Akademisk avhandling som med tillstånd av Kungl Tekniska Högskolan framlägges till offentlig granskning för avläggande av teknologie doktorsexamen, fredagen den 18:e april, Abstract Maximum asset performance is one of the major goals for electric power distribution system operators (DSOs). To reach this goal minimal life cycle cost and maintenance optimization become crucial while meeting deman...

The aim of this paper is to propose Particles Swarm Optimization (PSO) to calculate the reliability index of a given structure. First of all, the basic modeling of time independent structure reliability is presented, and is followed by the optimization prob lem formulation to assess reliability index with PS O to overcome the difficulties of classical method to do a global search. Two applicati...

Most software reliability models for component-based software systems (CBSSs) depend on either the system architecture or component reliability and glue code reliability. It is important to optimize the usage of paths to obtain more accurate estimates of CBSS reliability. By using bio-inspired optimization techniques that are currently being developed, we can find the value of the most-used pat...
