IPSEpro covers the entire lifecycle of a process plant with its two major configurations: the Design Suite and the Plant Operation Suite. IPSEpro has a modular structure, so that the requirements of a specific installation can be taken into account.
PSE is IPSEpro's Process Simulation Environment. With PSE you create a process model based on components from a specific IPSEpro library.
MDK, IPSEpro's Model Development Kit, is a programming environment that offers all the capabilities required to define and build new component models.
