To provide a production management system of a recycled aggregate by which a primary treatment field suitable for the primary treatment of the aggregate can appropriately be selected from a plurality of primary treatment fields, and the sales destination of the recycled aggregate manufactured by treatment in a secondary treatment field can appropriately be selected.

The production management system 1 manages the manufacturing of the recycled aggregate through processes including a primary treatment process for carrying out the primary treatment of raw materials including the aggregate and a secondary treatment process for carrying out the secondary treatment of raw materials processed by the first treatment process. The production management system 1 comprises an information treatment means 2, thereby selecting the primary treatment field Fq suitable for carrying out the primary treatment based on the primary treatment field location data related with the location of each primary treatment field Fq and raw material location data related with the location of the raw materials to be recycle-treated.
