This paper draws on the “human reliability” concept as a structure for gaining insight into the maintenance workforce assessment in a process industry. Human reliability hinges on developing the reliability of humans to a threshold that guides the maintenance workforce to execute accurate decisions within the limits of resources and time allocations. This concept offers a worthwhile point of de...

A boolean particle swarm optimisation (PSO) algorithm is presented that builds on the strengths of earlier proposals but which by introducing a wholly random element into the search process shows greatly improved performance in higher dimensional search spaces in comparison also to the binary PSO algorithm of Kennedy and Eberhart.

Firefly algorithm (FA) is a new meta-heuristic optimisation algorithm that mimics the social behaviour of fireflies flying in the tropical and temperate summer sky. In this study, a novel application of FA is presented as it is applied to solve tracking problem. A general optimisation-based tracking architecture is proposed and the parameters’ sensitivity and adjustment of the FA in tracking sy...
