Development of an optimised maintenance model for a chemical multi-purpose plant under changing production contexts

The second group was interviewed using a questionnaire as well. Production managers were asked open questions in order to describe the current situation and their perception of their environment from their point of view. With both series of interviews after each interview additional information that was given by the interviewees was noted as remarks. This additional information was of a qualitative nature. The results of the interviews, existing knowledge from academic and other reliable sources and legal regulations were used to answer the research question and to form a specific maintenance model for chemical multi-purpose production plants. Its optimisation was achieved using the main synergies between the individual elements of the research. This project contributes to knowledge with the development of a specific maintenance model that shows that general statements and maintenance concepts (as are available on the market) cannot be implemented without being critically investigated and specifically adapted. Industry-specific properties require specific maintenance concepts. Secondly, it was shown, that the stronger involvement of the operational and workshop personnel leads to a significant, sustainable and long-term improvement of plant operation. The developed maintenance model supports managers to find the best solution for their plant.
