The AEPEIS program is a computerized capability to make a quantitative assessment of the total environment, based on functional dependencies between natural or cultural processes and the natural or cultural influences which impact those processes. The program uses sets of matrices, where the XYZ axis (the ordinate) consists of the processes; the ABC axis (the abscissa) consists of the influences; and the A/X intersect, for example, is defined as the functional dependence of X process upon A influence. The AEPEIS system has been developed to its present state in the field of biology, where each biotic process such as metabolism, on the XYZ axis, has a functional dependence upon abiotic influences on the ABC axis. AEPEIS is also applicable to chemistry, physics, geology, economics, and all the social and physical sciences that contain bodies of knowledge or sets of data relevant to environmental impact statements, such as physical oceanography, meteorology, sociology, authropology, medicine and jurisprudence. Fuctional dependencies, as identified through matrix intersects such as A/X, B/X, etc., are analyzed on sets of matrices through successive biotic levels as necessary to evaluate the total impact of the proposed action. For example, the assessment can start with a matrix designed for cellular level of cellular level of analysis and progress systematically upward through an entire set of matrices designed for individual, population, community and ecosystem levels; or it can go into the problem at the community or other level and progress downward or upward as necessary for a complete appraisal. Several examples of such matrices are presented and discussed.
