Risks and Operational Research. The new challenges based on the approaches used

Abstract

One of the concerns in public and private sectors that remains over the time is the timely identification of situations that destabilize the main objectives of organizations. Invariably, the first step in any risk assessment methodology is the identification of the risks and this should be done meticulously. In this paper, we analyze several approaches that have been addressed for the identification or risks arising from the past, the current approaches and the needs for the future. These necessities show the challenges in tools, and methodologies. This paper also presents a methodology of complex systems as an alternative to address the problems of the determination of many factors, the interdependences between them, and the operations research techniques that exist.
