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

An information processing method for execution by an information processing apparatus that supports work by a user who uses drawings for a plant, the information processing method comprising:

• judging whether a first drawing and a second drawing including elements configuring the plant have different formats;
• generating an intermediate model, when the first drawing and the second drawing are judged to have different formats, for at least one of the first drawing and the second drawing such that a format of the first drawing and a format of the second drawing are matched;
• judging whether a difference exists between the first drawing and the second drawing based on the generated intermediate model,
• generating the intermediate model, when the elements to be depicted in the first drawing as determined based on a first format include an element unnecessary in the second drawing as determined based on a second format, for the first drawing by removing the element unnecessary in the second drawing from the first drawing;
• converting each of the first drawing and the second drawing into an abstract model represented by element information indicating the elements and connection information indicating a connection relationship between the elements;
• generating one abstract model based on the first drawing as the intermediate model with information level matching applied thereto;
• and
• generating display information, when it is judged that a difference exists between the intermediate model and another abstract model based on the second drawing, for displaying a differing portion in a different form than another portion.

A non-transitory computer readable medium storing a program executable by one or more processors to cause an information processing apparatus, which supports work by a user who uses drawings for a plant, to execute functions comprising:

• judging whether a first drawing and a second drawing including elements configuring the plant have different formats;
• generating an intermediate model, when the first drawing and the second drawing are judged to have different formats, for at least one of the first drawing and the second drawing such that a format of the first drawing and a format of the second drawing are matched;
• judging whether a difference exists between the first drawing and the second drawing based on the generated intermediate model,
• generating the intermediate model, when the elements to be depicted in the first drawing as determined based on a first format include an element unnecessary in the second drawing as determined based on a second format, for the first drawing by removing the element unnecessary in the second drawing from the first drawing;
• converting each of the first drawing and the second drawing into an abstract model represented by element information indicating the elements and connection information indicating a connection relationship between the elements;
• generating one abstract model based on the first drawing as the intermediate model with information level matching applied thereto;
• and
• generating display information, when it is judged that a difference exists between the intermediate model and another abstract model based on the second drawing, for displaying a differing portion in a different form than another portion.
