lack of scientific and confirmed researches and expert knowledge about evaluation systems for clinical governance development in iran have made studies on different evaluation systems for clinical governance development a necessity. these studies must provide applied strategies to design criteria of implementing clinical governance for hospital's accreditation. this is a descriptive and compara...

Reliability, availability, maintenance and safety (RAMS) analysis is essential in the evaluation of safety critical systems like nuclear power plants and the railway infrastructure. A widely used methodology within RAMS analysis are fault trees, representing failure propagations throughout a system. We present DFTCalc, a tool-set to conduct quantitative analysis on dynamic fault trees including...

Traditional maintenance planning is based on a constant maintenance interval for equipment life. In order to consider economic aspect for time based preventive maintenance, preventive maintenance is desirable to be scheduled by RCM(ReliabilityCentered Maintenance) evaluation. So, Markov state model is utilized considering a stochastic state in RCM. In this paper, the Markov state model which ca...

Two aspects of the selection and evaluation of software packages are reviewed: the strategy for evaluation and selection, and criteria that might be applied in selection. The evaluation and selection of a software package should be approached as a project. Appropriate strategies for the selection and evaluation of software packages can be based on information systems methodologies. The main sta...

Case Base maintenance can be crucial to CBR system performance. A central current of case base maintenance research focuses on competence-based deletion. Traditionally, deletion is done periodically, pausing CBR system processing to examining the entire case base. However, for streaming data, as often arises in big data contexts, such an approach may be expensive or infeasible. To address this ...

In order to reduce operating costs and increase the operational stability, aviation industry is continuously introducing digital technologies automate state detection of their assets derive maintenance decisions. Thus, many efforts research activities have focused on an early fault prediction system failures. Since has mainly been limited calculation remaining useful lifetimes (RUL) neglected i...

Software maintenance phase is started once a software project has been developed and delivered. After that, any modification to it corresponds to maintenance. Software maintenance involves modifications to keep a software project usable in a changed or a changing environment, to correct discovered faults, and modifications, and to improve performance or maintainability. Software maintenance and...
