<p>A methodology for the creation of decision support systems (DSS) from mathematical programming models is      examined. This approach is demonstrated using a model for flight scheduling, integrating a formal data model,      represented in a database management system (Paradox), and a mathematical programming model, represented      in an executable mathematical modeling language (GAMS). The integration is completed by creating a database      capable of supporting the GAMS model creating a series of queries to extract the data required by the GAMS      model, and finally by modifying the GAMS model to import the external data sets and write the results to a file      that can be interpreted by the database. This process is first completed manually to support a specific GAMS      model. In the second portion of this thesis, the process is generalized to provide a framework that can be used      to design a front-end database for any GAMS model. Benefits of this integrated approach over using a stand      alone mathematical model include: The assurance of model integrity, explicit data modeling, improved      representation and manipulation of model inputs and outputs, greater integrity of input data, and easier      interpretation and multiple views of model outputs.
