    Sammanfattning : The term Software Maintenance was coined in the early 1970s. The subject has significance from several points of view. The costs associated with software maintenance are as a rule considerably higher than what the system cost to develop, which is borne out by many studies conducted in different countries over a period of twenty years.

    Sammanfattning : This thesis describes the role of cost effective maintenance in achieving competitive advantages. It explores by means of a survey which maintenance practices are used, and how maintenance policies are selected in Swedish industries. LÄS MER

  5. 4. On maintenance optimization for offshore wind farms

    Författare :Francois Besnard; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; life cycle cost; optimization; maintenance; maintenance planning; Offshore wind energy; maintenance strategy; maintenance support organization; reliability;

    Sammanfattning : The maintenance cost is known to be an important part of the levelized cost of energy generated by wind parks. Operational costs can be significantly reduced by optimizing decisions for maintenance strategies, maintenance support organization and maintenance planning. LÄS MER

  7. 5. Property Maintenance : Concepts and determinants

    Författare :Henry Muyingo; Hans Lind; Göran Lindahl; KTH; []
    Nyckelord :Housing maintenance; property management; real estate; housing companies;

    Sammanfattning : Introduction Strategic property management aims at balancing the question of how the needed space is to be secured, maintained, increased or disposed of in a cost effective manner under a mixture of decisions and actions. In recent years, the interest in building maintenance has increased as more and more of the housing stock built after the Second World War is in need of major renovation. LÄS MER
