Managing a nuclear power plant (NPP) calls for evaluation and trading off the conflicting objectives of safe operation and economic burden. The reduction of NPP risk is strongly correlated to the reduction of NPP safety systems unavailability. The application of the probabilistic safety assessment in order to reduce safety systems unavailability is one of the prime goals in the nuclear safety a...

Transformation of equipment manufacturers to become providers of industrial services is a trend that involves deep transformation of companies. Equipment manufactures can potentially provide services significantly more efficiently and effectively by utilizing information about their installed base. We aim to recognise decision support functionality and required information contents for a system...

Surveys found that large contractors replace approximately 10% of their equipment fleet units annually in North America. Cost minimization model is a commonly accepted method for equipment replacement which helps to identify these equipment units whose total owning and operating cost reaches their minimum point as candidates for replacement. While the model is conceptually clear with the aim of...

One important issue in using the industrial and manufacturing facilities is to consider their impacts on the environment. Many of these equipment have negative effects on the environment when operated for sometimes. In this research the probabilistic logistic times and the destructive effects for maintenance are studied and appropriate model is suggested and evaluated. The aim of the proposed m...
