1. A system having at least one plant system having at least a plurality of agents, having at least a plurality of autonomous mobile robots, movable machinery, and a plurality of sensors for generating data for use in the safety relevant securing of the plant system,
wherein a local plant safety system associated with the plant system is present;
wherein data of the local plant safety system are stored in a first database;
wherein the local plant safety system has a first data model with data sets of the plant system;
wherein a decentralized public plant library system associated with the local plant safety system is present;
wherein the plant library system is stored in a second database;
wherein the plant library system has at least one second data model having at least data sets for the plant safety system;
wherein the plant safety system and the plant library system are connected to one another via an interface, with data and data sets being transferable between the plant safety system and the plant library system via the interface;
wherein the datasets respectively comprise at least a geometry, a hazard, a safety level, a position, a speed, an identification, and a measure,
wherein the plant safety system is configured to carry out a risk assessment and a risk evaluation for the plant system cyclically or after determining a change and to make decisions on a necessity of a risk reduction cyclically or after determining a change, whereby the plant safety system is configured for an automatic and dynamic preparation of a risk evaluation of the plant system;
wherein the plant library system is configured to read applicable standards and regulations and the plant library system is configured to carry out the automatic and dynamic preparation of the risk evaluation on the basis of the applicable standards and/or regulations,
wherein the autonomous mobile robot is configured to react locally with collision avoidance as part of a risk reduction procedure;
wherein the plant safety system is configured to inform the autonomous mobile robots that are in the environment of the changes of the real situation in comparison with a digital twin of the change;
wherein the plant safety system is configured to check whether the changed situation is an already classified risk;
wherein the autonomous mobile robots are configured to update the corresponding datasets if the risk has already been classified;
wherein the plant safety system is configured to look for a suitable risk and dataset in the public library level on the plant library system if no classified risk and thus no dataset is present on the plant safety system for the new situation;
and wherein the plant library system is configured to take over a new classified dataset that has been created by experts by means of a risk analysis if no correspondingly classified dataset is present on the plant library system.
