On large Computational Grids, performance is one of the main problems that has to be addressed but another important issue is the underlying interconnection network that has to be reliable in order to ensure the nodes' intercom-munication and the migration of the appropriate load from one node to others. Reliability and performance are both influenced by(More)
This work is devoted to the portfolio project management problem and more specifically is focused on IT portfolios' management. This problem is formulated as Resource Constrained Scheduling Problem (RCPSP). The contemporary organisations such as the IT companies plan and execute a set of projects that share common resources. Therefore, each IT organisation(More)
This paper proposes a consolidation of the Incremental Funding Method (IFM) with the Job Shop Scheduling Problem (JSSP) through Neural Networks, in order to develop a model for software projects. More specifically, it formulates the IFM method in terms of JSSP model and then gives a solution method based on Recurrent Neural Networks (RRNs). The IFM is a(More)
This paper proposes a Neural Network approach for the project portfolio management problem. The modern organizations such as the IT firms schedule and perform a set of projects that share common rare resources. Therefore, each IT organization develops a set of IT projects and it has to execute them simultaneously. In this work we reviewed the literature and(More)
The project portfolio scheduling problem has become very popular in recent years. Current project oriented organisations have to design a plan in order to execute a set of projects sharing common resources such as personnel teams. These projects must, therefore, be handled concurrently. This problem can be seen as an extension of the job shop scheduling(More)
The Incremental Funding Method (IFM) in software development projects aims at optimizing the financial return of a software project through proper sequencing of development activities and incremental releases of the software product. This paper presents a Dynamic Programming (DP) project scheduling algorithm that maximizes a software project's net present(More)
