• Gaining insight in domestic violence with Emergent Self Organizing Maps

      Poelmans, Jonas; Elzinga, Paul; Viaene, Stijn; Van Hulle, Marc; Dedene, Guido (+) (Expert Systems with Applications, 2009)
      Topographic maps are an appealing exploratory instrument for discovering new knowledge from databases. During the past years, new types of Self Organizing Maps (SOM) were introduced in the literature, including the recent Emergent SOM. The ESOM tool is used here to analyze a large set of police reports describing a wide range of violent incidents that occurred during the year 2007 in the Amsterdam-Amstelland police region (the Netherlands). This article aims to demonstrate that the ESOM tool provides a valuable exploratory instrument for examining unstructured text in police reports. First, it is shown how ESOM was used to discover a range of new features that better distinguish domestic from non-domestic violence cases. Second, it is demonstrated how this resulted in a significant improvement in classification accuracy. Third, the ESOM tool facilitates an in-depth investigation of the nature and scope of domestic violence, which is particularly useful for the domain expert. Interestingly, it was discovered that the definition of domestic violence employed by the management was much broader than the definition employed by police officers. Fourth, the ESOM tool enables an accurate and automated assignment of either a domestic or a non-domestic violence label to unclassified cases. Finally, ESOM is a highly accurate and comprehensible case triage model for detecting and retrieving wrongly classified cases.

    • 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.
    • Genetic algorithms for single machine scheduling problems: a trade-off between intensifications and diversification

      Sels, Veronique; Vanhoucke, Mario (2012)
      This article reviews the literature on attitudes toward change. This narrative review of 58 journal articles published between 1993 and 2007 indicates that there is a need for a more complete typology of attitudes toward change that also fully captures the core essence of this concept. By means of content analysis we first examined the conceptual overlap between the eight attitude-related constructs included in this review and the working definition of attitudes toward change. Second, the concept “attitudes toward change” was described along four major theoretical lenses: (a) nature of change, (b) level of change, (c) positive—negative view on change, and (d) research perspective. This conceptual review not only summarizes the current state of research but also offers a more complete typology of attitudes toward change, and highlights directions for possible future inquiry.

    • German Cooperative Bank Berlin (B): Managing people, customers, and financial results

      Verweire, Kurt; De Grande, Jonathan; Letens, Geert; Slagmulder, Regine (2011)
      This is part of a case series. The GCB Berlin cases describe a strategic transformation process of a German bank. Over a period of 3 years, GCB Berlin has transformed into a customer-intimate financial institution. The management team of the company used Strategy Mapping, the Balanced Scorecard, and a new sales-and-service approach as transformation tools to get the entire organization more strategy-focused. The (A) case, 'Bringing German Cooperative Bank Berlin back on track: Can a rural bank thrive in the city?,' sets the scene and describes the challenges Arthur Berthold faced when he entered as a newly appointed director. The (A) case provides more information on the personal background of Arthur Berthold, and on his track record with previous employers. Furthermore, the case describes German Cooperative Bank (GCB) Berlin, a subsidiary of the German Cooperative Banking Group. After working some weeks in this new organization, Arthur detected fundamental financial and cultural problems. He decided to tackle the challenges by launching a Balanced Scorecard project, but was struggling how to do it. Should he opt for a top-down approach, or is a bottom-up approach more appropriate? The case, 'German Cooperative Bank Berlin (B): Managing people, customers, and financial results,' describes the start of the change process at GCB Berlin. The (B) case describes how Arthur Berthold transformed GCB Berlin from an undifferentiated and unprofitable bank into a real customer-oriented, profitable financial institution. The top management team launched two strategy maps, one for the Retail Division and one for the Corporate Division. The (B) case describes how the strategy maps were introduced and what were the effects on the management culture and the operations of the organization. The (B) case also describes a change in the sales-and-service culture within the Retail Division through the introduction of the Cohen Brown program.
