The present invention relates to a production management method for predicting time remaining until products are to be produced by way of a plurality of processing processes. Even when manufacturing apparatus are in an unstably operative state or the distribution of objects currently being processed in a plurality of processing processes is nonuniform, a remaining time can be determined accurately. On the basis of data stored in a process flow storage section, all remaining processes through which a predetermined lot is to pass before being produced as products are specified. On the basis of the data stored in an apparatus data storage section, a period of time required for processing in-process objects is determined for each of the remaining processes. All the required periods of time are summed, thereby predicting time remaining until the predetermined lot is produced as products.
