Nurse Rostering is a combinatorial problem hard to solve due to its size and complexity. Several real world details that arise in practice make computerized approaches to the problem indispensable. The specifications of the problem that we solve are those defined in the Nurse Rostering Competition INRC2010. In this contribution, we solve the Nurse Rostering(More)
In this paper, a detailed model and an efficient solution methodology for the monthly workshift and rest assignment of hospital nursing personnel is presented. A model that satisfies the rules of a typical hospital environment based both on published research data and on local hospital requirements is designed. A hybrid methodology that utilizes the(More)
A computer program can be represented by a Directed Acyclic Graph (DAG) in order to capture the dependencies between the individual tasks that should be executed each time the program runs. This paper proposes a mathematical model of Integer Programming that can be applied in order to schedule the tasks in the presence of multiple processors serving as the(More)
This paper describes the ERMIS system, specially designed to support the fleet and personnel scheduling and management issues, as well as to support various business collaboration issues for a helicopter taxi company. The implemented system offers a Web-based interface for the flying and stationary personnel and a software application running on a PDA with(More)
The expression of parallelism in commonly used programming languages is still a large problem when mapping high performance embedded applications to multiprocessor system on chip devices. The Architecture oriented paraLlelization for high performance embedded Multicore systems using scilAb (ALMA) European project aims to bridge these hurdles through the(More)
As processors and systems-on-chip increasingly become multicore, parallel programming remains a difficult, time-consuming and complicated task. End users who are not parallel programming experts have a need to exploit such processors and architectures, using state of the art fourth generation of high programming languages, like Scilab or MATLAB. The ALMA(More)
There is an increasing need for automatic tools and techniques for application parallelization. Within the ALMA toolset, programs written in Scilab are automatically parallelized for execution on embedded multicore platforms. In this paper, key parts of the coarse grain parallelism optimization are presented. The coarse grain parallelism optimization(More)
