MAINTENANCE MANAGEMENT OF COMPLEX INDUSTRIAL SYSTEMS

Abstract

A general discussion about maintenance management and the result from a case study carried out at five energy companies and one pulp and paper industry was first presented. The basis for an understanding of the research area is established and other methods that can be used to cope with this issue are presented. Description of the DLA method (Dynamic Lifetime Analysis) and CBI (Condition Based Index) and the experiences from a minor case study-based evaluation of the DLA are described. Also, the DLA and CBI are put together in a joint methodology. The methodology is also described from in a wider perspective for a reader to gain better understand of the ideas behind the approach. A case study-based evaluation carried out at Forsmark\s nuclear power station and at SCA Graphic of the methodology. The methodology was first evaluated via a case study on a feed water pump system at Forsmark. Lesson learned from that study was then used to develop the methodology and it was then applied to a refiner at SCA Graphics mill in Sundsvall
