Abstract: Most decision making models deal with selecting an optimal alternative. Researchers have noticed the failure of these models in dealing with real-world problems. This suggests that existing models are not entirely adequate for the needs of decis ion makers, and there is a need for model structuring that considers behavioral aspects in an in-depth inquiry of the decision situation. Realizing these difficulties, new paradigms have been proposed. Researchers argue that some of the difficulties are due to conflicting objectives. However they still face the inherent difficulty of solving multi objective models. Several decision making methods focus on structuring although selection is still the end result and goal of a decision-making process. It is reiterated here that decision makers need assistance in attaining two further goals : COMPREHENSION of preferences and GENERATION of elusive alternatives. In other words, the goal is not to select an alternative but to comprehend and generate. To achieve it an "objectivesubjective structure" is presented as the core of a process. Its main components are sets of alternatives, attributes and criteria. The process is about identifying these and establishing two relationships: an objective mapping from alternatives to attributes and a subjective mapping from attributes to criteria. These relationships imply a certain complexity inherent in decision making regarding the acquisition of information. The first mapping relates to information about the external world and the second to the decision maker's inner world. We apply these concepts to a private logging firm dealing with environmental issues. It became clear that the decision variables did not exhaust the full spectrum available; that the firm is not yet in a position to make “environmental decisions”; that there are other players; and that strategic decision variables exis t. The firm has recognized that environmental issues impose strategic planning for the long term and that it is necessary to develop appropriate attributes to measure the criteria.
