first discuss market and grid operation issues related to different system states and the corresponding congestion management approaches, in the context of the European electricity market design and regulation. Second, we discuss viable solutions that are inspired by inter-TSO cooperation solutions as well as solutions that are being adopted by DSOs. Our findings show that the issues are rather similar both at transmission and distribution level; however, the need for cooperation and the solutions will depend on where structural congestion will occur and which borders will be managed. We also note that cooperation between DSOs as well as between DSOs and microgrids could become more important with the development of local energy markets in the long term.
