This note re-visits the rolling-horizon control approach to problem of Markov decision process (MDP) with infinite-horizon discounted expected reward criterion. Distinguished from classical value-iteration approaches, we develop an asynchronous on-line algorithm based on policy iteration integrated a multi-policy improvement method switching. A sequence monotonically improving solutions forecas...

Finite element (FE)model updating technique belongs to the class of inverse problems in classicalmechanics. According to the continuum damage mechanics, damage is represented by a reduction factor of the element bending stiffness. In this study, a global optimizationmethod called ‘Coupled Local Minimizers’ (CLM) is used for updating the finite element model of a complex structure. In CLM, the l...

For FRF based model updating procedures, the selection of updating frequencies and the choice of a damping approach are important factors to obtain reliable updating resuns. This paper discusses the selection of the updating frequencies and shows that damping approaches like proportional, structural or modal damping are not satisfactory for model updating purposes.

Jeffrey updating is a natural extension of Bayesian updating to cases where the evidence is uncertain. But, the resulting degrees of belief appear to be sensitive to the order in which the uncertain evidence is acquired, a rather un-Bayesian looking effect. This order dependence results from the way in which basic Jeffrey updating is usually extended to sequences of updates. The usual extension...
