The opportunistic replacement problem: theoretical analyses and numerical tests

Almgren, Torgny; Andréasson, Niclas; Patriksson, Michael; … - In: Mathematical Methods of Operations Research 76 (2012) 3, pp. 289-319

We consider a model for determining optimal opportunistic maintenance schedules w.r.t. a maximum replacement interval. This problem generalizes that of Dickman et al. (J Oper Res Soc India 28:165–175, <CitationRef CitationID="CR12">1991</CitationRef>) and is a natural starting point for modelling replacement schedules of more complex...</citationref>
