A real-life system is usually modeled to be a network with edges and nodes for the performance evaluation. This paper devotes to finding out the optimal two-type component assignment with maximal system reliability, in which the components are separated to be two sets: one assigned to edges and the other set assigned to nodes. Each component should be multistate due to complete failure, partial...

We propose a software toolkit for developing complex web-based user interfaces, incorporating such things as multi-user facilities, virtual environments (VEs), and interface agents. The toolkit is based on a novel software architecture that combines ideas from multi-agent platforms and user interface (UI) architectures. It provides a distributed shared database with publish-subscribe facilities...

Bir bütünlük olarak algılanan ulus-devletler genellikle faklı etnik grupların oluşturduğu bir denge haline karşılık gelmektedir. Kültürel, dini ya da milliyet içerikli farklılık gösterebilen alt gruplar, baskın etninin devlet mekanizmasını idare edebilme yetisi çerçevesinde örtük baskı ortamında varlıklarını sürdürmektedir. Dolayısıyla söz konusu halinin sürdürülebilirliği farklı unsurların dah...

Availability/reliability is a main feature of design and operation of all engineering systems. Recently, availability evaluation of multi-state systems with different structures is at the center of attention due to the wide applications in engineering. In this paper, a dynamic model is developed for the availability assessment of multi-state weighted k-out-of-n systems. Then, in a design optimi...

this paper examines critically the contributions of cournot, jevons and walras as the founders of classical mathematical economics from a methodological standpoint. advances in different economic schools and doctrines in the 19th century produced an environment of multi-dimensionality in economic analysis which was regarded by the pioneers of classical mathematical economists as a chaotic state...

Reliability evaluation of systems composed of non-identical multi-state components is a challenging task due to the highly combinatorial nature of the problem. The outcome is a lack of understanding regarding the reliability behavior of a system when components with different magnitudes of failure probabilities are considered, especially when extra components are added. The present work address...

In the present study, we analyze the multi-channel service system with ordered entryfrom finite-source and finite-storage at each channel. The arrival and service rates are assumedto be state dependent. The steady state probabilities of the system are obtained by usingChapmann-Kolmogorov equations. Some other performance indices viz. utilization of servers,expected number of units in the system...
