Download or read book Understanding Measuring and Improving Daily Management written by Ross Kenneth Kennedy and published by CRC Press. This book was released on 2019-01-15 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding, Measuring, and Improving Daily Management explains the critical parts of a continuous improvement strategy to achieve Operational Excellence and where reactive improvement through effective daily management fits in. In addition, it shows the consequences to your Operational Excellence journey if daily management is not performed well. Reactive improvement develops the capability and discipline within the organization to be able to rapidly recover from an event or incident that stops you from achieving your expected or target performance for the day, shift, or hour and most importantly -- your ability to capture the learning and initiate corrective actions so that the event or incident will not re-occur anywhere across the organization. As such, reactive improvement focuses on improving daily management through your daily review meetings, your information centers supporting the daily review meetings, and your frontline problem-solving root cause analysis capability at all levels. The book introduces the seven elements of reactive improvement that must work in concert for effective daily management and allows the reader to rate their site or department to determine their starting point compared to best practices: 1. Supportive organization structure to support development of your people so they have ownership and accountability for the performance of their area of responsibility; 2. Effective frontline leaders to ensure everyone else in the leadership structure are not working down a level; 3. Appropriate measures with expected targets that are linked to the site’s Key Success Factors for Operations to ensure goal alignment, and are relevant to the area being focused on; 4. Structured daily review meetings to identify opportunities (problems/incidents) and monitor progress of their solution so they don’t happen again; 5. Visual information centers that visually display daily and trending performance along with monitoring of actions to address problems/issues raised; 6. Frontline problem-solving root cause analysis capability across the site; and 7. Rapid sharing of learning capability across shifts, departments, and the organization. The author outlines in detail why each of the seven elements are important to achieving Operational Excellence, and most importantly, how to implement each element supported with many templates and tools.

This book was released on 2008-04-10 with total page 478 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the presentations given during the 9th International Workshop on Railway Noise (IWRN9) which took place in Munich/Feldafing, Germany, on 4th to 8th September 2007. This workshop was organised by the Acoustics and Vibration Department of DB Systemtechnik, the technical engineering office of Deutsche Bahn AG. More than 120 participants from 17 countries followed the invitation to the wo- shop. This great response showed the continuing interest in an important topic of railway technology and offered the opportunity to present the recent results of intense worldwide activities to the international community of railway noise and vibration experts and to share knowledge as well as experience. Because an efficient transportation network is indispensable to handle the general mobility increase and road networks have reached their socio-ecological limits, the railway network is to be strengthened. For example the European Commission has given distinct political signals to get more passengers onto the railways. This policy represents a clear challenge for the next few decades not only for European railway companies: the considerable increase in mobility will lead to a doubling of the railway traffic volume within the next 10 to 20 years. To reduce the environmental impact, the Directive on the Assessment and M- agement of Environmental Noise has been put into force in Europe, aiming at avo- ing, preventing or reducing harmful effects of environmental noise on human health.

Download or read book Residual Stress in Rails written by O. Orringer and published by Springer Science & Business Media. This book was released on 1992-03-31 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rail integrity is a current application of engineering fracture mechanics at a practical level. Although railroad rails have been manufactured and used for more than a century, it is only in the last ten years that the effects of their crack propagation and fracture characteristics have been considered from a rational viewpoint. The J,Jractical objectives are to develop damage tolerance ~delines for rail inspection and to improve the fracture resistance of new rail productiOn. Rail fatigue crack propagation rates and fracture resistance are strongly influenced by residual stresses, which are introduced into the rail both during proouction and in service. Therefore, the rail residual stress field must be well understood before fracture mechanics can be usefully applied to the subject of rail integrity. The three-dintensional character of rail and its stress fields make it essential to apply both experimental and analytical methods in order to twderstand the effects of pro duction and service variables on residual stress and the effects of the stress on fatigue crack propagation and fracture. This volume brings to~ether field observations and experimental stress analysis of railroad rails in the Umted States and Europe. The ongoing search for an efficient and accurate technique is emphasized. A companion volume brings together several analytical investigations, based on advanced compu tational mechanics methods, for correlation of the experimental data as well as eval uation of the effects of residual stress on rail integrity.
