Multi-objective optimisation of asset maintenance management

Asset managers are faced with the necessity to reduce total life-cycle costs of their facilities as well as to improve their physical condition and long-term performance while considering the relative consequences of their failure. This paper presents a systematic decision-making approach for asset maintenance management that combines a stochastic Markovian performance prediction model with a m...

A multi-objective optimisation approach to water management.

The management of river basins is complex especially when decisions about environmental flows are considered in addition to those concerning urban and agricultural water demand. The solution to these complex decision problems requires the use of mathematical techniques that are formulated to take into account conflicting objectives. Many optimization models exist for water management systems bu...

Multi-objective Binary Search Optimisation

Preferences in Evolutionary Multi-Objective Optimisation

Multi-objective optimisation (MOO) is an important class of problem in engineering. The conflict of objectives in MOO places the issue of compromise in a central position. Since no single solution optimises all objectives, decision-making based on human preference is a part in solving MOO problems. In this paper application of the evolutionary MOO to the dynamic system controller design by use ...

Multi-objective particle swarm optimisation methods

This study compares a number of selection regimes for the choosing of global best (gbest) and personal best (pbest) for swarm members in multi-objective particle swarm optimisation (MOPSO). Two distinct gbest selection techniques are shown to exist in the literature, those that do not restrict the selection of archive members and those with ‘distance’ based gbest selection techniques. Theoretic...
