    • The impact of internal corporate social responsibility on organizational commitment: evidence from Vietnamese service firms

      Thang, Nguyen Ngoc; Fassin, Yves (Journal of Asia-Pacific Business, 2017)
      This study examines the relationship between internal corporate social responsibility (CSR) and organizational commitment in the service sector in Vietnam. Results from a survey of 256 employees indicate that internal CSR has a positive and significant correlation with organizational commitment. More specifically, labor relations, health and safety, and training and education had a significant effect on organizational commitment whereas work–life balance and social dialogue have no significant association with organizational commitment. The authors also provide implications, limitations, and recommendations for future research.
    • The conceptual foundations of well-being in the service ecosystem

      Lemke, Fred; Hamdan, Qusay; Jafari, Aliakbar (2021)
      There is an increasing recognition of the impact of well-being on multiple stakeholders in the society. This stresses the need to further explore this seminal field of science(Carrington, Zwick, & Neville, 2016; Kilbourne, Dorsch, & Thyroff, 2018; Mittelstaedt, Shultz, Kilbourne, & Peterson, 2014).Thus, in order to formulate a ‘common ground’ for pursuing theory and practice, we have to consider the different perspectives of all stakeholders in the service ecosystem; well-being can then be realized as a value in a co-creative manner (Domegan, Collins, Stead, McHugh, & Hughes, 2013; Guo, Arnould, Gruen, & Tang, 2013; Gurrieri, Previte, & Brace-Govan, 2013). Traditional service marketing approaches neglect the common trade-offs between the longterm well-being of consumers and their short-term wants. Services need to transcend in the delivery of the former aspect – creating well-being – and this, more efficiently and effectively than competitors. This will be the competitive advantage of the future, which the literature agrees on (Kotler, Roberto, & Lee, 2002; Lee & Sirgy, 2004; Sirgy & Lee, 2008). Thus, there is a necessity to further understand service strategies that enhance the co-creation and improvement of well-being. Well-being is a very broad church with lots of different flavours and shades(Burroughs & Rindfleisch, 2002; Kilbourne et al., 2018; Nolan & Varey, 2014). As a result, we lack a holistic understanding of the concept and how it may relate to different stakeholders in the service ecosystem. This creates a gap in knowledge that hinders the improvement of the highly important field. Developing a holistic view requires a better understanding of the concept by piecing together the scattered literature. Given the complexity of the topic, we embark on a systematic review of the existing literature in order to formulate the lacking definition of wellbeing in the service ecosystem. Using multiple techniques (solo coding, inter-coder reliability test, Delphi panel test and grounded theory), we analyze and synthesize the multi-disciplinary literature on well-being. We identify and update the existing conceptualizations of the dimensions of well-being, while identifying the various stakeholders interacting within different environment in the service ecosystem. We map these stakeholders and environments against the dimensions of well-being, which – in conjunction – formulate the definition of overall wellbeing that is applicable in a multi-stakeholders in the service ecosystem. We, furthermore, take a considerable step towards fully understanding the mechanisms of well-being co-creation by exploring the interactions of stakeholders and the interrelations among the well-being dimensions. The study offers a broad spectrum of implications for practitioners as well as an agenda for future research directions.
    • The welfare and price effects of sector coupling with power-to-gas

      Roach, Martin; Meeus, Leonardo (2021)
      Electricity markets with high installed capacities of Variable Renewable Energy Sources (VRES) experience periods of supply and demand mismatch, resulting in near-zero and even negative prices, or energy spilling due to surplus. The participation of emerging Power-to-X solutions in a sector coupling paradigm, such as Power-to-Gas (PTG), has been envisioned to provide a source of demand flexibility to the power sector and decarbonize the gas sector. We advance a long-run equilibrium model to study the PTG investment decision from the point of view of a perfectly competitive electricity and gas system where each sector's market is cleared separately but coupled by PTG. Under scenarios combining PTG technology costs and electricity RES targets, we study whether or not there is a convergence in the optimal deployment of PTG capacity and what is the welfare distribution across both sectors. We observe that PTG can play an important price-setting role in the electricity market, but PTG revenues from arbitrage opportunities erodes as more PTG capacity is installed. We find that the electricity and gas sector have aligned incentives to cooperate around PTG, and instead find an issue of misaligned incentives related to the PTG actor. Although not the focus of our analysis, in some scenarios we find that the welfare optimal PTG capacity results in a loss for the PTG actor, which reveals some intuition that subsidizing PTG can make sense to reduce the cost of RES subsidies. Sensitivity analyses are conducted to contextualize these findings for system specificities.
    • Strategic behaviour in flexibility markets: New games and sequencing options

      Beckstedde, Ellen; Meeus, Leonardo; Delarue, Erik (2021)
      Distribution system operators are expected to procure flexibility when it is cheaper than expanding their distribution grid. How to integrate these flexibility markets in the existing sequence of electricity markets is an important open issue in the evolution of electricity markets in Europe. In this paper, we investigate four market sequencing options: (1) the nodal wholesale market that includes network constraints(WNC); (2) the zonal wholesale market without network constraints followed by an integrated redispatch market to remedy the network congestion at transmission and distribution level created by the wholesale market in a coordinated way (WIR); (3) the zonal wholesale market followed by separate flexibility, redispatch and balancing markets in that order, which implies that congestion at distribution level is treated before congestion at transmission level (WFRB); and (4) the zonal wholesale market followed by separate redispatch, flexibility and balancing markets in that alternative order, which implies that congestion at transmission level is managed before congestion at distribution level (WRFB). We analyse how changing the market sequence can impact the strategic behaviour of flexibility providers, here represented by a Balancing Responsible Party (BRP). We introduce a bi-level model in which the strategic BRP in the upper level acts as a first mover that anticipates the effect of its offers on the market outcome of the lower-level optimization problems. In analogy with the inc-dec game triggered by redispatch markets, we find that flexibility markets can trigger new games. These games will be difficult to detect by regulators as they can be performed by relatively small players. We observe that the WNC market design clearly outperforms the other sequencing options, but there is no clear second best among the alternatives WIR, WFRB, and WRFB.

    • Brand religions: Shed a new light on today's marketing beliefs

      Pallini, K.; Schillewaert, Niels; Goedertier, Frank (2020)
      Since the early days of business, marketing gurus have preached their beliefs on how to build strong brands. These theories and models have been translated into numerous books to provide a clear framework for marketers on what to aim for and how to grow their brand. But in this abundance of models and theories, marketers might find themselves lost in translation.
    • How employees are proactive in strategic behaviors

      Pfisterer, Matthias; De Stobbeleir, Katleen (2021)
      In today’s world of work, employees do not just let change happen to them, instead, they proactively shape their work, as well as their organization and its fit with the environment. Research shows that proactivity may be beneficial to the individual, the team and the organization. However, despite the importance of proactivity in today’s organizations, research has predominantly focused on employees’ proactivity in shaping their internal work environment, by for example exploring how employees can expand the boundaries of their own roles. When confronted with an unpredictable and rapidly changing external environment, however, employees also need to proactively detect and shape opportunities in their external environment. In this doctoral research proposal, we therefore shift focus from internally to externally oriented proactivity, i.e., proactive strategic behavior, to (1) conceptualize the construct of proactive strategic behavior; and (2) develop the nomological network of the concept of proactive strategic behaviors by testing the antecedents and the consequences of proactive strategic behavior.
    • Project recovery: Project failures and how to get rid of them

      De Bruyne, Marie-Julie; Moens, Eva; Vanhoucke, Mario (The Journal of Modern Project Management, 2021)
      Since the 1960s, project success has been receiving much interest from both academics and practitioners. Despite these efforts, project failure is still a recurring and prevalent phenomenon. In both peer-reviewed and non-peer-reviewed project management literature, a great deal of studies generates lists of success factors and failure causes. Few studies, however,investigate concrete recovery strategies to bring failing projects back on track. The present article, therefore, draws upon the literature on critical success factors and project recovery frameworks to construct an eight-step action plan that helps in recovering from project failure. The recovery action plan was awarded the University Contest by PMI Belgium in 2019.
    • Essential skills for data-driven project management: A classroom teaching experiment

      Servranckx, Tom; Vanhoucke, Mario (The Journal of Modern Project Management, 2021)
      We investigate the performance of students in a Data-driven Project Management course module that consists of several realistic case studies derived from the book “The data-driven project manager: A statistical battle against project obstacles” (Vanhoucke 2018). Based on case study evaluations, we monitor the students’ level for various technical and non-technical skills. We identify and classify seven project management skills in management literature and, subsequently, we statistically investigate the link between these skills and the student performance during the course module. Also, a model to incorporate these skills in the Dynamic Scheduling framework is proposed and validated using Structural Equation Modeling. The results indicate that planning is key for good risk analysis and project control, and show that both types of skills are important for successful project management.
    • Deep reinforcement learning for inventory control: a Roadmap

      Boute, Robert; Gijsbrechts, Joren; van Jaarsveld, Willem; Vanvuchelen, Nathalie (European Journal of Operational Research, 2021)
      Deep reinforcement learning (DRL) has shown great potential for sequential decision-making, including early developments in inventory control. Yet, the abundance of choices that come with designing a DRL algo-rithm, combined with the intense computational effort to tune and evaluate each choice, may hamper their application in practice. This paper describes the key design choices of DRL algorithms to facilitate their implementation in inventory control. We also shed light on possible future research avenues that may elevate the current state-of-the-art of DRL applications for inventory control and broaden their scope by leveraging and improving on the structural policy insights within inventory research. Our discussion and roadmap may also spur future research in other domains within operations management.
    • The impact of ceo future focus and long-term incentives on strategic flexibility: Towards person-pay congruence

      De Ruyck, Bettina; Peeters, Carine; Baeten, Xavier; Fehre, Kerstin (2021)
      Strategic flexibility enables organisations to adapt to changing circumstances in a proactive or reactive manner. Although several studies show that it increases company performance, more research on the drivers and barriers to strategic flexibility is needed. In response to that call, we focus on the CEO who plays a crucial role in shaping and implementing the strategy of the organisation. One line of research established in the strategic flexibility literature studies CEO cognition to explain how CEOs differ in the extent to which they build strategically flexible organisations. Accordingly, we put forward CEO future focus as a relevant antecedent of strategic flexibility. However, we argue that this personal trait should be studied in tandem with CEO compensation, as it is their combination that determines the CEO’s strategic choices. The main objective of this paper is to understand how person-pay congruence can be obtained in the best interest of strategic flexibility by integrating CEO compensation and the upper echelons perspective. We argue that a stronger CEO future focus and high long-term incentives both increase strategic flexibility. This analysis will enable us to answer the question on what matters most: person or pay? Second, we investigate whether the person-pay interactions between CEO future focus and long-term incentives are synergistic, additive or buffering in nature. We will test our hypotheses with a panel dataset of the 600 largest listed European firms for the period 2014-2019.
    • Using earned value management and schedule risk analysis with resource constraints for project control

      Song, Jie; Martens, Annelies; Vanhoucke, Mario (European Journal of Operational Research, 2021)
      The main goal of project control is to measure the actual project progress such that the deviations from the plan can be identified and corrective actions can be taken to bring the project back on track. However, in resource-constrained projects, disrupted activities affect their successors due to precedence relations and the other activities due to resource constraints, both of which will result in deviations during project progress. Since the project control approaches solely focus on the deviations based on the network analysis, they do not accurately reflect the progress of resource-constrained projects. This paper extends project control approaches for resource-constrained projects to measure and evaluate whether the project progress is acceptable. Moreover, we design three scenarios considering possible resource conflicts to take corrective actions when needed. In the computational experiment, this project control process is applied to a large set of projects with different characteristics and further validated on real-life project data. The results show that the proposed scenarios and different project control approaches are efficient and reliable, but their use depends on project network structure and resource scarceness.

    • Generalized multi-scale stochastic reservoir Opportunity Index for enhanced well placement optimization under uncertainty in green and brownfields

      Vaseghi, Forough; Ahmadi, Mohammad; Sharifi, Mohammad; Vanhoucke, Mario (Oil & Gas Science and Technology, 2021)
      Well placement planning is one of the challenging issues in any field development plan. Reservoir engineers always confront the problem that which point of the field should be drilled to achieve the highest recovery factor and/or maximum sweep efficiency. In this paper, we use Reservoir Opportunity Index (ROI) as a spatial measure of productivity potential for greenfields, which hybridizes the reservoir static properties, and for brownfields, ROI is replaced by Dynamic Measure (DM), which takes into account the current dynamic properties in addition to static properties. The purpose of using these criteria is to diminish the search region of optimization algorithms and as a consequence, reduce the computational time and cost of optimization, which are the main challenges in well placement optimization problems. However, considering the significant subsurface uncertainty, a probabilistic definition of ROI (SROI) or DM (SDM) is needed, since there exists an infinite number of possible distribution maps of static and/or dynamic properties. To build SROI or SDM maps, the k-means clustering technique is used to extract a limited number of characteristic realizations that can reasonably span the uncertainties. In addition, to determine the optimum number of clustered realizations, Higher-Order Singular Value Decomposition (HOSVD) method is applied which can also compress the data for large models in a lower-dimensional space. Additionally, we introduce the multiscale spatial density of ROI or DM (D2ROI and D2DM), which can distinguish between regions of high SROI (or SDM) in arbitrary neighborhood windows from the local SROI (or SDM) maxima with low values in the vicinity. Generally, we develop and implement a new systematic approach for well placement optimization for both green and brownfields on a synthetic reservoir model. This approach relies on the utilization of multi-scale maps of SROI and SDM to improve the initial guess for optimization algorithm. Narrowing down the search region for optimization algorithm can substantially speed up the convergence and hence the computational cost would be reduced by a factor of 4.
