Provided is an analysis apparatus, including a work cost calculation unit configured to calculate a change in a work cost of a target plant when at least some target work, among work of an operator required to operate the target plant, is automatized. The analysis apparatus may include an automation cost calculation unit configured to calculate an automation cost for automatizing the target work; and a cost comparison unit configured to compare the work cost to the automation cost.

Analysis apparatus, analysis method and computer readable medium

Provided is an analysis apparatus comprising: a variation model storage unit configured to store a plurality of variation models indicating variation in characteristics of a plant corresponding to an operating condition of the plant; a model extraction unit configured to acquire structure information indicating a structure model of an analysis target plant and to extract the variation model corresponding to the structure model; and an analysis unit configured to analyze the analysis target plant, based on the structure model of the analysis target plant and the variation model extracted by the model extraction unit.

Analysis apparatus, analysis method and computer-readable medium

An information processing apparatus () is for supporting work by a user who uses drawings for a plant. The information processing apparatus () includes a controller (). The controller () is configured to convert a drawing including elements configuring the plant into an abstract model represented by element information indicating the elements and connection information indicating a connection relationship between the elements. The controller () is configured to generate display information, when it is judged that a difference exists between one abstract model based on one drawing and another abstract model based on another drawing, for displaying the differing portion in a different form than another portion.

Information processing apparatus, information processing method, and non-transitory computer readable medium

A drawing management apparatus of the present disclosure includes a processor that generates a virtual plant based on various types of drawings of a plant, updates the virtual plant, when a change is made to a drawing among the various types of drawings, based on the change, and notifies a predetermined recipient, via a communication interface, of information related to a change made to the virtual plant by updating.

Drawing management apparatus, drawing management system, and drawing management method

An engineering support system that supports engineering of a process control system, includes: a storage; and a processor connected to the storage and that: transforms design drawings into semantic models and outputs the semantic models to the storage; and generates a combined semantic model by combining the semantic models based on a degree of similarity among the semantic models and outputs the combined semantic model to the storage, wherein each of the semantic models is expressed by first information indicating elements included in the design drawings and second information indicating a relationship between the elements.

Engineering support system and engineering support method

An information processing apparatus () is for supporting work by a user who uses drawings for a plant. The information processing apparatus () includes a controller (). The controller () is configured to generate an intermediate model, for at least one of a first drawing and a second drawing that include elements configuring the plant and are judged to have different formats, such that the format of the first drawing and the format of the second drawing are matched. The controller () is configured to judge whether a difference exists between the first drawing and the second drawing based on the generated intermediate model.

A drawing management apparatus is for managing various types of drawings of a plant and includes a processor and a communication interface. The processor is configured to notify, via the communication interface, a user or terminal apparatus handling a second type of drawing different from a first type of drawing of information related to a difference in the first type of drawing acquired based on a comparison between a new version and an old version of the first type of drawing.
