Available decision-support tools rarely account for the welfare of technicians in maintenance scheduling offshore wind farms. This creates uncertainties, especially since current operational limits might make a farm accessible but vibrations from transits be unacceptable to technicians. We explore technician exposure vibration transit based on levels discomfort and likelihood seasickness occurr...

Industrial organizations are complex systems` where the interactions among the various functions such as Sales, Distribution, Manufacturing, Materials, Finance, Human Resources and Maintenance have to be man-aged towards a common purpose of delivering the customers satisfaction. However, since most of these or-ganizations have a `Functional Structure`, each function or department works towards ...

Production planning and control (PPC) systems have to deal with rising complexity and dynamics. The complexity of planning tasks is due to some existing multiple variables and dynamic factors derived from uncertainties surrounding the PPC. Although literatures on exact scheduling algorithms, simulation approaches, and heuristic methods are extensive in production planning, they seem to be ineff...

Elastohydrodynamically lubricated (EHL) contacts are fundamental for several rotating machine elements. For example gears, rolling element bearings and lubricated chain drives work due to the principle of EHL. All of these machine elements require maintenance and, as condition based maintenance has increased in industry, the need for monitoring techniques has also increased. In order to avoid i...

In recent decades, by introducing lean manufacturing the vulnerability to system disturbances has increased and so, the demand for dependable production equipment. The need for having high production equipment availability causes companies to need a more effective and efficient maintenance strategy in order to stay competitive. Despite the increasing demand on reliable production equipment, few...

To reduce the levelized cost of wind energy, through reduction in operation and maintenance costs, it is imperative that turbine downtime reduced strategies based on condition monitoring. The standard approach toward this challenge vibration monitoring, which requires installation specific tailored sensors incur associated added costs. On other hand, life expectancy parks built during 1990s pow...

<p class="Abstract">Autonomous production control (APC) is able to deal with challenges, inter alia, high delivery accuracy, shorter planning horizons, increasing product and process complexity, frequent changes. However, several state-of-the-art approaches do not consider maintenance factors contributing operational tactical decisions in control. The incomprehensiveness of the decision m...

The growing complexity of systems and the need for executing large projects have led to the development of complex fl exible manufacturing systems (FMS) demanding specifi c control-monitoring architectures. The problem of failure occurrence tends to increase according to this complexity leading to time-consuming tasks as the localisation and repairing. The occurrence of failures during the expl...
