Substrate treatment apparatus and transfer schedule creation method

A method of creating a transfer schedule of a transfer object in a substrate treatment apparatus for treating a substrate,

• the substrate treatment apparatus, comprising:
• a plurality of treatment parts each configured to perform a predetermined treatment;
• and
• a transfer mechanism configured to transfer a transfer object, a plurality of transfer objects being transferred in a predetermined transfer-in order into the substrate treatment apparatus,
• the method comprising:
• acquiring a process job for transferring the transfer object by the transfer mechanism to at least one of the treatment parts and performing the treatment on the transfer object;
• and
• determining before starting transfer of one transfer object to the treatment part, when the process job is different between the one transfer object and a preceding transfer object transferred into the substrate treatment apparatus prior to the one transfer object and a same kind of treatment is included in the respective process jobs thereof, a possibility of performing preceding execution of executing the same kind of treatment on the one transfer object previous to completion of the same kind of treatment on the preceding transfer object.
