The number of component instances required is typically unknown when defining the systems' architecture and variability but depends on customer requirements only known during configuration. The hierarchy of dynamically created component instances further results in complex dependencies between configuration decisions. To deal with the multiplicity and hierarchy of components product line engineers thus need a modeling approach capable of expressing the dependencies among dynamically instantiated components and related configuration decisions. Decision-oriented variability modeling approaches are highly useful in product line engineering to support product derivation and to guide users through the configuration process. However, current approaches do not sufficiently support multiplicity and hierarchy. In this paper we report on extending an existing decision-oriented approach to support modeling component variability, multiplicity, and hierarchy in product line architectures.","PeriodicalId":405927,"journal":{"name":"WICSA '14 Companion","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121338170","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is hence of great importance to repair erosion efficiently. Refactorings can help to systematically reverse software architecture erosion through applying them in the system where architectural violations have been detected. However, existing refactoring approaches do not address architecture erosion holistically.\u0000 In this paper, we describe and formalize the theoretical problem of repairing eroded software systems by finding optimal repair sequences. Furthermore, we investigate the applicability and limitations of existing refactoring approaches. We argue, true to the motto \"more knowledge means less search\" that using formalized and explicit knowledge of software engineers---modeled as fault patterns and repair strategies---combined with heuristic search techniques could overcome those limitations.\u0000 This paper outlines a new approach---analog to a patient history in medicine---we have been starting to investigate in our recent research and also aims at stimulating a discussion about further research challenges in repairing eroded software systems.","PeriodicalId":405927,"journal":{"name":"WICSA '14 Companion","volume":"91 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124419086","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In an architectural context for cloud systems that demand elasticity in terms of service availability, reliability, and efficiency, there is a need to capitalise on the 'build-once, use-often' solutions that support reuse-driven self-adaptations of cloud-based architectures. We support the composition and application of a pattern language that exploits adaptation patterns and their relations to support 'adaptation-off-the-shelf' for cloud-based software architectures. We unify the concepts of software repository mining and software evolution to support the composition and application of an adaptation pattern language. First, we exploit the software repository mining concepts by investigating adaptation logs to empirically discover architecture adaptation patterns and their relations. Second, we utilise the software evolution techniques for self-adaptation of cloud architectures guided by a systematic selection and application of adaptation patterns. In the context of the IBM'S MAPE-K model for self-adaptation, we propose reusable policies for self-adaptive cloud architectures. Architectural adaptation knowledge in the proposed pattern language is expressed as a formalised collection of interconnected-patterns. Individual patterns in the language build on each other to provide a generic and reusable solution to address the recurring adaptation problems. In future, we focus on an incremental evolution of pattern language by discovering new patterns from adaptation logs over time.","PeriodicalId":405927,"journal":{"name":"WICSA '14 Companion","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130421030","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The limited support for performing collaborative development and engineering activities and lack of sufficient support for maintaining and resolving dependencies and traceability across heterogeneous tools are major challenges for GSD teams. The lack of insufficient support for cross platform tools integration also makes it hard to address the stated challenges using existing paradigms that are based upon desktop and web-based solutions. The restricted ability of the organizations to have desired alignment of tools with software engineering and development processes results in administrative and managerial overhead that incur increased development cost and poor product quality. Moreover, stakeholders involved in the projects have specific constraints regarding availability and deployments of the tools. The artifacts and data produced or consumed by the tools need to be governed according to the constraints and corresponding quality of service (QoS) parameters. In this paper, we present the research agenda to leverage cloud-computing paradigm for addressing above-mentioned issues by providing a framework to select appropriate tools as well as associated services and reference architecture of the cloud-enabled middleware platform that allows on demand provisioning of software engineering Tools as a Service (TaaS) with focus on integration of tools.","PeriodicalId":405927,"journal":{"name":"WICSA '14 Companion","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129543794","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Their purpose is therefore to be a guidance for the development, standardization, and evolution of systems of such domains or neighbor domains. Adequate representation of such architectures is essential to promote their effective use and dissemination, using, for instance, different architectural viewpoints. A comprehensive description of reference architectures should not only record common features and functionalities, but also variations that could be present in the instances of these architectures. In this scenario, the main contribution of our work is to propose an architecture viewpoint to represent variability in reference architectures. We also describe the steps for creating such viewpoint and present an example of a technique that could be used to represent it. A case study is also presented, demonstrating the feasibility of our approach. Based on initial results, we have observed that the variability viewpoint could contribute to a more adequate, complete description of reference architectures and, as a consequence, it could promote a more effective dissemination and use of such architectures.","PeriodicalId":405927,"journal":{"name":"WICSA '14 Companion","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122157031","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
