AUTOMATED/CONTROLLED STORAGE FOR AN EFFICIENT MBOM PROCESS IN THE SHIPBUILDING MANAGING THE IoT TECHNOLOGY

摘要

Non automated/controlled warehouse sets a possible improvement point in several shipyards. Material arrives into shipyard in stock-trucks or ships, and it is randomly stored when a tight time is set. Material stock orders are saved in the Shipyard storage control System, but there are no link between orders and the real arrived material. MBOM production working orders are based in material available in warehouses, new arriving material sets an availability to start processing this order, but sometimes, MBOM material preparation request more time than expected. Setting an arrival sorting and tag process, with some special marking methods could help to improve material control, availability and processing for these MBOMs. This also increases the material availability time in the Shipyard Storage control System, but it reduces material processing for the next steps of the ship production. Another problem is that, in tight schedules, material collection could be too much, so extra material represents unnecessary purchases. Some material requires a three month request to be served to shipyard. This period gap sets a delay to adjust the real required material to the available in the shipyard, to avoid this delay impact, shipyards try to request in advance more material than real needs, in order workshops don't decrease their work-load. Second problem must be resolved using the CAD and PLM Systems in order to help engineers generating a fast-close-to-real material collection prevision, using special pre-collection of information and helping designers to improve the 3D model.
