This paper deals with the problem of scheduling the mixed workload of both homogeneous multiprocessor on-line and off-line periodic tasks in a critical reconfigurable real-time environment by a genetic algorithm. Two forms of automatic reconfigurations which are assumed to be applied at run-time: Addition-Removal of tasks or just modifications of their(More)
Several real-time embedded system must be dynamically reconfigured to account for hardware/software faults and/or maintain acceptable performances. Depending on the run-time environment, some reconfigurations might be unfeasible, i.e., they violate some real-time constraints of the system. In this paper, we deal with the development of dynamically(More)
The paper deals with the purpose of one hybrid approach for solving the constrained two-dimensional cutting (2DC) problem. The authors study this hybrid approach that combines the genetic algorithm and the Tabu search method. For this problem, they assume a packing of a whole number of rectangular pieces to cut, and that all cuts are of guillotine type in(More)

This research work deals with Reconfigurable Uniprocessor embedded Real-Time Systems to be classically implemented by different OS tasks that we suppose independent, synchronous and periodic in order to meet functional and temporal properties described in user requirements. We define in the book chapter two forms of automatic reconfigurations which are(More)
This paper examines the problem of scheduling the mixed workload of both sporadic (on-line) and periodic (off-line) tasks on uniprocessor in a hard real-time environment. The authors introduce an optimal earliest deadline scheduling algorithm to optimize response time while ensuring that all periodic tasks meet their deadlines and to accept as many sporadic(More)
This paper deals with the study of information technologies and approaches to solve problems related to the automation of selective monitoring on the base of university training and research satellite receiver teleport. Indeed, the utilization of satellite TV technologies at all scientific research and educational process stages could be called a new(More)
