Manufacturing systems must be supported by the availability of materials, a streamlined production process and prepared line to achieve target. In mass customization manufacturing system, number machines required for is relatively small. Conse-quently, maintenance on critical will impact this system most. Two types strategies are implemented: corrective preventive maintenance. The requires more...

Dynamic security assessment (DSA) or transient security assessment (TSA) determines a system’s ability to survive contingencies with a safety factor (margin). To ensure that a system remains dynamically secure, preventive or corrective remedial actions are designed. Preventive actions are applied in the pre-contingency system so that after any credible contingency the system remains secure. Exa...

A complex multi-state redundant system with preventive maintenance subject to multiple events is considered. The online unit can undergo several types of failure: both internal and those provoked by external shocks. Multiple degradation levels are assumed as external. Degradation observed random inspections and, if they major, the goes a repair facility where carried out. This composed single r...

Many maintenance approaches have been developed and applied successfully in a variety of sectors such as aviation and nuclear industries over the years. Some of those have also been employed in the maritime industry such as condition based maintenance; however choosing the best maintenance approach has always been a big challenge due to the involvement of many attributes and alternatives which ...

Software maintenance constitutes a major phase of the software life cycle. Studies indicate that software maintenance is responsible for a significant percentage of a system’s overall cost and effort. The software engineering community has identified four major types of software maintenance, namely, corrective, perfective, adaptive, and preventive maintenance. Software maintenance can be seen f...

Age-replacement is one of the most commonly usedmaintenance policies based on preventive action to prevent system failure. Inmany age-replacement settings, it assumed that maintenance time can beignored since short compared with operation time. However, maintenance,especially corrective maintenance, may take a non-negligible amount dueto various factors such as ordering replacement parts, equip...

This paper analyses the production availability and associated maintenance costs of an offshore wind turbine with a horizontal axis configuration using Petri Nets modelling Monte Carlo Simulation. For this purpose, different features are implemented: reliability maintainability characteristics components; logistics operations, including types vessels, mobilization time, weather window. The stra...
