This contribution attempts to discuss a non-conventional solution for treating the complex Environmental Impact Assessment decision problem. It is typically a complex ill-structured decision making problem that involves: huge quantities of data to manipulate, low quality of data (uncertainty, measurement errors, missing data), different spatial and temporal scales (from seconds to years, from local to global), dynamic and stochastic behavior, and being at the crossroad among many disciplines/domains, and so many qualitative or subjective factors. In addition, the mentioned environmental dimensions often include non-homogenous subsets of input factors or variables. Consequently, in these situations, the decision-making problem becomes so complicated when we need to assess the overall environmental impact of a newly proposed human activity, specifically, we need to decide whether to adopt or proceed with such a project. A binary YES/NO decision problem requires assessing the influences of all non-homogeneous inputs factors within the given relevant environmental dimensions or views. One way to obtain a reliable solution to such a complex, critical decision problem is to rely on the knowledge, heuristics, and experience of different corresponding to each environmental dimension. Our discussion will deal with a modular intelligent environmental decision support system that makes use of fuzzy logics and appropriate human in rigorously assessing the impacts of the proposed or existing project on the surrounding environment or human health. The proposed system includes multiple fuzzy expert systems (FESs), each of which contains the homogenous and aggregated knowledge relevant to one environmental dimension. An objective numerical scale is established to assess the decision outputs of each individual system.
Integrating multiple intelligent decision support systems is particularly useful in obtaining, high quality, more comprehensible, and reliable decision solution. The reasons for independency are justified by easier maintainability, analyzability, context flexibility, decision-making modularity, sensitivity of aggregate knowledge, decision consistency, etc. A consensus-based heuristic will be used as the basic mechanism to combine the outputs of multiple FESs. The heuristic exploits the consensus-relevant information among FESs decision outputs, and is guided by two sets of consensus measures or indicators: similarity-based indicators and weights derived measures. The proposed consensus based heuristic is particularly adequate for the nature of the binary decision problem in which decisiveness is much more required than a compromise. The presented results are general enough in order to improve decision-making process in many other disciplines, as e.g. environmental risk assessment, food quality tracking, etc.
