Isaias José Badillo-Piña, Ricardo Tejeida-Padilla, Oswaldo Morales-Matamoros

Abstract


The Viable System Model (VSM) is recursive and helps explaining the general production management model of the ERP system. The recursion level explains the development starting from warehouse management to Material Requirement Planning (MRP), to Manufactory Requirement Planning (MRPII), to Enterprise Resources Planning (ERP), and to Supply Chain Management (SCM).

In each recursion level, the emergent concepts helps explaining the discovery of the two categories of demand: independent demand and dependent demand, the feedback concept helps explaining the closed cycles in ERP, the local, future and total environment concept helps explaining the interactions between the market and the Production System and the Law of requisite variety helps to manage complexity.
