Maintenance is a combination of multilateral and cross-functional activities and processes. Maintenance processes are identified in both strategic management and operation systems. Managers, engineers, technicians and operators collaboratively contribute in conducting and performing preventive or corrective maintenance activities. Maintenance management is to provide the longterm business strat...

Good maintainability is an essential feature for machines and processes in industry. It promotes, among others, maintenance safety, postmaintenance reliability and cost-effective maintenance by ensuring quick and easy operation and short downtime. Virtual engineering tools provide an effective way for maintainability design already during the design phase. Machine designers may not consider mai...

In this article we give an overview of the relation between planning of maintenance and production. On the one hand we consider production planning and scheduling models where failures and maintenance aspects are taken into account. Next we discuss the planning of maintenance activities, where we consider both preventive as well as corrective maintenance. Thirdly, we consider the planning of ma...

Deposition of waxes, asphaltenes, scales or hydrates is one the most challenging operational problems in oil and gas industry, both during production transportation. Direct inspection procedures, such as employing a closed-circuit television system, allow visual assessment blockage, yet discretely time and, consequently, low value for purpose ensuring over time. Therefore, an indirect predictiv...

many serious accidents have happened in the world, in which systems have been large-scale and complex, and caused heavy damage and a social sense of instability. furthermore, advanced nations have almost finished public infrastructure and rushed into a maintenance period. since maintenance is more important than production and construction, then more maintenance for environmental considerations...

this study shows the usefulness of artificial neural network (ann) in maintenance planning and man-agement. an ann model based on the multi-layer perceptron having three hidden layers and four processing elements per layer was built to predict the expected downtime resulting from a breakdown or a maintenance activity. the model achieved an accuracy of over 70% in predicting the expected downtime.
