Analysis of production planning and control (PPC) systems as an efficient combination of information activities

Production planning and control (PPC) systems with their planning structures, submodules and the information and data processing show similarities with the structures of multistage multi-product manufacturing. So, here the attempt is made on the basis of the activity analysis to integrate the information characteristics of goods involved in production with regard to the requirements of production planning into the input-output relationships and to represent them in the form of so-called ‘informational production functions’. Based on the formulation of information activities efficiency criteria are developed, which allow to evaluate the data processing in PPC-modules and thus to eliminate inefficient activities. A concrete application to dynamic lot sizing demonstrates the procedure.
