Application of data mining in a maintenance system for failure prediction
Bastos, Pedro; Lopes, Isabel; Pires, L.C.M.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, and to forecast fu...
SNMPFS - an SNMP filesystem
Lopes, Rui Pedro; Pedrosa, Tiago; Pires, L.C.M.The intensive operation of constantly growing, heterogeneous networks is a challenging task. Besides the increase in size and complexity, data networks have become a critical factor for the success of many organizations. During the last decade, many network management architectures where developed and standardized, aiming at the definition of an open environment to control and optimize its operation. Many of th...
A maintenance prediction system using data mining techniques
Bastos, Pedro; Lopes, Isabel; Pires, L.C.M.In the last years we have assisted to several and deep changes in industrial companies, mainly due to market dynamics and the need to converge with a globalized and impatient world. These changes are transversal to the entire company also impacting on company maintenance function. In an attempt to eliminate faults and keep systems running without interruption, companies incorporated tools into their Information...
SPAMUF: a behaviour-based maintenance prediction system
Bastos, Pedro; Lopes, Isabel; Pires, L.C.M.In the last years we have assisted to several and deep changes in industrial manufacturing. Many industrial processes are now automated in order to ensure the quality of production and to minimize costs. Manufacturing enterprises have been collecting and storing more and more current, detailed and accurate production relevant data. The data stores offer enormous potential as source of new knowledge, but the hug...
A decentralized predictive maintenance system based on data mining concepts
Lopes, Isabel; Pires, L.C.M.; Bastos, PedroIn the last years we have assisted to several and deep changes in industrial manufacturing. Induced by the need of increasing efficiency, bigger flexibility, better quality and lower costs, it became more complex [1]. Enterprises had had the need to cope with market expectations, incorporating in their production philosophies new paradigms such as JIT- Just in time, MTOMake to order, Mass Customization, agile ...
Montesinho Natural Park: general description and natural values
Castro, José; Figueiredo, Tomás de; Fonseca, Felícia; Castro, João Paulo; Nobre, Sílvia; Pires, L.C.M.The Montesinho Natural Park (PNM, Parque Natural de Montesinho) is a protected area located in the municipalities of Vinhais and Bragança, in the administrative NUT Alto Trás-os-Montes (PTlI8), the mountainous region of northeast Portugal. It was created in 1979 and consists of 748 km2 of natural wooded landscape and traditional mountain agricultural landscape, with highly variable gradients. PNM lies in the va...
Maintenance behaviour-based prediction system using data mining
Bastos, Pedro; Lopes, Rui Pedro; Pires, L.C.M.; Pedrosa, TiagoIn the last years we have assisted to several and deep changes in industrial manufacturing. Induced by the need of increasing efficiency, bigger flexibility, better quality and lower costs, it became more complex. The complexity of this new scenario has caused big pressure under enterprises production systems and consequently in its maintenance systems. Manufacturing systems recognize high level costs due equip...

Profiling computer energy consumption on organizations
Lopes, Rui Pedro; Pires, L.C.M.; Pedrosa, Tiago; Marian, VasileModern organizations depend on computers to work. Text processing, CAD, CAM, simulation, statistical analysis and so on are fundamental for maintaining high degree of productivity and competitiveness. Computers in an organization, consume a considerable percentage of the overall energy and, although a typical computer provides power saving technologies, such as suspending or hibernating components, this feature...
