In this study, the application of Bayes networks and fault tree analysis in reliability estimation have been investigated. Fault tree analysis is one of the most widely used methods for estimating reliability. In recent years, a method called "Bayes Network" has been used, which is a dynamic method, and information about the probable failure of the system components will be updated according to...

web usage mining (wum) is the automatic discovering of hidden informationof user access pattern from the web log data. frequent pattern discovery is one ofthe main techniques in wum that can be used to implement recommender systems,forecast user`s navigational behaviour, and personalize web sites. many algorithmshave been suggested on obtaining frequent user navigation patterns. this paperprese...

In this paper we are to present a practical application of Axiomatic Design (AD) methodology, as a roadmap to lean production, in redesigning a car body assembly line. Axiomatic Design theory provides a framework to simplify the whole problem. According to the AD principles, a hierarchical structure has been developed. The developed structure originated in lean manufacturing principles and exis...

Although ontologies technology has been used in a considerable amount of knowledge management projects, its application has been limited to the definition of a common organizational language. In this paper we present in detail the ontology processes that are related to its application in knowledge management contexts and propose a new way to incorporate ontologies in knowledge management system...

One of the key problems in the study of multiagent systems in which the agents exhibit continuous behavior is the automatic recognition and analysis of intentional activities based on observable behavior. Such an automated analysis requires software systems to structure continuous motions into episodes that are meaningful in the respective application domain, to acquire and maintain models of a...

We propose a method of automatic generation of application specific operating systems (OS’s) and automatic targeting of application software. OS generation starts from a very small but yet flexible OS kernel. OS services, which are specific to the application and deduced from dependency between services, are added to the kernel to construct the whole OS. Communication and synchronization functi...
