    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; point process; renewal process; random environment; coupling; regeneration; failure rate; Poisson embedding; asymptotics; stochastic domination; stochastic monotonicity; renewal process;

    Sammanfattning : This paper deals with a generalization of the class of renewal processes with absolutely continuous life length distribution, obtained by allowing a random environment to modulate the stochastic intensity of the renewal process. The random environment is a birth and death process with a finite state space. LÄS MER

    Sammanfattning : The subject of this thesis concerns pricing the use of transport infrastructure. We are empirically investigating the relationship between railway traffic volumes and infrastructure management costs. More specifically, we are interested in estimating the change in infrastructure management costs from marginal variations in traffic volumes, i.e. LÄS MER
