A lifetime optimization methodology for planning the inspection and repair of structures that deteriorate over time is introduced and illustrated through numerical examples. The optimization is based on minimizing the expected total life-cycle cost while maintaining an allowable lifetime reliability for the structure. This method incorporates: (a) the quality of inspection techniques with diffe...

Plant and system operators are looking for reliable products meeting high technical requirements while providing maximum economic benefit throughout the life cycle. Calculating life cycle costs different operating conditions have to be considered to provide reliable decision making assistance. If data for a direct probability measurement may not be available, expert knowledge needs to be consid...

This paper presents a sensitivity analysis of the life cycle cost calculation made in the master thesis “Maintenance management of wind power systems Cost effect analysis of condition monitoring systems” by Julia Nilsson (2006). In that thesis, the possible economical gain of a conditioned monitoring system (CMS) in wind power plants is investigated, by comparison of life cycle costs for differ...

The ability to obtain relevant information in a timely and cost efficient manner is central to the effective performance of most tasks in our society. The widespread availability of computer-based information brokers will provide that ability to large communities by significantly facilitating effective access to the broad range of information that is rapidly becoming available on the Internet. ...

Abstract Geotechnical engineering work contributes to the total environmental impact and monetary cost occurring from construction sector. Decisions made regarding geotechnical aspects have a profound effect on of structure during its life cycle. Life Cycle Assessment (LCA) Cost Analysis (LCCA) are established methods for assessing impacts works. This paper presents results literature review 56...

Black liquor evaporation is generally the most energy intensive unit operation in a pulp and paper manufacturing facility. The black evaporators can represent third or more of total mill steam usage, followed by machine digester. Evaporator economy defined as mass required to evaporate water from (i.e., lb/lb kg/kg.) determined number effects an evaporator train system configuration. Older syst...
