Cyber Physical System based Proactive Collaborative Maintenance

Periodic Reporting for period 3 - MANTIS (Cyber Physical System based Proactive Collaborative Maintenance)

Reporting period: 2017-06-01 to 2018-07-31

MANTIS addressed a proactive maintenance service platform architecture that allows to estimate future performance, to predict and prevent imminent failures and to schedule proactive maintenance. The proactive maintenance service platform architecture consists of distributed processing chains that efficiently transform raw data into knowledge while minimising the need for transfer bandwidth.

Vision and grand challenges
Our vision was to enable collaborative maintenance ecosystems by cyber physical systems. The grand challenges were developing new smart sensors and actuators, a service platform architecture for collaborative maintenance, intelligent algorithms and human-machine interaction to integrate with other existing technologies and tested in laboratory environment first and validated in four industrially relevant environments after.

We assumed that a service-based approach was the most feasible technology that enabled collaborative maintenance in an open-network environment connecting many cyber physical systems.

The success of MANTIS technology depended not only on the technology but also on the capability to create and pursue innovations supported by the core of our technology. The approach strongly contributed to the generation of new business models based on maintenance servitization of the products and assets that Partners sell or use and maintain.

The objective of the MANTIS project was to address the technical and applicative challenges associated to collaborative maintenance:
• Provide a technical framework adapted in terms of functions and performances
• Implement and evaluate the collaborative maintenance through real experimentations in four applicative domains: production assets, vehicles, energy production and health equipment
• Point out the accessible innovations thanks to new services
• Lead the way to further standardization work

The strategy adopted in the project had four major dimensions:
• An innovation strategy based on business and technology gap analysis paired with a market implementation strategy based on end users priorities and long term technology strategies
• Application pilots where technology demonstrations in real working environments were made
• A technology framework enabling collaborative automation and closing innovation critical technology gaps
• An innovation coordination methodology for complex innovation “orchestration”
The MANTIS project started on May the 1st 2015 with duration of 39 months. The partners have worked hard to achieve the pending milestones of the project. In a cooperative manner, many of the partners have outperformed expectations, and produced the work, in terms of submitted deliverables and the creation of a Book that summarizes all the work that can be made public.

Next, we list the major achievements obtained after the three periods of work:

• There exists a MANTIS reference architecture, that has been published in several research papers, is the principal content of the MANTIS Book (Open Access) and is already being used by a follow-up H2020 FoF project and partners that continued their own MANTIS implementations.
• There exist a number of cyber-physical systems, cloud services and many components of different nature in the plethora of use cases that have validated the MANTIS Maintenance architecture. Those need a clear guidance for interoperability that was provided in the form of Deliverables, and also as Open Access Book chapter.
• We have learnt how to select the optimal sensors that can provide the wear related information of a specific component, what type of intelligent functions are available to provide higher knowledge level and have validated them. We have researched on how to communicate the sensors in challenging environments, even restricting the bandwidth they need to provide information. And more importantly, we have made several processes of design, develop, and validation of new sensors to the community. These all have been documented in Deliverables related to the WP3.
• We have proposed, created, described and validated Artificial Intelligence algorithms in the form of algorithm portfolios, so the industry can similarly use or apply them, based on our experience, and the type of data we are facing with. There exist validated examples in most of the 11 use cases of MANTIS. Those apply for Root Cause Analysis, Remaining Useful Life prediction, Failure prediction, Maintenance Optimisation, and collaborative decision making.
• We have made and published a valuable exercise on how different maintenance scenarios can be translated into Human-Machine Interfaces, representing data in different interface types (from Web UIs to AR and VR), that can be interacted with. There are a number of HMIs developed in the project that demonstrate different approaches to Maintenance interaction.
• We have matured a number of new, Industrial Business Models, and will show the Industry how can a Maintenance Business Model be transformed into an Innovative product and service-based Business Model, and what is even better, have been able to generate a model for economic evaluation and quantification of the process of transforming current models into the innovative ones.
• All of the Use Cases have integrated and most of them have validated the technologies created under the same Maintenance Architecture Framework. More than the 80% of all the use-case scenarios have been satisfied.
• We have reached scientific audience with more than 50 research papers, we have transferred the MANTIS experience to University students, other Industry and potential customers in Europe through Fairs, we have created audio-visual material and leave it open in YouTube, we have created plenty of MANTIS related content in the Web that generated almost 38,000 page views, and finally, we made an intense, collaborative effort to publish most of our work, that planned to be confidential, but will live as an Open Access Book called “the MANTIS Book: Cyber Physical System Based Proactive Collaborative Maintenance”. We expect to have it published by July.
The MANTIS developments and definitions have taken more than 50 standards into account in order to start from an state of the art position, and progress beyond it in the three periods. However, MANTIS has given the first grounds towards the Proactive Maintenance. Nowadays predictive maintenance scenarios seem to be the most advanced ones, but MANTIS has built further concepts, where proactiveness is achieved with maintenance strategy optimization, as well as root cause analysis, with special attention to how the maintenance operators interactuate with the equipment that needs attention.
