The purpose of this research is to predict the failure of devices using a data mining tool. For this purpose, at the outset, an appropriate database consists of 392 records of ongoing failures in a pharmaceutical company in 1394, in the next step, by analyzing 9 characteristics and type of failure as a database class, analyzes have been used. In this regard, three decision tree algorithms have ...

Telomeres are protected and maintained by telomere-specific proteins. In addition, proteins involved in DNA repair, such as Mre11-Rad50-Nbs1 complex, RPA, and RecQ helicase, are also involved in telomere maintenance. In this review, the roles of these proteins in telomere maintenance and their functional relationships to the telomere-specific proteins will be discussed.

Long lasting systems like airplanes have a cost structure where the maintenance costs are larger than the purchasing costs. Testing is required, both for preventive maintenance as well as repair and a majpor source for cost. Previously we have analysed test and Design for Testability for digital systems, covering ASICs, boards and systems. Besides, the continuous development of technology requi...

Purpose – The purpose of this paper is to develop a model that incorporates the effect of rejection cost on optimal maintenance planning decisions. Such a model will help in further modelling the interrelationships between preventive maintenance and quality control policy. Design/methodology/approach – In this paper a model is developed for obtaining optimal preventive maintenance interval base...

This paper considers four options of warranty and preventive maintenance policy. The product is repairable and sold with a non-renewing free warranty policy. For products sold with warranty, preventive maintenance (PM) actions by manufacturers and/or buyers have an impact on the total costs for both parties. In this study, we deal with a model to study the effect of PM that carried out by the m...

Careful maintenance is essential to ensure the long-term serviceability of bridges. It is therefore necessary to establish a database which has a large capacity for storage of time-series data including structural properties at construction completion, inspection records, and repair and maintenance records, and which utilizes state-of-the-art information and telecommunication technologies to al...

Given the large expenditures on capital equipment characteristic of mining, technology developers and users alike place a very high priority on improving equipment productivity. Proper maintenance is essential to maximizing both availability and productivity. At the same time, maintenance services are a major cost element of all mine operations.1 Accordingly, after process optimization, equipme...

in today's competitive market, quality has an important role in manufacturing system. the manufacturers attempt to maintain their production system in a proper condition to produce high quality products. one of the key factors to achieve this goal is maintenance policy. most studies on maintenance focused on machines and less attention has been paid to human resources as the most important...
