In previous work [1] we presented a framework for the specification of open computational societies i.e. societies where the behaviour of the members and their interactions cannot be predicted in advance. We viewed computational systems from an external perspective, with a focus on the institutional and the social aspects of these systems. The social constraints and roles of the open societies ...

The scheduling and execution of bag-of-tasks applications (BoTs) in Clouds is performed on sets of virtualized Cloud resources that start being exhausted right after their allocation disregarding whether tasks are being executed. In addition, BoTs may be executed in potentially heterogeneous sets of Cloud resources, which may be either previously allocated for a different and fixed number of ho...

In modern day wireless networks, spectrum utilization and allocation are static. Generally, static spectrum allocation is not a feasible solution considering the distributed and dynamic nature of wireless devices, thus some alternatives must be ensured in order to allocate spectrum dynamically and to mitigate the current spectrum scarcity. An effective technology to ensure dynamic spectrum usag...

The Virtual Secretary 2 project (ViSe2) focuses on the construction of a multi-agent cooperation system. As a research vehicle, we have chosen to build intelligent agents that perform secretarial tasks for their users either by themselves or via cooperation. An individual ViSe2 agent has limited knowledge and problem-solving capabilities. To act better for its user, the agent interacts with oth...

To meet the requirement and solve the problems in system integration field, A Federation Structure based Multi-Agent System (FSMAS) model is proposed in this paper, with emphasis on the collaboration algorithm. This paper presents the process of partition and collaboration of the Agent tasks, the acquaintance first based on CNP algorithm in collaboration. FSMAS is applied to the development of ...

The user interface is a crucial part of most computer applications. Specially in complex applications, the user interface very often determines the acceptance or the rejection of a program by the user. The design of graphical user interfaces for multi-agent systems is specially difficult due to the particular characteristics of these systems. This difficulty is even greater when we consider the...

Artisanal gold mining plays an important role in sustainable development of rural communities. The objectives of this study were to: i) assess the environmental impacts of recent artisanal gold mining activities in Chimanimani National Park (CNP), eastern Zimbabwe, and ii) discuss the associated implications of artisanal gold mining to sustainable development in the Chimanimani area. Data were ...

Agent-based modeling is a promising approach for developing simulation tools for natural hazards in different areas, such as during urban search and rescue (USAR) operations. The present study aimed to develop a dynamic agent-based simulation model in post-earthquake USAR operations using geospatial information system and multi agent systems (GIS and MASs, respectively). We also propose an appr...

To reduce complexity, we base our system on alliances—a set of agents that agree to share some private information and eventually cooperate. In CPlanT, each agent represents a complex, organized entity—such as a non-governmental organization (NGO), humanitarian organization, or army unit— that plays an active role in mission planning. These agents group themselves in various, temporary coalitio...

Agent-based software technology plays an important role in the manufacturing industry for achieving agility. Shop floor control applications can be designed based on the paradigm of agent negotiation to cope with variabilities and disturbances in the production environment. This often involves the contract net protocol (CNP) and previous research has suggested that the timing parameters of CNP ...
