Optimising Maintenance: What are the expectations for Cyber Physical Systems

The paper “Optimising Maintenance: What are the expectations for Cyber Physical Systems” has been presented at the 3rd International Workshop on Emerging Ideas and Trends in Engineering of Cyber-Physical Systems, EITEC’16. This workshop was held at the CPS Week 2016 in Vienna, Austria. The paper is the result of a collaboration between four MANTIS partners: Erkki Jantunen (VTT), Urko Zurutuza (MGEP), Luis Lino Ferreira (ISEP) and Pal Varga (BME). You can download the paper in the Dissemination section of the web.

Abstract—The need for maintenance is based on the wear of components of machinery. If this need can be defined reliably beforehand so that no unpredicted failures take place then the maintenance actions can be carried out economically with minimum disturbance to production. There are two basic challenges in solving the above. First understanding the development of wear and failures, and second managing the measurement and diagnosis of such parameters that can reveal the development of wear. In principle the development of wear and failures can be predicted through monitoring time, load or wear as such. Monitoring time is not very efficient, as there are only limited numbers of components that suffer from aging which as such is result of chemical wear i.e. changes in the material. In most cases the loading of components influences their wear. In principle the loading can be stable or varying in nature. Of these two cases the varying load case is much more challenging than the stable one. The monitoring of wear can be done either directly e.g. optical methods or indirectly e.g. vibration. Monitoring actual wear is naturally the most reliable approach, but it often means that additional investments are needed. The paper discusses the above issues and what are the requirements that follow from these for optimising maintenance based of the use of Cyber Physical Systems.

Kick-off meeting of the MANTIS project

The first MANTIS project meeting tool place in San Sebastian the 3rd of June 2015. The meeting was organized by the coordinator partner, Mondragon University, and 64 participants took place.

We discussed the organizational structures, shared information on project management, the tools that will be used for managing all aspects of the project, as well as constitution of the decision bodies (General Assembly, Executive Board and External Advisory Board).

The second day the meeting was split in 4 different Working groups, which corresponded to Requirements gathering, Architecture development, Sensors and Intelligent systems to be used in the MANTIS proactive maintenance platform.
