The objective of this paper is to present a framework developed for assisting railway operators into monitoring and controlling the quality of services provided to their passengers. This framework is based on the estimation of 22 indicators, grouped under six criteria, i.e. itinerary accuracy, system safety, cleanness, passenger comfort, servicing, and passenger information. The valuation of th...

This paper develops a methodology which allows the correlation between the cost which is required for the application of preventive and mitigation measures dealing with accidents which occur within a railway system and the improvement of the level of safety as a result from their implementation. The safety level is expressed either quantitatively, by the decrease of “fatality risk” indicator...

OBJECTIVE The aim of this study was to examine individual markers of resilience and obtain quantitative insights into the understanding and the implications of variation and expertise levels in train traffic operators' goals and strategic mental models and their impact on performance. BACKGROUND The Dutch railways are one of the world's most heavy utilized railway networks and have been ident...

PURPOSE To determine how productivity- and finance-related indicators are used by radiology departments to evaluate departmental performance. MATERIALS AND METHODS The study met the criteria to be exempt from institutional review board approval. All subjects were informed of the purpose of the study and that their questionnaire responses would be kept confidential. For the study, a survey was...

North American railways have traditionally practiced tonnage-based dispatching, running trains only when they have enough freight. As a result, their customer service and their use of crews, fixed assets, locomotives, and railcars are poor. Canadian Pacific Railway is using new decision-support tools developed in-house and by MultiModal Applied Systems to create a scheduled railway. These tools...

Organizations that maintain and evolve software would benefit from measuring productivity in an easy and reliable way. This could allow them to determine if new or improved practices are needed, and to evaluate improvement efforts. We propose and evaluate indicators of productivity trends that are based on the premise that productivity during software evolution is closely related to the effort ...

Human capital is considered as a strategic resource among the main resources of any organization and an important factor in producing and presenting services to the society. Improving the productivity of human capital is the main cause of the improvement of productivity in organizations. Management of human capital development, focuses on the quantitative models and technics to test the product...

With the progress of power electronic devices in electric railway, harmonics in power systems become increasingly of concern. This paper presents a case study on harmonics in a traction power supply system. The study was based on measurements realized in an electrical drive station using a data acquisition system and a computer. It was analyzed the main power quality indicators: the power facto...
