Group Technology or Zone Logic Technology has been successfully implemented in severe U.S. shipyards for new ship construction. This technology was originally conceived in the U.S. It was greatly refined by the Japanese and recently beginning on 1978 reimported to the U.S. The technology replaces traditional system- by-system work with work organized zone-by-zone end by grouping similar work together with zones. This grouping of jobs enhances efficiency. Those yards in Japan where Zone Logic is an everyday way of working, find that this technology is very effective in large scale overhaul and modernization projects covering both alterations as well as repairs. The traditional approach of working by systems is difficult to manage with the degree of difficulty being proportional to the size of the project. Work performed utilizing the principles of Zone Logic provides a more effective management method. The application of Zone Logic to Ship Overhaul, as advanced by Zone Logic advocates, has actually been made in small isolated cases.
