Life Cycle Cost Analysis of Different Vehicle Technologies in Singapore

Estimation of cost efficiency for firms in different technologies using data envelopment analysis

Data envelopment analysis (DEA) is a method for evaluating the relative efficiency of a set of firms in a production process. Estimation of cost efficiency is one of the branches of performance evaluation. Cost efficiency evaluates the ability of producing current output with minimum available cost. Now let's assume that there are several groups of firms that operate separately and have differe...

Determination of Optimum Insulation Thickness for Building Walls in Iran Using Life Cycle Cost Analysis

Air-Conditioning (AC) systems are responsible for a considerable portion of the energy consumption in buildings located in high cooling load requiring regions of Iran. In addition, the heat flow through the buildingschr('39') external walls plays a major role in cooling load estimations for the countrychr('39')s hot regions. Therefore, application of insulation materials in external walls has g...

Sensitivity Analysis of Life Cycle Cost Calculation

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...
