Information Management Systems and Expert Systems enable asset managers to maximize the use and value of the information available. The challenge in the asset management field is usually to combine multiple sources of information and specialized applications, such as Pavement Management Systems (PMS), into the decision making process without affecting the reliability of the analysis nor the evolution and update of information stored. When several systems and different types of assets are involved in the decision making process, the complexity of the analysis is considerably increased. That is why we need a structured and integrated approach.
