Multi-agent systems Virtual organizations Pervasive Systems Model-Driven Development The development of Ubiquitous or Pervasive Systems can be considered a complex task, with multiple actors, devices and different hardware environments; where it is difficult to find a compact view of all the components. This work proposes to use a MDD (Model-Driven Development) approach to facilitate the develo...

Two new multiprocessor architectures to accelerate the simulation of multi-agent systems based on the massively parallel GCA (Global Cellular Automata) model are presented. The GCA model is suited to describe and simulate different multi-agent systems. The designed and implemented architectures mainly consist of a set of processors (NIOS II) and a network. The multiprocessor systems allow the i...

This paper investigates the influence of the length of the lease period on the maintenance policy for leased equipment with residual value. The length of the lease period increases, however, the lessor’s income increases, and the maintenance cost of the equipment rises as well. Therefore, the lease payment and maintenance service of the equipment are crucial items in the lease contract for the ...

This note contributes to the discussion of decision problems with imperfect recall from an empirical point of view. We argue that, using standard methods of experimental economics, it is impossible to induce (or control for) absent–mindedness of subjects. Nevertheless, it is possible to test Gilboa’s (1997) agent–based approach to games with imperfect recall. We implement his model of the absen...

In design science research in information systems (DSRIS), validation is often neglected in exchange for an emphasis on evaluation. However, rigorous scientific contributions most often explicitly address validation. In order to address the complexity of validation within design science, an explicit recognition of the assumptions and methods used within the DSRIS framework is needed. In this pa...

Religiosity is one of the most important sociological aspects of populations. All religions may evolve in their beliefs and adapt to the society developments. A religion is a social variable, like a language or wealth, to be studied like any other organizational parameter. Several questions can be raised, as considered in this study: e.g. (i) from a " macroscopic " point of view : How many reli...

Executive Summary Human error will pose a threat to the operation of Unmanned Aerial Vehicles (UAVs), just as it does in other fields of aviation. If UAVs are to be permitted to operate in the National Airspace System (NAS), it will be necessary to understand the human factors associated with these vehicles. Rather than eliminating the potential for human error, the removal of the on-board pilo...

Redundancy technique is known as a way to enhance the reliability and availability of non-reparable systems, but for repairable systems, another factor is getting prominent called as the number of maintenance resources. In this study, availability optimization of series-parallel systems is modelled by using Markovian process by which the number of maintenance resources is located into the obje...

since lean concept has appeared many works have been done on decreasing or even eliminating of wastes such as extra inventory. although these studies have not taken into account expected availability seriously. so in this paper, a multiple objective decision making (modm) model has been developed by viewpoint of these subjects. they are decreasing wastes and increasing system availability. wast...
