Abstract: A production system between processes is automatically determined using work performance data acquired at a production site, and a process model in which a flow shop and a job shop are mixed is automatically generated. A process model automatic generation system 210 reads work performance data from work performance data 120 and extracts a process flow for each product (130). Next, a synthesis flow obtained by combining a plurality of process flows is created, and a production system between processes corresponding to a closed path is changed to a job shop to automatically determine a production system (140). Finally, a process model in which a flow shop and a job shop are mixed is generated (150) and displayed on a display screen 160.

Abstract: To provide a technique for supporting generation of a process model suitable for a task generated on a site. A process model creation system creates a model used for managing, in a process including a plurality of tasks, site data acquired on a site of each task, and defining a flow of the tasks in the process. The process model creation system includes: a model accumulation unit configured to accumulate the model; a difference data creation unit configured to create, based on the site data acquired on the site, an instance indicating a flow of actually executed tasks, and extract differences between the instance and the model as difference data; and a model modification unit configured to create a modification proposal of the model based on the difference data.
