Zusammenfassung
Material flow analysis (MFA) describes a class of methods that allow analysing and designing
material and energy flow systems like supply chains, eco-industrial parks or production sites.
Material flow networks are one of the methods in the field of MFA. Based on the Petri nets, the
material flow network make it possible to conduct static MFA (steady-state modelling) as well as
dynamic MFA (continuous and discrete-event simulation). In this contribution focus will be on the
important building blocks of material flow networks: transitions. Transition specifications can be
regarded as parameterized sub-models, which may exhibit nonlinear behaviour. Linear transition
specifications that consist of fixed production coefficients are always not adequate to represent the
sub-models. In the following a more powerful equation-based approach to process flowsheeting is
discussed. The equation-based approach makes it possible to specify a transition with aid of a
system of non-linear algebraic equation including parameters, design specifications and loops.
