Introduction of a production planning and control system (PPC) in an Austrian foundry [2.11 mb]
Zusammenfassung (Englisch)

The selection of a PPC-system is a long-term decision which defines the enterprise frequently ten to fifteen years. In this time a company will change itself radically in its structure and its production kind. A PPC-system must be improvement-capable for that and be able to adjust with small expenditure onto the respective requirement because otherwise the danger that developments are slowed down exists (because the PPC does not approve that). A phenomenon which is to be found (unfortunately) very often. For that the planning and data preparation phase (in which the examined enterprise is currently) of the introduction of a PPC-system (next to a professional implementation phase of the users) represents the by far most important section. Often the technical realization of requirements is put, however, into the center - without an efficient organization of the existing processes and the creation of a high user acceptance a perfect technical solution becomes however (as already thousands times occurred) to be condemned to the failure from beginning. It is to improve established work and thinking manners, as well as to use the "IT- technical-restart" for the adjustment of the available databases. Data are taken over frequent from old systems as e.g. calculation or old PPC-systems. These data are almost always inadequate. If a new system is introduced with higher requirements onto the accuracy, onto the informative capability and onto the reliability, the data must correspond to theses new requirements then. The examined enterprise represents a classical representative of the "old economy" - it is active in the field of the heavy casting. It is very "traditional" organized - what is reflected very clearly in the existing processes and the working methods. The manufacturing is "workshop"-based: From a product only few pieces which have a very long machining time (up to a year) are produced. These factors built the base for the decision to implement an individual solution that can be fit exactly to the requirements of the enterprise. The first phases of the planning/implementation of this PPC-system are described within this thesis.
