Abstract: Risk element information indicating risk elements is acquired. An asset capable of becoming a fault due to a risk element indicated in the risk element information, and a fault probability that the asset becomes the fault are specified based on static configuration information. A risk model in which the asset capable of becoming the fault and the fault probability are associated is generated in advance. In response to a designated input, an one asset to be evaluated is specified as an evaluation target asset, based on the designated input. A risk model related to the evaluation target asset is specified. A risk evaluation value being an index indicating a risk of the evaluation target asset is calculated based on the fault probability of the evaluation target asset and the static configuration information. The risk evaluation value of the evaluation target asset is associated with the asset of the risk model.

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.

Abstract: A solution is calculated using a tree search within a limited calculation time. A solution searching device that performs solution search using a search tree includes a search tree expanding unit that creates a node based on options until a stop condition is satisfied, an evaluation calculation unit that calculates an evaluation value for an leaf node using a first evaluation method, and a search solution determination unit that sequentially updates an evaluation value of an upper node based on an evaluation value of a lower node to determine a search solution.
