The combination of increased training tempo due to military base closures and the reduction in military budgets have placed a severe burden on the infrastructure at many military installations and emphasized the need for an integrated facility management support system. This research involved linking existing facility, environmental, and operational data within an off the shelf portable geographic information system (GIS) to produce an integrated facility management support system. Presently, no known military installations have an integrated facility management support system linking these systems together within a GIS. An unconstrained theoretical model was first developed using a flowchart logic network to design the system. A detailed application model was then developed using Field Notes as an application model portable GIS package, and Camp Rilea, Oregon, as the application model military installation. The application model was then tested on the military installation at Camp Rilea, to validate the theoretical concept behind the system. The testing conducted on the integrated facility management support system demonstrated the potential for improving the efficiency of facility management operations, and assisting in the prevention of carrying capacity threshold violations on military installations. The results of this research allow for possible implementation of an integrated facility management support system at Camp Rilea and other military installations in the State of Oregon, and the U.S. Army at large. / Graduation date: 1998
