Specifically, the workshop developed a research agenda that identified the key issues and challenges, and explored new approaches and tools for future collaborative decision making, including the use of social networks and Web resources, dynamic spatialtemporal decision making, and technical and social aspects of web-based decision processes. The applications range includes: environmental management; collaborative supply chains and resource allocation; finances; co-authoring collaboration network; disaster and crisis management; forecast information systems; and skiing accident prevention, among others. This rich diversity of areas and approaches to the design, implementation and usage of Decision Systems within this Workshop, is itself an invaluable source of inspiration, for our further investigations in the area.

These diverse areas are characterized by different paradigms, methods of inquiry and goals. But we focus on common challenges, including the problems faced by decision makers who must address tensions and conflicts through all phases of negotiations and group decision processes. These challenges require researchers to understand both the dynamics of independent entities and the consequences of their interactions. To provide practitioners with knowledge and tools, researchers construct models and systems that can not only aid decision makers, but in some cases undertake decisionrelated activities on their behalf. As in all previous GDN meetings, Melvin F. Shakun has led us with his good spirit and a helping hand. He, together with

COST has been supporting the networking of research activities across all 35 Member Countries and beyond for over 40 years. In H2020 COST will continue to follow the basic principles that made it a success since its foundation: excellence, openness, inclusiveness and bottom up. In 2013, the COST member states established a new implementing structure, the COST Association that will allow an even more efficient and research friendly management. Currently there is a scientific reorganization on going and a new submission, evaluation & selection procedure is being discussed. COST will reinforce its policies in the H2020 context allowing contributing to the Innovation Union's goal.

This knowledge would help telephone companies to make timely strategic decisions in our evolving economic environment where traditional communication technologies are declining. This study assesses to which extent two alternative networks might (1) structurally substitute this network and (2) complement this network for churn prediction within telephone companies.

Initially, this platform will collect data from the Google Scholar publication database. The Collab-Net platform aims to investigate these publication relationships in an automatic way, allowing researchers to analyze their own collaborative network. Moreover, also allows possibilities for future collaboration among EWG-DSS members only using a Web-based platform, anywhere at any time. Another relevant feature of the Collab-Net system is to enable two kinds of end-users profiles (administrator and member) with their specific access permission in the system. This report describes the specifications, versions, and recent web-based platform developed of the EWG-DSS Collaboration Network Project (EWG-DSS-Collab-Net), # Email Name Affiliation / Country

This is the case for anomaly detection that received a particular attention from the machine learning community, and resulted in a use of generative adversarial networks (GANs). In this work, we propose to use intermediate patches for the inference step, after a WGAN training procedure suitable for highly imbalanced datasets, to make the anomaly detection possible on full size Printed Circuit Board Assembly (PCBA) images. We therefore show that our technique can be used to support or replace actual industrial image processing algorithms, as well as to avoid a waste of time for industries.

Most of them leave the interpretation task to the analyst, or involve an implicit conception of language which is rarely questioned. Developed in the context of the EFFaTA-MeM (Evocative Framework For Text Analysis-Mediality Models) trans-disciplinary research project, the Evoq software takes a radically innovative approach. It voluntarily integrates concepts from post-structuralism theory which are thus offered as a reading sieve at the analyst's disposal. This demo paper briefly introduces the main concepts of poststructuralism, then it presents how these concept are modelised in a formal system. Finally, it shows how this approach is integrated in the Evoq software and how the human scientist can benefit from its functionalities.

It has not been different in Brazil. High crime rates have encouraged government authorities involved in public safety to identify solutions to minimize crimes considered VCA (Violent Crime Against Assets). In this context, one alternative to both plan and manage security is in the division of ISA (Integrated Security Areas) neighborhoods. However, the local government needs to identify the degree of crime severity of each ISA in order to establish prevention policies and, therefore, resources management, which will make it possible for the Secretariat for Social Defense and other entities involved to establish sets of actions intending to minimize the crime rate. Furthermore, it is evident that changes are constantly happening in the crime behavior tendencies in each ISA, requiring a different set of daily actions from authorities. Therefore, the purpose of this study is to...

The theme of the event was Big Data Analytics for Decision-Making and it was organized by the EURO (Association of European Operational Research Societies) working group of Decision Support Systems (EWG-DSS).The eight papers presented in this book were selected out of 26 submissions after being carefully reviewed by at least three internationally known experts from the ICDSST 2015 Program Committee and external invited reviewers. The selected papers are representative of current and relevant research activities in the area of decision support systems, such as decision analysis for enterprise systems and non-hierarchical networks, integrated solutions for decision support and knowledge management in distributed environments, decision support system evaluations and analysis through social networks, and decision support system applications in real-world environments. The volume is completed by an additional invited paper on big data decision-making use cases.

Nevertheless, industrial proposals such as TSpaces and JavaSpaces, inspired from Linda, have incorporated time constructs. This paper aims at a systematic study of the introduction of absolute time in coordination models. It builds upon previous work to

Computations in this language are described by means of an operational semantics, reporting the whole traces of executions. The non-compositionality of this intuitive operational semantics motivates the design of a compositional and fully abstract denotational semantics, which is then exploited for studying program equivalence in this setting.

Nevertheless, industrial proposals such as TSpaces and JavaSpaces, inspired from Linda, have incorporated time constructs. This paper aims at a systematic study of the introduction of relative time in coordination models. It builds upon previous work to study the expressiveness of Linda, Linda extended with a delay mechanism and Linda primitives extended to support the duration of tuples and of the suspension of communication operations.

The languages manipulate tokens associated in different ways with a notion of multiplicity. Thanks to De Boer and Palamidessi's notion of modular embedding, we establish expressiveness hierarchies. We also discuss implementation issues and argue that the more expressive the language is the more expensive is its implementation.

The Collab-Net platform aims to investigate these publication relationship in an automatic way by a Web-based platform. The present system was developed using free platforms for software development and database system purposes. The main goal of the Collab-Net is to allow researchers to analyze their own collaborative network, as well as possibilities for future collaboration among EWG-DSS members only using a Web-based platform, in anywhere at anytime. The Collab-Net system can be used as two end-users profiles: Administrator and Member profiles.
