Decision model based on analytical hierarchy process for managing the environmental risks within the environmental management systems

The environmental protection issue at the national level and within organizations is very complex, due to a multitude of involved factors. To take the most appropriate decisions in normal/critical situations, a series of methods of analysis have been elaborated and implemented. The work presents the Analytical Hierarchy Process - English acronym AHP - as a multi-criteria decision instrument for modeling the preferences representations. This methodological instrument, special dedicated for environmental group decision in the field of environment, is a useful one in the process of decision taking, making it less prone to the subjectivity of value judgments by using a set of prior consensual agreed relevant criteria. The proposed decision model helps decision-makers to highlight the hazards of different planned and unplanned pollutants discharges and to assess the possible environmental risk due to the significant pollution evolution in the context of organization site conditions.
