Many industrial sectors are concerned on developing optimal maintenance planning because of the importance of maintenance on the economy and safety. Traditionally, the maintenance planning is formulated in terms of a multi-objective optimization problem where reliability, availability, maintainability and cost act as decision criteria and surveillance test and maintenance strategies act as deci...

This research summary outlines and addresses three problems in casebased maintenance on case contents and adaptation rules: 1) how to perform maintenance on divisible cases with non-uniform sizes, 2) how can adaptation knowledge improve the performance of maintenance on structured cases, 3) how to determine and use coverage for adaptation rules. Evaluation showed that, for suitable cases bases,...

results there was significant reduction in anger symptoms of drug-dependent individuals after gross model based emotion regulation training (ert) (p < 0.001). moreover, the effectiveness of the training on anger was persistent in the follow-up period. conclusions symptoms of anger in drug-dependent individuals of this study were reduced by gross model-based emotion regulation strategies trainin...

Appropriate maintenance action can reduce maintenance expenses and improve maintenance benefits substantially. After introducing the definition and characteristics of risk-based maintenance (RBM), the authors describe the process of risk evaluation of equipment and put forward the maintenance strategies based on risk evaluation.

membrane-based technologies have increasingly been chosen in desalination processes, which is evidenced by the increase of large-scale plants constructed in recent years. indeed, several appropriate strategies should be considered to minimize problems faced during the construction, such as membrane system designs, area requirement, energy requirement, operation and maintenance, and environmenta...

Maintenance planning and activities have grown dramatically in importance across many industries and are increasingly recognized as drivers of competitiveness if managed appropriately. Correlated with this observation is the proliferation of maintenance optimization techniques in the technical literature. But while all these models deal with the cost of maintenance (as an objective function or ...

Materialized views defined over distributed data sources can be utilized by many applications to ensure better access, reliable performance, and high availability. Technology for maintaining materialized views is thus critical for providing upto-date results since a stale view extent may not help or even mislead these applications. State-of-the-art incremental view maintenance requires OðnÞ or ...

Data warehouse maintenance and maintenance cost has been well studied in the literature. Integrating data sources, in a data warehouse environment, may often need data cleaning, transformation, or any other function applied to the data in order to integrate it. The impact on view maintenance, when data is integrated with other comparison operators than defined in theta join, has, however, not b...

The present paper discusses the development of a Markov model for performance evaluation of coal handling unit of a thermal power plant using probabilistic approach. Coal handling unit ensures proper supply of coal for sound functioning of thermal Power Plant. In present paper, the coal handling unit consists of two subsystems with two possible states i.e. working and failed. Failure and repair...

Nowadays, offering extended warranty is considered as a lucrative source of income from the perspective of the after-sale service providers. Meanwhile, the main concern is presence or absence of base warranty and strategies adopted by the manufacturer during this period. Moreover, extended warranty structure must be responsive and customer oriented, which not only control the services cost but ...
