Engineering-to-Order (ETO) processes in shipbuilding rely heavily on the short lead times of design and engineering information. Co-engineering parties are constantly confronted with the question whether or not to share immature, preliminary information: Working with preliminary information will certainly induce iterations and rework once the information has been consolidated. On the other hand, the time pressure is high and idly waiting for (more definite) information is also risky. The eventual goal of this research will be to obtain improved insights on the overall consequences of delay in engineering activities and to identify the missing information that is often causing such delays. But as an intermediate goal it is required to ‘rewrite’ daily engineering plans into a consistent set of activities, activity relations and resource requirements, opening the door to using more advanced planning algorithms for ETO planning. Therefore a set of patterns and rules was developed to automatically generate an underlying (more intricate) network of sub-activities. From this a consistent critical path planning - for instance suitable for Monte Carlo Simulation - can be generated. For a case ETO project this approach was tested in order to see whether this approach lead to - a valid schedule, - a better schedule (including stochastic information), - better progress reports. The conclusion is that the proposed method is capable of serving as a pre-processor for more advanced planning algorithms. This was demonstrated by executing Monte Carlo simulation to generate ‘stochastic’ schedules and revisions of schedules.
