Models a fluid reservoir system using the current version of BIOMOD, an interactive computer-graphics system for biological modeling. The BIOMOD system features interaction with immediate feedback, hierarchical model structuring, and user-oriented model-definition languages. It operates on an interactive graphics console comprising a CRT screen, a RAND Tablet, and keyboard. The user may draw block diagrams, handprint or type text, push displayed "buttons" to initiate certain actions, and move labels. He may represent a model by a block diagram, each component of which may be defined by another block diagram. This facilitates devising complex models one portion at a time. When BIOMOD is completed, the user may define model components by chemical equations, differential equations, or data curves, rather than having to translate his model description into a conventional simulation language. During model simulation, the user may display curves for different variables, change scales, or alter simulation parameters. 41 pp. Ref.

This report is part of the RAND Corporation paper series. The paper was a product of the RAND Corporation from 1948 to 2003 that captured speeches, memorials, and derivative research, usually prepared on authors' own time and meant to be the scholarly or scientific contribution of individual authors to their professional fields. Papers were less formal than reports and did not require rigorous peer review.
