maintenance is one of the systems which can play an essential role in the success of manufacturing and services systems. one of the most maintenance innovative approaches is agile maintenance. based on this approach, organizations integrate maintenance concepts with agility features such as: flexibility, agile and fast move, etc and also are trying to provide one hundred percent preparing equip...

Aircraft maintenance planning and scheduling constitute planning, control and execution of materials (spare parts), operations (inspection, disassembly and assembly activities) and resources (labour, machines, transport equipment, etc.). This is a complex problem due to large number of components involved at various planning and execution levels, and the size/nature of resource-intensive mainte...

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.

Telecommunications network operators are on a constant challenge to provide new services which require ubiquitous broadband access. In an attempt to do so, they are faced with many problems such as the network coverage or providing the guaranteed Quality of Service (QoS). Network planning is a multi-objective optimization problem which involves clustering the area of interest by minimizing a co...

Optram is a computer software for evaluation of track geometry quality data, used as a decision support in planning and follow-up of tamping maintenance for Swedish railways. The software was introduced at the Swedish Transport Administration year 2009 but has not reached the intended number of users. The purpose with this thesis is to suggest how Optram can be improved as a decision support in...

In this paper we present a method for estimating the quantity of resources to be used for correcting software errors in a period, during the software maintenance process, in such a way that the organisation that maintains the software has no economical losses. It is well known that software maintenance is the most costly stage of the software life cycle. So, it is important to provide technique...
