摘要： A plant simulation device includes a first storage that stores a model that models a state of a facility in a plant, a first parameter that is fixed at a start operation of the plant, and a second parameter that is varied during an operation of the plant, the first parameter and the second parameter being set in the model, and a simulator that compares a process value of the facility with a simulated value calculated using the model and that adjusts the first parameter and the second parameter.

摘要： A plant state displaying apparatus displaying information representing a state of a plant includes a generator that: acquires plant information from at least one of devices, apparatuses, and facilities installed in the plant; calculates a state value representing the state of the plant using the plant information; and generates a plant state diagram in which at least one of a color and a density of at least one of devices, apparatuses, and facilities from which the plant information is acquired is changed according to magnitude of the state value; and a display that displays the plant state diagram generated by the generator as the information representing the state of the plant.

摘要： An evaluation apparatus includes a storage unit that stores a model modeling a state of a facility provided in a plant, a simulator that adjusts a parameter that is set in the model so that a difference between an actual measurement value based on a process value of the facility in a first state and a first simulate value calculated by using the model is equal to or less than a threshold, and an estimation unit that estimates a first estimated operating point that indicates an operation state of the facility in the first state based on the adjusted parameter.

摘要： 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.

摘要： An information processing apparatus (10) is for supporting work by a user who uses drawings for a plant. The information processing apparatus (10) includes a controller (15). The controller (15) 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 (15) 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.

摘要： 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.

摘要： 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.
