1. A system for creating and implementing an installation cleaning process for a process installation, the installation cleaning process being formed as a cleaning-in-place process and the process installation being configured to be cleaned via the cleaning-in-place process, the system comprising:
a processor;
memory which stores process cleaning information;
a plurality of process modules, each process module of the plurality of process modules representing a respective process installation to be cleaned, said plurality of process modules each storing respective self-description information relating to each respective cleaning property, and each process module of the plurality of process modules being configured to transmit or share the respective self-description information;
at least one auxiliary module which provides auxiliary services for the installation cleaning process, the at least one auxiliary module being configured to transmit or share information about respective auxiliary services; and
a second processor which accesses the cleaning process information stored in the memory, said cleaning process information comprising at least cleaning steps which are required for the installation cleaning process and model descriptions of cleaning efficiency for each cleaning step, the second processor being configured to determine an installation-specific cleaning schedule based on the cleaning process information, the self-description information of the process modules, and the information of the at least one auxiliary module;
wherein the process installation is cleaned via the cleaning-in-place process in accordance with the determined installation-specific cleaning schedule; and
wherein the self-description information comprises (i) at least a description of autonomous cleaning sequences, (ii) status information relating to a respective cleaning status and a respective dirt saturation of respective cleaning paths and interfaces of the corresponding process module, the respective cleaning status being utilized to calculate a minimum throughput or flow of at least one cleaning agent on the respective cleaning paths and to calculate a maximum permissible throughput or flow of the at least one cleaning agent to prevent cavitation from occurring, and (iii) material properties comprising surface roughness which have an influence on a cleaning time.
