Steel Hull Shipbuilding Cost Structure Semantic

This study analyses the cost structure of the several processes associated with the shipbuilding industry.The analysed productive processes are the cutting preparation procedures; the several steel plate cutting processes; the processes of hull plates and stiffeners forming; the associated transport and assembling of plates and profiles; and finally the welding processes. VALUE STREAM MAPPING METHODOLOGY FOR PREValue stream mapping is used to identify the wastes in industrial processes of many industries such as the automotive and aerospace.In order to remain competitive in the shipbuilding industry it is necessary to continually work on reducing waste in production processes.A clear-cut methodology for shipbuilding is lacking.Since steel makes up the most significant weight composition of
