A local area network and information management system for a submarine overhaul facility

A preliminary design of a local area network for a submarine overhaul facility is developed using System Engineering concepts. SOFLAN, the Submarine Overhaul Facility Local Area Network, is necessary to provide more timely and accurate information to submarine overhaul managers in order to decrease the overhaul time period and become more competitive. The network is a microcomputer based system following the Ethernet and IEEE 802.3 standards with a server .. client architecture. SOFLAN serves thirty five users at various offices and overhaul facilities throughout the shipyard. The network provides a medium to transmit information between and across various organizations. Applications resident on the network include a database management system, file transfer, word processing and electronic mail. SOFLAN replaces the existing manual systems' currently is use at the shipyard. The system life cycle is twelve years from development to phase-out with a cost over the entire life cycle of approximately two million dollars.
