Abstract: A mode selection is carried out prior to the outward transfer of a substrate to be processed from an indexer block. When a “processing sequence priority mode” is selected, a transport path for the substrate is defined prior to the outward transfer of the substrate. The definition of the transport path is carried out by determining to which of a plurality of parallel processing parts for performing each parallel process the substrate is to be transported. Next, based on the defined transport path, an adjustment is made to a processing condition established for each substrate processing part included in the transport path. Thereafter, the unprocessed substrate is transferred outwardly from the indexer block, and is transported and processed along the defined transport path. On the other hand, when a “throughput priority mode” is selected, a substrate is transported to a vacant one of the plurality of parallel processing parts.
