Business process variability is an active research area in the field of business process management and deals with variations and commonalities among processes of a given process family. Many theoretical approaches have been suggested in the last years; however, practical implementations are rare and limited in their functionality. In this paper, we propose a new approach for business process variability...
Software testing plays a major role for engineering future systems that become more and more ubiquitous and also more critical for every days life. In order to fulfill the high demand, test automation is needed as a keystone. However, test automation, as it is used today, is counting on scripting and capture-and-replay and is not able to keep up with autonomous and intelligent systems. Therefore,...
Simulation experiments are not conducted in a vacuum. They are performed to address specific research questions that require evaluation of testable hypotheses. However, the connections among goals, hypotheses, and experiments are often characterized in an ad hoc manner. In this paper, we examine symbiotic dependencies among goals, hypotheses, and experiments within the context of computational discovery...
The large-scale aggregation and analysis of user opinions is becoming increasingly relevant to a variety of applications, from detecting social mood on some political topics to tracking their sentiment changes related to events. The analysis of diverse sentiments is another important application, which becomes possible based on the ability of modern methods to capture sentiment polarity on various...
User modelling is an old research discipline. The main concern of this discipline is to improve the quality of human-computer interaction predictive goals, preferences and context. Thus, adaptation and personalization of a document or an application for a particular user need to have information on the latter. It often referred to as “user profile”. A user profile modelling process must be done in...
There is little understanding of how and on what grounds people perceive or group Social Media Platforms (services) in which they participate into categories that can explain or predict their patterns of use. Some models are discussed and the possibilities of an ecological model are highlighted. This study examined how active users grouped social media platforms. 59 respondents completed an open card...
IT environments that consist of a very large number of rather small structures like microservices, Internet of Things (IoT) components, or mobility systems are emerging to support flexible and agile products and services in the age of digital transformation. Biological metaphors of living and adaptable ecosystems with service-oriented enterprise architectures provide the foundation for self-optimizing,...
This paper presents the SIEGMAS system (Stakeholders Interactions in Environmental Governance by a Multi-Agent System) designed to simulate interactions between stakeholders in common pool resources in Indian Ocean Islands. This decision support system tool is based on a model allowing the study of the interactions between agents acting on a territory and influenced by economic aspects thanks to an...
In [10] and [16], we proposed tools for simultaneous variable selection and parameter estimation in a functional linear model with a functional outcome and a large number of scalar predictor. We call these techniques Function-on-Scalar Lasso (FSL) and Adaptive Function-on-Scalar Lasso(AFSL). A scalar group lasso was used to fit the FSL and AFSL estimates. While this approach works well, we improve...
Requirements engineering is a most critical activity in the engineering process of complex cyber-physical systems. To avoid the ambiguity of natural or semi-formal languages, to provide tool support for engineering activities all along a system lifecycle (from scoping studies to system operation, maintenance), EDF has developed FORM-L, a formal constraints-based language for the modelling of assumptions,...
Applications that can use information obtained through device sensors to alter their behavior are called context-aware. Design and development of such applications is currently done by modeling the application's context or by using novel requirements engineering methods. If the application is to support the user's well-being, these methods fall short due to their technical focus. We propose a model-driven...
Agent Based Modeling and Simulation (ABMS) is considered an effective approach for conducting simulation studies in many fields. In order to develop high quality simulation models, methodological approaches are demanded. In such direction we are moving by proposing a heuristic for the formalization of agent based simulation problems. The proposed heuristic is based on some guidelines developed for...
Small and medium enterprises (SMEs) are often described as the engine of growth for a country's economy due to their significant economic contributions. At the same time, ebusiness offers an opportunity for SMEs to significantly further their growth as it has been identified as a tool that could improve an enterprise's operational efficiency and competitiveness in the global market. Despite the promised...
Biological systems provide an exceptional source of inspiration for the design of autonomous adaptive agents. In this work, we propose ICE (or Information-Computation-Evolution), a new bio-inspired agent model for complex, multiagent self-organized systems, such as biological or social systems. The model proposes a physical organization of reality using three main components — information organization,...
Cyber-Physical-Social Systems (CPSSs) integrate various resources from physical, cyber, and social worlds. Efficient interaction of these resources is essential for CPSSs operation. Ontologies do not only provide for semantic operability between different resources but also provide means to create sharable ontology-based context models specified for actual settings. Usage of the context supports situation-driven...
i∗ is a goal-oriented and agent-oriented modeling framework that focuses on the analysis of intentional and strategic relationships among actors. In this mini-tutorial, we highlight a number of recent applications in practical industrial and business settings.
UML profiles are a frequently used alternative to describe the abstract syntax of modeling languages. As any abstract syntax, UML profiles evolve through time. As UML profiles are used for models definition, their evolutions may have a direct impact on them. The adaptation costs of these models may be as important as redefining a complete new model from scratch. In this paper, we deal with reducing...
This paper introduces a computational model for contagion and change of habitual behaviour in a social network. It considers both the level of individual mechanisms of habit formation, involving a person's attitudes, goals, intentions and relevant environmental cues, and the level of social mechanisms for the impact of others in a social network. Simulation experiments with the model for small-world...
This communication presents the genesis and the implementation of a Teacher Module, which is included in an Assistance Tool Software (ATS). The aim of the ATS is to help a teacher to design pedagogical devices. For that purpose, a Teacher Module (TM) collects data about the teacher and his/her teaching context. The ATS uses these data to adapt the device to the teaching context and to the teacher's...
