Abstract

Procedures describing a start-up sequence for modern process plants consist of a sequence of actions and checks which are often rigid and do not allow for deviations from predefined courses of action. When a plant is viewed as a collection of functions supporting either each other or the top-level goals of operating the plant, a start-up may be seen as the task of establishing these functions. For this purpose task descriptions centred on the establishment of functions have been developed, based on the multilevel flow modelling (MFM) methodology. By focusing on the functional aspects of the physics of the plant, the same model may be used for the diagnosis of faults, explanation of consequences and planning of start-ups. A description of how the MFM methodology can be extended so that knowledge from the model can be transformed into task descriptions suitable for automatic construction of start-up sequences is given, and feasibility validation of the plan constructed by the operator is provided.
