Condition-based maintenance (CBM) is becoming increasingly important due to the development of advanced sensor and information technology, which facilitates the remote collection of condition data. We propose a new CBM policy for multi-component systems with continuous stochastic deteriorations. To reduce the high setup cost of maintenance, a joint maintenance interval is introduced. With this ...

The National Bridge Stock of Iran consists of about 330,000 bridges, of which around 50% are older than 30 years. Since 2010, Iran Road Maintenance & Transportation Organization has started implementing a comprehensive Bridge Management System in order to manage this aged stock efficiently. To predict future conditions of bridge stock, a heuristic numerical method is presented. This methodology...

This paper studies the problem of integrated lot-sizing and maintenance decision making in case multiple products stochastic demand. The is formulated as a Markov process, which goal to find joint production policy that minimizes long run expected total discounted cost. Therefore, classic Q-learning algorithm adopted, decomposition-based approximate Q-value heuristic developed obtain near-optim...

High costs of maintenance and lost production during downtime are a challenge to the offshore wind industry, there is great potential improve cost efficiency by improved control strategies utilizing condition monitoring information. As farms get older, also an increased need find ways extending lifetime turbines allowing continued operation. This may be obtained de-rating strategies, meaning ad...
