Conceptual Work

AbstractThis paper provides an overview about the conceptual work performed by the VDI/VDE GMA working group 7.21 towards the specification of a reference model for Industrie 4.0 service architectures. It focuses on the conceptual design of service-oriented architecture (SOA) relying upon the “I40 component” as a core basic concept across the whole value network. Furthermore, the paper discusses the relevance of reference models of the Internet of Things and Services as a foundation.

Self Adaptive

Service Oriented Systems (SOSs) based on the SOA paradigm are becoming popular thanks to a widely deployed internetworking infrastructure. They are composed by a possibly large number of heterogeneous third-party subsystems and usually operate in a highly varying execution environment, that makes it challenging to provide applications with Quality of Service (QoS) guarantees. A well-established approach to face the heterogeneous and varying operating environment is to design a SOS as a runtime self-adaptable software system, so that a prospective enterprise willing to realize a SOA application can dynamically choose the component services that best fit its requirements and the environment in which the application operates. In this chapter, the authors first review some representative frameworks that have been proposed for SOSs able to adaptively manage a SOA application with QoS requirements. These frameworks are commonly architected as self-adaptive systems following the MAPE-K (Monitor, Analyze, Plan, Execute, and Knowledge) reference model for autonomic computing. The chapter organizes the review using a specific taxonomy for each MAPE-K phase, with the aim to classify the different strategies and mechanisms that can be applied. Even if a self-adaptive system requires every MAPE-K phase, the authors then focus on the Plan phase, which is the core of each adaptation framework, presenting both optimal and sub-optimal approaches that have been proposed to effectively face the adaptation task at runtime.

Ict Security

The work presents the essence of problems appearing in the ICT security management process in the context of systems characterized by significant dynamics of configuration and heterogeneity of resources both in the hardware and software layer. Basic differences in security management in systems with traditional centralized and monolithic architecture as well as in systems with service-oriented architecture have been presented. A layered reference model for service-oriented systems taking account of the basic goals of ICT security for dynamic information systems has been discussed. The basic assumptions of the multi-agent ICT security analysis system in service-oriented systems as well as the results of the safety analysis, including the correlation between events observed in low and high layers of the reference model have been discussed.

Straipsnyje nagrinėjamas elektroninių paslaugų modeliavimas viešajame sektoriuje. Pateikiamas elektroninės paslaugos modelis buvo sukurtas remiantis į paslaugas orientuotos architektūros abstrakčiuoju modeliu. Modeliavimo procesas yra grindžiamas nuolatinio proceso tobulinimo idėja. Bendrojo elektroninių paslaugų modelio tikslas – skatinti partnerystę, dalytis žiniomis ir turima informacija tarp viešojo sektoriaus valdžios institucijų, atsakingų už elektroninių paslaugų kūrimą ir teikimą, siekiančių pagerinti jų teikiamų paslaugų veiksmingumą ir kokybę. Modelis gali būti naudingas atskleidžiant bendras problemas, standartizuojant elektroninių paslaugų modeliavimo ir konstravimo procesus, visoms suinteresuotoms šalims ieškant optimalių sprendimų. Pateiktasis modelis buvo išbandytas kuriant transporto priemonių registravimo elektroninę paslaugą ir gali būti naudojamas kuriant ir kitas viešas elektronines paslaugas, kurios gali būti teikiamos „vieno langelio“ elektroninės valdžios vartuose. Pasiūlytą modelį galima naudoti vertinant elektroninių paslaugų brandą ir jų bei jas realizuojančių sistemų sudėtingumą, taip pat lyginant tam tikras elektronines paslaugas tarpusavyje. Kaip technologinis sprendimas, kuriant tokių elektroninių paslaugų sistemas, yra pasiūlyta į paslaugas orientuota architektūra, kuria siekiama sukurti išplečiamas, lanksčias ir daug kartų lengvai panaudojamas sistemas.Modeling E-services in Public SectorEgidijus Ostašius, Živilė Petravičiūtė SummaryAbstract. This article focuses on the modeling of e-services in the public sector. The approach is based on the reference model for service-oriented architecture (SOA). The modeling process is based on the idea of the Continuous improvement process. The common model is aimed to stimulate partnership among the public sector authorities involved in e-service constructing and delivery and should improve the efficiency and effectiveness of their activities, the quality of services by sharing knowledge, common services and information. It could be helpful to understand the specific issues in common problems that are related to the subject, to standardize the processes of e-services modeling and construction while seeking the optimal solutions for all parties. The proposed model was tested on the e-service of vehicle registration and could be used for building other public e-services in one-stop e-government. The proposed e-service model could be also used for evaluating the maturity and complexity of e-services systems and for comparison of particular e-services. The SOA architectural framework is proposed as a solution to reach the scalability, flexibility and reusability in building an e-service system.Keywords: generic e-service model, one-stop e-government, service-oriented architecture (SOA), reference model for SOA, business process automation, business engineering, continuous improvement process, vehicle registration.

The Internet Of Things

The current generation of connected devices and the Internet of Things augment people’s capabilities through ambient intelligence. Ambient Intelligence (AmI) support systems contain applications consuming available services in the environment to serve users. A well-known design of these applications follows a service architecture style and implement artificial intelligence mechanisms to maintain an awareness of the context: The service architecture style enables the distribution of capabilities and facilitates interoperability. Intelligence and context-awareness provide an adaptation of the environment to improve the interaction. Smart objects in distributed deployments and the increasing machine awareness of devices and people context also lead us to architectures, including self-governed policies providing self-service. We have systematically reviewed and analyzed ambient system governance considering service-oriented architecture (SOA) as a reference model. We applied a systematic mapping process obtaining 198 papers for screening (out of 712 obtained after conducting searches in research databases). We then reviewed and categorized 68 papers related to 48 research projects selected by fulfilling ambient intelligence and SOA principles and concepts. This paper presents the result of our analysis, including the existing governance designs, the distribution of adopted characteristics, and the trend to incorporate service in the context-aware process. We also discuss the identified challenges and analyze research directions.
