Multi-objective optimisation of deployable bistable scissor structures

A Adapting Scientific Workflow Structures Using Multi-Objective Optimisation Strategies

Scientific workflows have become the primary mechanism for conducting analyses on distributed computing infrastructures such as grids and clouds. In recent years, the focus of optimisation within scientific workflows has primarily been on computational tasks and workflow makespan. However, as workflow-based analysis becomes ever more data intensive, data optimisation is becoming a prime concern...

‘multi-path’ Motion of Deployable Structures

A recently developed, rigid-panel deployable antenna has shown, unexpectedly, a kind of multi-path behaviour. A physical model of the antenna deploys automatically without problems but, during retraction, it attempts to follow an alternative path and gradually locks up. Manual intervention is necessary to take the model back to its nominal retraction path, and this successfully completes the re...

Multi-Objective Optimisation of Restricted Complexity Controllers

Restricted complexity controller design for the active suspension benchmark problem [1] is considered. The control design specifications of the benchmark is firstly recast into a mixed H∞/l1 optimisation problem, which is solved via a convex optimisation approach. A globally optimal Pareto curve is produced via the optimisation. It presents the limits of performance and is served as a reference...

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...
