Schedule management system

A schedule management system comprising a plurality of production facilities for producing cell culture products on the basis of a plurality of production processes for producing the cell culture products and a main control device configured to manage the plurality of production processes and manage a cell culture product production schedule made of the plurality of production processes, wherein

• the plurality of production processes comprises a plurality of sub-processes, and in required sub-processes, a production status is determined by determining a quality of a cell culture product being produced;
• the main control device is configured to update a first production process by adding a new sub-process to the first production process or by deleting an existing sub-process of the first production process on the basis of a result of the quality determination of the cell culture product made in a required sub-process in the first production process while the first production process is being carried out;
• and
• the main control device is further configured to update the production schedule by updating a second production process different from the first production process on the basis of an update of the first production process, the update of the first production process being performed by adding a new sub-process to the first production process or by deleting an existing sub-process of the first production process, and
• further, on the basis of the update of the first production process, the update being performed on the basis of the result of the quality determination of the cell culture product made in the required sub-process while the first production process is being carried out, the main control device is configured to update the production schedule by exchanging the production process in a first production facility in which the first production process has been updated and the production process in a second production facility with each other.
