Translating MFM into FOL: towards plant operation planning
  This paper proposes a method to translate multilevel flow modeling (MFM) into
a first-order language (FOL), which enables the utilisation of logical
techniques, such as inference engines and abductive reasoners. An example of
this is a planning task for a toy plant that can be solved in FOL using
abduction. In addition, owing to the expressivity of FOL, the language is
capable of describing actions and their preconditions. This allows the
derivation of procedures consisting of multiple actions.
