1. A production plant (2) of the metal production industry, the non-ferrous or steel industry or master alloy manufacture, comprising:
a production planning system (3) for determining a production sequence for the production plant (2) including control data for an automation system (4);
the automation system (4) for controlling production in the production plant (2), wherein the automation system (4) executes the production sequence determined by the production planning system (3);
a state monitoring system (5) for acquiring states of the production plant (2) and its components,
wherein the state monitoring system (5) provides a prediction of states of the production plant and its components;
a business planning system (6) for economic management of production and maintenance in the production plant (2),
wherein the business planning system provides economic information relating to one or more of material purchasing, resource purchasing, spare parts procurement, spare parts management, delivery costs, delivery times, storage costs, and personnel costs; and
a maintenance planning system (1), wherein the maintenance planning system (1) is designed to determine maintenance measures for the production plant (2), including
a listing of the maintenance measures to be carried out,
a listing of items required for the maintenance measures to be carried out,
a listing of persons and/or equipment involved in the maintenance measures,
a schedule for the maintenance measures to be carried out, and
a listing and/or execution of orders for operating resources and spare parts,
wherein the maintenance planning system (1) creates a digital model (8) of the production plant (2),
wherein the digital model (8) is a digital twin of the production plant (2) and comprises information of the production planning system (3), the automation system (4), the state monitoring system (5), and the business planning system (6),
wherein the maintenance planning system (1) by the digital model (8) optimizes the maintenance measures with regard to an economic utilization of the production plant (2) in order to dynamically adapt an overall economic balance of the production plant (2) with respect to maintenance to a current load situation and a near future load situation,
wherein the digital model (8) associates the following information to determine the maintenance measures:
the determined production sequence of the production plant (2) of the production planning system (3),
the control data of the automation system (4),
the acquired states of the production plant (2) and its components, and
the prediction of states of the production plant (2) and its components of the state monitoring system (5) and
the economic information of the business planning system (6).
