Maintenance is an indispensable part of the business process and plays an important role in an organisation’s success and survival. The main purpose of maintenance is to ensure equipment functions at its original optimal level. Thus, the knowledge and skills of operators are crucial and in demand. This paper presents a knowledge management of maintenance activities transfer method. Knowledge ma...

Technological advances, financial possibilities and changes of demands have increasingly affected the pavement maintenance environment for outsourcing in recent years. This induces complexity in the contracting methods of pavement maintenance activities. Despite the fact that current contracting practices on pavement maintenance activities are not sufficient to deal with changes providing the i...

In industrial environment, data generated during equipment maintenance and monitoring activities has become increasingly overwhelming. Data mining presents an opportunity to increase significantly the rate at which the volume of data can be turned into useful information. This paper presents an architecture designed to gather data generated in industrial units on their maintenance activities, a...

BEHAVIOR functions according to the principles of homeostasis and may therefore be called regulatory. The term "maintenance beh'avior" is used here to describe activities that help regulate the physiological state of the organism. When given in the presence of another organism, certain maintenance activities may have secondary, communicative effects through "sympathetic induction" causing socia...

This paper concerns the modelling of maintenance activities in a distributed context. In this work we study the particular case where the maintenance activities are executed by two workshops: a central maintenance workshop (CMW) and a mobile maintenance workshop (MMW). The (CMW) concerns the repairing process for the corrective maintenance and the (MMW) execute all preventive maintenance in sev...

We present a discrete-event simulation model for maintenance operations of a fleet of fighter aircraft in crisis situations, where the fleet operations are affected by a threat of an enemy's actions. The model describes the flight process and basic modes of periodic maintenance and failure repairs. Features that are specific to crisis situations include battle damages of the aircraft, decentral...

In this paper, a single-product, single-machine system under Markovian deterioration of machine condition and demand uncertainty is studied.  The objective is to find the optimal intervals for inspection and preventive maintenance activities in a condition-based maintenance planning with discrete monitoring framework. At first, a stochastic dynamic programming model whose state variable is the ...

Predictive Maintenance is the catchword in the present times. First ,the paper analyze the feature of the Predictive Maintenance, include scientific, approximation, timeliness, condition monitoring, fault diagnostic and so on, second the technology system for Predictive maintenance has been studied, including: condition monitoring technology, fault diagnosis technology, state prediction and mai...

Software maintenance involves different categories of activities: corrective, adaptive, perfective, and preventive. However, research regarding these distinct activities is hampered by lack of empirical data that is labeled to identify the type of maintenance being performed. A promising dataset is provided by the more than 800 versions of the Linux kernel that have been released since 1994. Th...

A key aspect of competition in industrial maintenance is the trade-off between cost and risk. Decision making is dependent upon up-to-date information about distributed and disparate plant, coupled with knowledge of sensitive non-technical issues. Enabling technologies such as the internet are making strides in improving the quantity and quality of data, particularly by improving links with oth...
