Abstract: Proposed are a process model creation system, a process model creation method and a process model creation program capable of reducing the man-hours required for generating a process model without having to prepare a process model for each of the plurality of business systems. The present invention comprises a data structure conversion unit which converts each data of each business system into a data structure of a common BOP (Bill of Process), a model generation unit which creates a plurality of adapter models from the data structure of the common BOP, and a process model synthesis unit which extracts differences between the plurality of adapter models and creates a synthesis process model.

Abstract: A process model management system includes a processor and a storage device, the storage device being configured to store actual data of tasks at a manufacturing site and master data including design information of the tasks. The processor is configured to generate an actual process model based on the actual data, generate a master process model based on the master data, generate a synthetic process model by synthesizing the actual process model and the master process model, when the actual data is changed, detect a difference of the actual process model due to the change of the actual data, when the master data is changed, detect a difference of the master process model due to the change of the master data, detect a difference of the synthetic process model due to the change of the actual data or the master data, and output a notification based on the detected difference.

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.
