Despite the need for model use and management in organizations, a small number of decision makers use some tool for that purpose. Some reasons for this paradox are model complexity and the lack of a friendly environment for model construction, testing and management tailored for decision makers. In this work, we present GMMS (Graphical Model Management System), a graphical environment in which decision makers can formulate, manage and execute models in a simple and straight fashion. The environment provides support for SML (Structured Modeling Language), a model definition language, and for SQL-M, that is an SQL (Structured Query Language) extension for model management. Both languages are used through an easy to use graphical language. Models are created visually by dragging and dropping icons from a modeling palette, and model instances are created using an wizard thathelps the decision maker along the process. Models are executed by using solvers external to the environment, in a way that is fully transparent to the decision maker. GMMS provides a friendly and easy to use environment where decision makers can play with models without having a deep technical knowledge on model management. This leaves spare time to get more concentrated on the problem and its domain.
