1 Multi-agent Systems Product Lines Camila Nunes, Elder Cirilo, Ingrid Nunes

2 Camila Nunes, Elder Cirilo e Ingrid Nunes © LES/PUC-Rio Outline Introduction Background Case Studies –ExpertCommittee –OLIS References

3 Camila Nunes, Elder Cirilo e Ingrid Nunes © LES/PUC-Rio Introduction Agent-oriented Software Engineering (AOSE) –New software engineering paradigm –Development of distributed complex applications Software Reuse –Benefits Lower costs Reduced time-to-market Quality improvement –AOSE methodologies Failed to adequately capture the reuse potential since many of the developed methodologies center on the development of specific software applications

4 Camila Nunes, Elder Cirilo e Ingrid Nunes © LES/PUC-Rio Introduction Software product lines (MAS) –New trend of software reuse –Build family of applications in a systematic method Only recent research has explored the integration between SPL and Multi-agent Systems (MAS) –Multi-agent Systems Product Lines (MAS-PL) –SPL + MAS benefits –Help on the industrial exploitation of agent technology

5 Camila Nunes, Elder Cirilo e Ingrid Nunes © LES/PUC-Rio Background Reuse: From Ad-Hoc to Systematic Focus was small-grained and opportunistic. Results always fell short of expectations.

6 Camila Nunes, Elder Cirilo e Ingrid Nunes © LES/PUC-Rio Background A software product line is a set of software-intensive systems sharing a common, managed set of features that satisfy the specific need of a particular market segment or mission and that are developed from a common set of core assets in a prescribed way. Software product line engineering is a paradigm to develop software applications (software-intensive systems and software products) using platforms and mass customisation. A software platform is a set of software subsystems and interfaces that form a common structure from which a set of derivative products can be efficiently developed and produced.

7 Camila Nunes, Elder Cirilo e Ingrid Nunes © LES/PUC-Rio Background Market Strategy / Application Domain pertain to Architecture share an Components are built from is satisfied by used to structure Products Product Lines: Take economic advantage of commonality Bound variability

8 Camila Nunes, Elder Cirilo e Ingrid Nunes © LES/PUC-Rio SPL Development Approaches Proactive Approach –Development of product lines considering all the products in the foreseeable horizon –A complete set of artifacts to address the product line is developed from scratch SPL Product 1 Product 2 Product 3 Domain Analysis Architecture Project

9 Camila Nunes, Elder Cirilo e Ingrid Nunes © LES/PUC-Rio SPL Development Approaches Extractive –SPL is developed starting from existing software systems –Common and variable features are extracted from these systems to derive an initial version of the SPL Product 1 Product 2 Product 3 SPL Product 1 Product 2 Product 3

10 Camila Nunes, Elder Cirilo e Ingrid Nunes © LES/PUC-Rio SPL Development Approaches Reactive –Incremental development of SPLs –SPL artifacts address only a few products. When there is a demand to incorporate new requirements or products, the common and variable artifacts are incrementally extended in reaction to them SPL Product 1 Product 2 Product 3 Requirements for a new product instance, Product 4 + SPL React Iterate Product 1 Product 2 Product 3 Product 4

11 Camila Nunes, Elder Cirilo e Ingrid Nunes © LES/PUC-Rio Case Studies

12 Camila Nunes, Elder Cirilo e Ingrid Nunes © LES/PUC-Rio ExpertCommittee (EC) Conference Management System Typical web-based application Functionalities to support the complete process of the management of conferences and workshops –Paper submission –Reviewing processes Examples –EasyChair (http://www.easychair.org/)http://www.easychair.org/ –JEMS (https://submissoes.sbc.org.br/)https://submissoes.sbc.org.br/

13 Camila Nunes, Elder Cirilo e Ingrid Nunes © LES/PUC-Rio EC Versions VersionDescription Version 1 Typical web-based application (MAS-PL core) Mandatory features that support the conference management process Version 2 Release 1: Addition of the Reviewer role and the functionalities related to it: accept/reject review and review paper. Release 2: Addition of automatic suggestion of conferences to the authors. Release 3: Addition of message notifications to the system users through or SMS (alternative feature). Release 4: Addition of deadline monitoring, to trigger specific actions when they expire. Release 5: Addition of automatic assignment of papers to committee members review them. Release 6: Addition of task management. Version 3Refactoring of Version 2 Improvement of the modularization of some agency features
