A transport represents the function of a system transferring mass or energy between two systems or locations. A transport function has one upstream and one downstream connection to an influence rela- tion. The downstream connection point is indicated by the arrow head representing the direction of flow. Note that the flow direction is not identical… read more »

Flow functions

In MFM functions are defined in relation to the processing of flows of mass and energy. MFM is based on a set of six generic flow functions representing different primitive operations performed on either mass or energy flow. These six functions are shown in the figure below and include: source, transport, storage, sink, balance and… read more »
