U-Test’s presentations in the Object Management Group Meeting in Brussels

5-9 June 2017, representatives from the U-Test consortium participated in the Object Management Group (OMG) meeting held in Brussels.

On June 7, Marc-Florian Wendland from Fraunhofer FOKUS presented the revised version of the UML Testing Profile (UTP) to the ADTF. OMG voted to adopt the revised UTP. The next phase of in the standardization activity is the Finalization Task Force (FTF). FTF aims at transforming the adopted specification into a formal specification.

As reported early, U-Test project members initiated the new Uncertainty Modelling (UM) standard. The researchers from Simula presented the current progress of UM in the ADTF meeting of OMG. Particularly, the responses that were collected from the RFI were analysed and presented to the ADTF. After the RFI was the kick-off the Request for Proposals (RFP) phase of the standardization activity. A wiki page for this standardization activity has been created on the OMG website. The wiki is continuously updated. Please check the following link for details: http://www.omgwiki.org/uncertainty/doku.php?id=start

Workshop: U-Test for the Realibility of IOT Solutions in the Manufacturing and Logistics Sectors

ULMA Handling, IK4-Ikerlan and the remaining U-Test partners invites to a workshop focusing on testing and scaling of smart and embedded systems (Internet of Things) in the manufacturing and logistics sector.

Background

The manufacturing and logistics sector becomes more and more dependent on sensors and connectivity as an integrated part of the products and services offered. The Industry 4.0 approach to digitalisation for productivity and growth will increase the use of integrated sensor based equipment in manufacturing facilities and logistics equipment and infrastructure. Cyber-physical systems (CPS) will monitor physical processes, and make decentralized decisions by communicating and cooperating over the Internet of Things (IOT) with each other and with humans. In consequence, the reliability and the quality assurance of such systems (typically budgeted around 50-70% of the total development cost) will be of paramount importance to improve the dependability of systems under development as the CPSs are often developed for critical domains.

The Fifth General Assembly hosted by EGM in Nice, 2017

During 11-12 May 2017, Easy Global Markets (EGM) hosted the fifth general assembly (GA) of U-Test project in the beautiful city Nice, France. During the two-day meeting, U-Test consortium members reviewed the suggestions from the second-year project review in Brussels, carefully synchronized the planning for the on-going work packages, and successfully made agreements on key steps in the last project year.

In April, the work efforts from the whole consortium during the second year were rewarded with very positive results from the second-year project review in Brussels. Therefore, the GA in Nice is a good chance for the project members to review the comments and suggestions from the second-year project review. All the comments and suggestions have been addressed thoroughly and reflected clearly into the on-going tasks of each work package. After the first two years, a strong foundation of research results, standardization initiatives, and tool chains for technology transfer has been created.

The project is now in the third year where the exploitation activities are prioritized to promote the testing tool chains to be adopted by industry. Especially, the commercialized testing tool chains U-CertifyIt developed by EGM could be offered to large CPS vendors/integrators and specialized SMEs that are part of the value chain for large CPS vendors. Indeed, the entire U-Test consortium is keeping up the momentum of good work in all active work packages with a strong focus on supporting the technology transfer and exploitation activities. All the tasks had been discussed among the consortium members for synchronization and optimization with agreements.

The fifth general assembly of U-Test consortium was successful. We had made agreements among all the partners on the key steps until end of 2017, to finish the project strongly with the focus on exploitation activities in the last project year. Many thanks to all the participants, and especially the great hospitality by EGM in Nice, France!

U-Test for the reliability of IoT solutions in the healthcare sector

On March 9th 2017, Oslo Medtech and other representatives of U-Test project hosted a workshop with the theme of IoT solutions in the healthcare sector. The workshop was held in Oslo Science Park and introduced the U-Test’s values for the reliability of IoT solutions in the healthcare sector.

In addition to the presentations of U-Test’s members, the workshop also involved the presentations of policy makers (from the Norwegian Directorate of eHealth) and other local projects in the healthcare sector in Norway.

Bent-Håkon Lauritzen from Oslo Medtech was the host and the event introduced Oslo Medtech.

He then gave the floor to Roar Olsen, the director for eHealth in Norway to present about the policies and challenges for implementation of embedded systems within healthcare in Norway.

Waqar Ahmed is the project coordinator and guided us through the main session of U-Test’s presentations.

Nordic Medtest has been running one of the pilots in the U-test project and Robert Magnusson presented the GeoSport case study. This is providing research and tool experimentations in the projects.

Phu Nguyen from Simula Research Lab and Bruno Legeard, the CTO from Easy Global Market (EGM) represented the research partners in U-Test. They presented the U-Test approaches for uncertainty testing of CPS/IoT, how uncertainty theories were studied that led to the creation of Uncertainty Taxonomy and finally showed how the testing approaches from research have been implemented into testing tools developed by EGM.

The latest version of U-CertifyIt was demonstrated to the audience that showed a highly automated tool support to generate test cases for tackling uncertainties in CPS/IoT systems. The “U-Test” session received good attention from the audience with highly interactive Q&A after each presentation.

To make it more practical, we had invited two projects from healthcare.  The first project EVIK project from the Department for e-health Municipality of Oslo, presented by Kjetil Moberg. His informative presentation gave the audience good insight into an IoT project for the public with all the challenges – from technical to human-related.

Following the EVIK presentation, the “Hospital at home: Information flow and operation of devices” from the project Medicloud. André Barkhald from Sykehuspartner inspired the audience on the development of Medicloud as the centre for connected care empowered by IoT and Data centres.

We concluded the seminar with workshops where we addressed the risks and challenges with integrated homecare solutions and IoT for healthcare in general.

OMG hosted a Webinar “Introduction to Uncertainty Modelling” presented by U-Test project members

Context: New technologies usually emerge and old technologies often evolve throughout the years. In this context, technology standards always play a key role in providing real-world value for technical-driven industries. Internationally recognised standardisation bodies such as the Object Management Group (OMG) drive the standardisation process by developing the integration standards for a wide range of technologies and an even wider range of industries. Therefore, the U-Test project team fully develop our technical solutions on existing and widely adopted standards such as OMG’s modelling standards, including the Unified Modelling Language (UML) and UML Testing Profile (UTP). We understand that this is an important strategy to improve the competitiveness of the consortium.
Furthermore, we even contribute in developing the standards with the U-Test’s results. To this end, U-Test team has been closely working with OMG towards standardising our Uncertainty Modelling approach. As a step closer towards standardising Uncertainty Modelling, OMG (represented by Andrew Watson, Vice President and Technical Director) hosted a webinar entitled “Introduction to Uncertainty Modelling” on January 25th, 2017. In the webinar, Tao Yue, Shaukat Ali, and Bran Selic presented the Uncertainty Modelling RFI (Request For Information). This is a big step in the standardisation activities of the project, a corner stone for building U-Test’s community. The webinar aimed at promoting the current Uncertainty Modelling approach of U-Test, and calling for feedbacks from the community. We are aware that uncertainty is a research topic shared in various fields including philosophy, physics and finance. The webinar went well with 215 registered, 137 live viewings, 123 downloads as counted 1 week after the webinar. More information about the webinar and the webinar itself can be found in this link: Uncertainty Modeling Webinar

About this webinar

The importance of facing, understanding, predicting and even mitigating uncertainty has been well acknowledged and studied in various fields such as philosophy, physics and finance.

In terms of software and system engineering, due to the increasing complex of large-scale systems themselves, and the dynamic and unpredictable deployment and operation environments of such systems, increasing attentions have been given to address challenges of explicitly specifying and modeling uncertainty.

Uncertainty Modeling (UM) aims to promote and enable explicit specifications of uncertainty and uncertainty related concepts, at various contexts (e.g., developing large-scale Cyber-Physical Systems and Internet of Things, for different purposes (e.g., enabling uncertainty-wise requirements specifications, modeling, verification and validation, e.g., facilitating the definition of uncertainty-wise testing strategies), and at different phases of the development of such complex and uncertainty-inherent systems (e.g., requirements, architecture, design, testing and operation).

In the context of OMG, we see a diverse set of uncertainty modeling applications, such as 1) integrating with UML use cases, SysML Requirements Diagram, to enable requirements V&V, 2) capturing uncertainty as part of SysML or UML models to facilitate design and/or testing, 3) integrating with BPMN and other OMG standards to facilitate different kinds of analyses and generations.

OMG’s Uncertainty Modeling Request for Information (RFI) is currently open for responses. The RFI aims to solicit ideas, discussions, comments, recommendations, user needs and experiences about uncertainty modeling. Collected responses will be carefully analyzed and will be used to identify requirements, based on an RFP for an UM will be developed. Instructions for responding to this RFI are specified in the OMG Uncertainty Modeling Request for Information document (ad/16-09-02 (Uncertainty RFI)).

We invite you to join the conversation.
Live online Jan 25 5:00 pm (Norway, Oslo)
Duration: 60 mins

Participation at the MPM4CPS COST Action Event

Several U-Test participants attended a workshop on modeling of Cyber-Physical Systems (CPSs) organized by MPM4CPS IC1404 COST action. In particular, participants from U-Test Consortium gave two talks and one demo. The first talk was about U-RUCM, which is a tool developed in the U-Test project about specifying uncertainty in requirements. The second talk was about U-Testing aimed at supporting test case generation from test ready models developed with Uncertainty Modeling Framework. The demo was about UncerTest, i.e., an uncertainty-wise test case generation tool implementing U-Testing. The demo showed the entire process from creating test ready models with uncertainty on a real case study, test case generation, and test case execution on the real case study at the runtime. The participants were funded by the COST action.
