1. ROSETTA: the challenge of escorting a comet and landing on its surface
Prof. Klaus Schilling, University of Würzburg, Germany
One of the most interesting places in our solar system was 2014/2015 moving between the orbits of Jupiter and Earth, when the European space probe ROSETTA had a rendezvous with the comet 67 P Churyumov-Gerasimenko. In November 2014 the PHILAE lander separated from the mother spacecraft and landed by a combination of autonomous reactions and remote controls from a distance of 500 Mio km with high accuracy on the surface of the comet. The unconventional landing ended due to actuator malfunctions in a very interesting cliff, where the foreseen measurements were nevertheless well performed. ROSETTA escorted the comet in near distance during the year 2015, including its passage of closest distance to the Sun in order to observe the development of its tail. This way sublimated pristine materials from the core of the comet could be characterized, providing information from the period when our solar system formed. Scientific journals like „Science“ and „nature“ selected the pioneering ROSETTA mission as scientific top event of the year 2014.
This presentation addresses the software and control background of this complex and challenging mission, which started about 25 years ago and had to respect ambitious technical as well as international challenges. The fascination of space exploration will be illustrated by pictures from this bizarre comet.

2. Addressing Assurance for Self-Adaptive Systems in the Face of Uncertainty
Prof. Betty H.C. Cheng, Michigan State University, USA
This presentation will overview several research projects that investigate novel ways to model, analyze, and mitigate uncertainty for self-adaptive cyber-physical systems, with a particular focus on assurance. First, uncertainty about the physical environment can lead to suboptimal, and sometimes catastrophic, results as the system tries to adapt to unanticipated or poorly-understood environmental conditions. Second, uncertainty in the cyber environment can lead to unexpected and adverse effects, including not only performance impacts (load, traffic, etc.) but also potential threats or overt attacks. Finally, uncertainty can exist with the components themselves and how they interact upon reconfiguration, including unexpected and unwanted feature interactions. Each of these sources of uncertainty can potentially be identified at different stages, respectively design time and run time, but their mitigation might be done at the same or at a different stage. Based on the related literature and our investigations, we argue that the following three overarching techniques are essential and warrant further research to provide enabling technologies to address uncertainty during both stages: model-based development, automated assurance techniques, and self-adaptation. Furthermore, we posit that in order to go beyond incremental improvements to current software engineering techniques, we need to infuse these three areas with successful techniques and inspirations from other disciplines, such as control theory, machine learning, and biology.
Betty H.C. Cheng is a professor in the Department of Computer Science and Engineering at Michigan State University. Her research interests include self-adaptive systems, requirements engineering, model-driven engineering, automated software engineering, and harnessing evolutionary computation to address software engineering problems.

3. Building Autonomic Systems for IT Service Management
Dr. Yixin Diao, IBM T. J. Watson Research Center, New York, USA
A large fraction of total cost of ownership for IT systems comes from service and labor costs (80% as estimated by Gartner Group). However, most prevailing practices in IT services are ad-hoc with low productivity. Although modeling and optimization techniques have been widely used in IT infrastructure management, their adoption in IT service management has limited success due to high uncertainties resulting from complex tasks and large human skill variance. This talk explores the principles and methodologies for building autonomic systems that enable a systematic and feedback-based approach to model and optimize IT service management. Particularly, I will discuss the design and deployment of a staffing (staffing levels, shifts, and skills) self-optimization system that uses the simulation-optimization techniques to enable accurate staffing decision-making, coupled with the feedback-based model validation techniques to address the unique service modeling challenges of employing massive data with large inaccuracies. The developed system has been deployed within the IBM’s globally located delivery organizations and resulted in improved resource usage, delivery efficiency, and service quality over a large number of service delivery teams. I will conclude this talk by discussing the future challenges and opportunities of growing autonomic computing capabilities in the IT service management space.

4. Cyber-physical control of road freight transport
Prof. Karl H. Johansson, KTH Royal Institute of Technology, Sweden
Freight transportation is of outmost importance for our society and is continuously increasing, particularly in the emerging economies. At the same time, transporting goods on roads accounts for about 26% of all energy consumption and 18% of greenhouse gas emissions in the European Union. Despite the influence the transportation system has on our energy consumption and the environment, road transportation is mainly done by individual long-haulage trucks with no real-time coordination or global optimization. In this talk, we discuss how modern information and communication technology supports a cyber-physical transportation system architecture with an integrated logistic system coordinating fleets of trucks traveling together in vehicle platoons. From the reduced air drag, platooning trucks traveling close together can save more than 10% of their fuel consumption. Control and estimation challenges and solutions on various level of this transportation system will be presented. It will be argued that a system architecture utilizing vehicle-to-vehicle and vehicle-to-infrastructure communication enable receding horizon optimal control of individual trucks as well as optimised vehicle fleet collaborations. Experiments done on European highways will illustrate system performance and safety requirements. The presentation will be based on joint work with collaborators at KTH and at the truck manufacturer Scania.

5. InfoSymbioticSystems/DDDAS – Large-Scale Dynamic Data and Large-Scale Big Computing for Smart Systems
Dr. Frederica Darema, Air Force Office of Scientific Research, USA
The presentation will discuss DDDAS, a paradigm which unifies systems’ modeling and instrumentation aspects, and is creating new and revolutionary capabilities for improved understanding, analysis, and optimized, autonomic management and decision support of operational of engineered and natural multi-entity systems, and including human and societal systems. Key underlying concept in DDDAS is the dynamic integration of instrumentation data and executing models of the system in a feedback control loop – that is on-line data are dynamically incorporated into the systems’ executing model, to improve the modeling accuracy or to speed-up the simulation, and in reverse the executing model controls the instrumentation to selectively and adaptively target the data collection process, and dynamically manage collective sets of sensors and controllers. DDDAS is timely with the advent of Large-Scale-Dynamic-Data and Large-Scale-Big-Computing. Large-Scale-Dynamic-Data encompasses the next wave of Big Data, and namely dynamic data arising from ubiquitous sensing and control in engineered, natural, and societal systems, through multitudes of heterogeneous sensors and controllers instrumenting these systems, and where the opportunities and challenges at these “large-scales” relate not only to the size of the data but the heterogeneity in data, data collection modalities, data fidelities, and timescales, ranging from real-time data to archival data. In tandem with this important dimension of dynamic data, there is an extended view of Big Computing, which includes a new dimension of computing – the collective computing by networked assemblies of multitudes of sensors and controllers, this range from the high-end to the real-time seamlessly integrated and unified, and comprising the Large-Scale-Big-Computing. In that context the traditional notions of Cloud-computing need also to be extended to also include the referenced range of the instrumentation platforms. The DDDAS paradigm, driving and exploiting these notions of Large-Scale Dynamic Data and Large-Scale Big Computing, is shaping research directions and engendering transformative impact in a range of natural and engineered systems application areas. Spanning environments from the nanoscale to the terra-scale and the extra-terra-scale environments, examples of advances and new capabilities that will be presented include: materials analysis and decision support for structural systems; manufacturing systems; cellular, neural, and biorobotic systems; environmental systems; critical infrastructure systems, such as urban and air transportation, energy powergrids, and smart agriculture.
