Huseby, Arne Bang; Eide, Kristina A.; Isaksen, Stefan L.; Natvig, Bent; Gåsemyr, Jørund (Research report / Forskningsrapport, 2008)In the present paper we use discrete event simulation in order to analyze a binary monotone system of repairable components. Asymptotic statistical properties of such a system, e.g., the asymptotic system availability and ...

Natvig, Bent; Mørch, Hans W.H. (Research report / Forskningsrapport, 2002)The basic multistate reliability theory was developed in the eighties and the beginning of the nineties, replacing traditional reliability theory where the system and the components are always described as functioning or ...

Natvig, Bent; Gåsemyr, Jørund; Reitan, Trond (Research report / Forskningsrapport, 2010)In the present paper we consider a multistate monotone system of multistate components. Following a Bayesian approach, the ambition is to arrive at the posterior distributions of the system availabilities and unavailabilities ...

Kristiansen, Monica; Winther, Rune; Natvig, Bent (Research report / Forskningsrapport, 2011)Predicting the reliability of software systems based on a component-based approach is inherently difficult, in particular due to failure dependencies between software components. One possible way to assess and include ...

Bitner-Gregersen, Elzbieta M.; Vanem, Erik; Gramstad, Odin; Hørte, Torfinn; Aarnes, Ole Johan; Reistad, Magnar; Breivik, Øyvind; Magnusson, Anne Karin; Natvig, Bent (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)The paper addresses projected changes of wave climate in the North Atlantic and their impact on the safe design of ships, with a particular focus given on associated uncertainties. The Fifth Assessment Report of the ...

Storvik, Bård; Natvig, Bent; Aldrin, Magne T. (Research report / Forskningsrapport, 2001)This survey is intended for estimating several types of copyright volume at different educational institutions in Norway. Using a calibration factor being equal to the ratio of the true number of machine pages taken from ...

Natvig, Bent; Tvete, Ingunn Fride (Research report / Forskningsrapport, 2004)Stochastic earthquake models are often based on a marked point process approach as for instance presented in Vere-Jones (1995). This gives a fine resolution both in space and time making it possible to represent each ...
-
Gåsemyr, Jørund; Natvig, Bent; Sørensen, Erik (Research report / Forskningsrapport, 1999)In this paper we consider the generalized gamma distribution as introduced in Gåsemyr and Natvig (1998). This distribution enters naturally in Bayesian inference in exponential survival models with left censoring. In the ...

Aursnes, Ivar; Tvete, Ingunn Fride; Gåsemyr, Jørund; Natvig, Bent (Research report / Forskningsrapport, 2001)Background: According to published data, the ability to prevent various hypertension related events differs between the various anti-hypertensive drug groups. Although absolute drug effects with similar drugs also differ ...
