Shipyard Modelling -- Approach to Obtain Comprehensive Understanding of Functions and Activities

The application of Computer Integrated ManufacturingCIM to one-of-a-kind heavy engineering industries is one of todays most challenging tasks for the industry and Information Technology IT vendors. Because of the complexity of the shipbuilding process, as a typical representative of this kind of industry, available solutions are not yet satisfactory. Even the basic theory of current CIM systems does not fit many aspects of requirements for the shipbuilding industry. The application of CIM tools, which are based on ideas of line production and have a strict sequency of all tasks, have very often failed in the past, mainly because of a lack of flexibility. Therefore, basic work needs to be performed, starting with a detailed analysis of todays situation and leading to a careful development for the real requirements of tomorrow. This paper deals with the problems resulting from the exceptional nature of shipbuilding for the application of CIM elements. The approach chosen for modelling of the production process, illustrated by some examples from actual Research and Development RD projects, is described. An evaluation of the benefit of structured shipyard modelling and a look at complementary RD actions concludes the paper.
