The software assets that an enterprise applies toward the management of its business processes are bound to evolve in response to business model transformations dictated by changing management environments. Both a given set of software and its associated data form an asset portfolio that needs to be well managed to generate the greatest possible return over time. Tradeoffs between the TCO (Tota...

Abstract—This paper seeks to give a general idea of the universe of project portfolio management, from its multidisciplinary nature, to the many challenges it raises, passing through the different techniques, models and tools used to solve the multiple problems known. It is intended to contribute to the clarification, with great depth, of the impacts and relationships involved in managing the p...

In general, underground spaces are associated with high risks because of their high uncertainty in geotechnical environments. Since most accidents and incidents in these structures are often associated with uncertainty, the development of risk analysis and management methods and prevention of accidents are essential. A deeper recognition of the factors affecting the implementation process can p...

Selection of new projects is one of the major decision making activities in any company. Given a set of potential projects to invest, a subset which matches the company’s strategy and internal resources best has to be selected. In this paper, we propose a multicriteria model for portfolio selection of projects, where we take into consideration that each of the potential projects has several usu...

In this paper, 1 will describe examples of state-of-the-art practice in supply-chain management; e.g., vendor-managed inventory, quick response, and other contemporary systems, such as Wal-Mart's RetailLink. The perspective will be that of what I call the JDJB Portfolio; i.e., what Information (I), Decision-Making {D), Implementation (I), and Buffer (B) systems are employed in managing real-wor...

A multiobjective binary integer programming model for R&D project portfolio selection with competing objectives is developed when problem coefficients in both objective functions and constraints are uncertain. Robust optimization is used in dealing with uncertainty while an interactive procedure is used in making tradeoffs among the multiple objectives. Robust nondominated solutions are generat...
