Abstract
Analyses of solutions for large-scale optimization models are very difficult without effective computer aids. Solution reports may require weeks to design, implement and produce with conventional report writing systems. The reports produced are voluminous, often exceeding 100,000 printed lines, and are thus quite awkward to access manually. Timely and economic analysis of solutions to large models is further hindered by inflexible and costly report writing software and procedures. ATHENA has been developed to allow extremely efficient immediate interactive storage and analysis of the solution file from any optimization system. ATHENA is easy to learn and use; user friendly features are provided which can preemptively assess the potential cost and implications of each request for solution information, assist the confused user, and provide the required solution information with very fast response time. The user is provided with extensive search under mask and compound logical relational constructs, as well as the capability to quickly diagnose suspicious model symptoms, and to format and issue offline reports. ATHENA is implemented in portable FORTRAN, with a parser and interpreter easily modified and expanded to suit particular hardware environments and user demands. The system has been initially designed and tuned for large-scale problems with up to 30,000 rows and columns. Live test demonstrations show that the system exhibits very fast response time in actual use. This report presents a users manual for the prototype ATHENA query language, an error message directory, and a description of interface and extension provisions
