• Impacts of supply chain management on company value: benchmarking companies from the fast moving consumer goods industry

  Brandenburg, M. ., & Seuring, S. . (2011). Impacts of supply chain management on company value: benchmarking companies from the fast moving consumer goods industry. Logistics Research, 3(4), 233–248. http://doi.org/10.1007/s12159-011-0056-7

  Abstract

  The research question addressed is to which extent supply chain management (SCM) creates value from cost and working capital. The paper provides an empirical evaluation including insights on important criteria for value creation. In a secondary data analysis, 10 leading fast moving consumer goods (FMCG) companies are benchmarked regarding the value created from cost of goods sold (COGS) and working capital within the time horizon 2003–2008. The study applies benchmarking methodology and a discounted cash flow (DCF) based model for quantifying value contributions. It is shown that SCM is realized in a value-adding way with different emphasis on COGS or working capital. Monetarily working capital components (trade payables, trade receivables) have a high relevance for value creation. Continuous improvements and long lasting developments of value drivers are more appropriate for value creation than alternating improvements and deteriorations. Timing aspects of value driver developments have to be considered for value creation. The value of the paper stems from empirical comparison of value created by working capital and COGS and from evidence of important criteria for value creation. Further analysis based on cost components as well as benchmarking with different or extended content, such as fixed asset performance or cross-industry benchmarking, leave room for future research.

• Informatics in Radiology: Use of a C-Arm Fluoroscopy Simulator to Support Training in Intraoperative Radiography

  Bott, O. ., Dresing, K. ., Wagner, M. ., Raab, B.-W. ., & Teistler, M. . (2011). Informatics in Radiology: Use of a C-Arm Fluoroscopy Simulator to Support Training in Intraoperative Radiography. RadioGraphics, 31, E65-E75. http://doi.org/10.1148/rg.313105125

  Abstract

  Mobile image intensifier systems (C-arms) are used frequently in orthopedic and reconstructive surgery, especially in trauma and emergency settings, but image quality and radiation exposure levels may vary widely, depending on the extent of the C-arm operator s knowledge and experience. Current training programs consist mainly of theoretical instruction in C-arm operation, the physical foundations of radiography, and radiation avoidance, and are largely lacking in hands-on application. A computer-based simulation program such as that tested by the authors may be one way to improve the effectiveness of C-arm training. In computer simulations of various scenarios commonly encountered in the operating room, trainees using the virtX program interact with three-dimensional models to test their knowledge base and improve their skill levels. Radiographs showing the simulated patient anatomy and surgical implants are “reconstructed” from data computed on the basis of the trainee s positioning of models of a C-arm, patient, and table, and are displayed in real time on the desktop monitor. Trainee performance is signaled in real time by color graphics in several control panels and, on completion of the exercise, is compared in detail with the performance of an expert operator. Testing of this computer-based training program in continuing medical education courses for operating room personnel showed an improvement in the overall understanding of underlying principles of intraoperative radiography performed with a C-arm, with resultant higher image quality, lower overall radiation exposure, and greater time efficiency.

  The importance of technology for the medical sector is steadily growing. Potentials for rationalization that can help to overcome the problems of an ageing population exist. So far these expectations could not be fulfilled because some devices lack a sufficient usability concept and do not fulfill the user demands. This chapter will illustrate problems that can arise when developing user-centered and task-oriented “health care applications.” The “medico ergonomics approach” is introduced as a possibility to overcome these problems. The applicability of the developed approach is demonstrated with the help of a case study. Content of this case study is a usability context analysis of a web-based patient record. The case study shows the suitability of the medico ergonomic models to illustrate complex interrelations of patient treatment. Based on these results requirements are defined and task-supporting functions are derived. The models support the development of a “common ground of understanding” between the potential user and the developers of the product. This is a crucial condition for developing integrated and utilizable (software) products and therewith for developing ergonomic working systems.
