Research on Lean Manufacturing
Three of the research projects funded by National Shipbuilding Research Program (USA) involve Lean Manufacturing - a manufacturing philosophy, which seeks to reduce overall lead-time from raw material to customer order by eliminating non-value added waste. Quality is built in at the source, rather than inspected in. Processes are highly standardized and timed. The goal of lean manufacturing is to achieve the highest quality, lowest cost, and shortest lead-time. |
World Class Material Standards and Design Rules project draws on the lean manufacturing principle of “takt time” that is, having an equal amount of work at each stage of the assembly line process. To accomplish this, ship construction is divided into blocks with standardization build into each block. This project is attempting to develop standardized basic component and subassembly designs. This will reduce the amount of change to blocks as they are reused in different ship construction projects and will dramatically reduce time and cost, and improve quality. The shipyard begins to resemble a manufacturing facility rather than the craft shops of today. Researchers working on the project have already delivered more than 500 standards for structural details, pipe, electrical, HVAC, and metal outfit. |
