Theory and Practice for System Services Providers in Complex Value and Service Systems: ISSS 2013 Proceedings

In September 2013, the „International Symposium on Service Science (ISSS)“ offered various participants a unique platform for advancing research and discussions in service science for the fifth consecutive year. Being held as part of the “Leipzig Days of Applied Informatics/Leipziger Tage der Angewandten Informatik”, researchers and practitioners alike joined in their effort to better understand the emergence of system services providers in complex value chains and service systems. The proceedings book documents some of their insights and wants to serve as reference for the advancing discussion.:Research Paper Session: Stefan Kirn, Johannes Murray, Marc Premm, Michael Schüle, Tobias Widmer Towards a Research Framework for Multiagent Organizations Sven Tackenberg, Sönke Duckwitz, Christopher M.

Industrialising Software Development in Systems Integration

Compared to other disciplines, software engineering as of today is still dependent on craftsmanship of highly-skilled workers. However, with constantly increasing complexity and efforts, existing software engineering approaches appear more and more inefficient. A paradigm shift towards industrial production methods seems inevitable. Recent advances in academia and practice have lead to the availability of industrial key principles in software development as well. Specialization is represented in software product lines, standardization and systematic reuse are available with component-based development, and automation has become accessible through model-driven engineering. While each of the above is well researched in theory, only few cases of successful implementation in the industry are known. This becomes even more evident in specialized areas of software engineering such as systems integration. Today’s IT systems need to quickly adapt to new business requirements due to mergers and acquisitions and cooperations between enterprises. This certainly leads to integration efforts, i.e. joining different subsystems into a cohesive whole in order to provide new functionality. In such an environment. the application of industrial methods for software development seems even more important. Unfortunately, software development in this field is a highly complex and heterogeneous undertaking, as IT environments differ from customer to customer. In such settings, existing industrialization concepts would never break even due to one-time projects and thus insufficient economies of scale and scope. This present thesis, therefore, describes a novel approach for a more efficient implementation of prior key principles while considering the characteristics of software development for systems integration. After identifying the characteristics of the field and their affects on currently-known industrialization concepts, an organizational model for industrialized systems integration has thus been developed. It takes software product lines and adapts them in a way feasible for a systems integrator active in several business domains. The result is a three-tiered model consolidating recurring activities and reducing the efforts for individual product lines. For the implementation of component-based development, the present thesis assesses current component approaches and applies an integration metamodel to the most suitable one. This ensures a common understanding of systems integration across different product lines and thus alleviates component reuse, even across product line boundaries. The approach is furthermore aligned with the organizational model to depict in which way component-based development may be applied in industrialized systems integration. Automating software development in systems integration with model-driven engineering was found to be insufficient in its current state. The reason herefore lies in insufficient tool chains and a lack of modelling standards. As an alternative, an XML-based configuration of products within a software product line has been developed. It models a product line and its products with the help of a domain-specific language and utilizes stylesheet transformations to generate compliable artefacts. The approach has been tested for its feasibility within an exemplarily implementation following a real-world scenario. As not all aspects of industrialized systems integration could be simulated in a laboratory environment, the concept was furthermore validated during several expert interviews with industry representatives. Here, it was also possible to assess cultural and economic aspects. The thesis concludes with a detailed summary of the contributions to the field and suggests further areas of research in the context of industrialized systems integration

An intelligent framework for dynamic web services composition in the semantic web

As Web services are being increasingly adopted as the distributed computing technology of choice to securely publish application services beyond the firewall, the importance of composing them to create new, value-added service, is increasing. Thus far, the most successful practical approach to Web services composition, largely endorsed by the industry falls under the static composition category where the service selection and flow management are done a priori and manually. The second approach to web-services composition aspires to achieve more dynamic composition by semantically describing the process model of Web services and thus making it comprehensible to reasoning engines or software agents. The practical implementation of the dynamic composition approach is still in its infancy and many complex problems need to be resolved before it can be adopted outside the research communities. The investigation of automatic discovery and composition of Web services in this thesis resulted in the development of the eXtended Semantic Case Based Reasoner (XSCBR), which utilizes semantic web and AI methodology of Case Based Reasoning (CBR). Our framework uses OWL semantic descriptions extensively for implementing both the matchmaking profiles of the Web services and the components of the CBR engine. In this research, we have introduced the concept of runtime behaviour of services and consideration of that in Web services selection. The runtime behaviour of a service is a result of service execution and how the service will behave under different circumstances, which is difficult to presume prior to service execution. Moreover, we demonstrate that the accuracy of automatic matchmaking of Web services can be further improved by taking into account the adequacy of past matchmaking experiences for the requested task. Our XSCBR framework allows annotating such runtime experiences in terms of storing execution values of non-functional Web services parameters such as availability and response time into a case library. The XSCBR algorithm for matchmaking and discovery considers such stored Web services execution experiences to determine the adequacy of services for a particular task. We further extended our fundamental discovery and matchmaking algorithm to cater for web services composition. An intensive knowledge-based substitution approach was proposed to adapt the candidate service experiences to the requested solution before suggesting more complex and computationally taxing AI-based planning-based transformations. The inconsistency problem that occurs while adapting existing service composition solutions is addressed with a novel methodology based on Constraint Satisfaction Problem (CSP). From the outset, we adopted a pragmatic approach that focused on delivering an automated Web services discovery and composition solution with the minimum possible involvement of all composition participants: the service provider, the requestor and the service composer. The qualitative evaluation of the framework and the composition tools, together with the performance study of the XSCBR framework has verified that we were successful in achieving our goal

Smart Services and Service Science: Proceedings of the 4th Internaional Symposium on Services Science, Leipzig (Germany), September 25, 2012

Services Science is a new research discipline that has received, over the last years, a growing attention from academia and practice. It combines research from various fields which have evolved more or less independently and is concerned with the development and management of service products. Whereas theories from organizational and marketing science usually capture the nature of these products, engineering disciplines focus on shaping and developing these information goods, and the information systems field on integrating services as encapsulated application functionalities by using standardized (XML) interfaces. All these research streams converge in the new interdisciplinary area of Services Science which integrates the principles, design, and management of economic and technical services. For the fourth time, the \\\\\\\'International Symposium on Services Science (ISSS)\\\\\\\' offered an outstanding platform for the advancement and discussion of research in Service Science. In 2012, the ISSS focused on knowledge-intensive business services, also known as Smart Services, and their application in theory and practice. The ISSS was part of the Multi-Conference SABRE (Software, Agents and Services for Business, Research and E-Sciences, 24th-25th September 2012) and was held in Leipzig, Germany as a one-day event on the 25th September, 2012. The symposium was organized by the Information Systems Institute and the Department of Computer Science at the University of Leipzig as well as the Institute for Applied Informatics (InfAI), Fraunhofer MOEZ and the Leipziger Informatik-Verbund (LIV). As reflected in the conference proceedings, the sessions included in the agenda dealt with Smart Services from different perspectives: Smart Services in Theory and Practice, Smart Services in Management and Application, and Smart Services in High-Tech-Sectors. Although the official language of the conference is English, the authors had the opportunity to write their research contributions in English or German
