An ontological model of a product digital passport for the instrument-making industry

The paper formulates design alternatives for a product digital passport components in the instrument-making industry based on the results of the analysis of the information interaction between enterprises at various stages of an electronic product life cycle. An ontological model of the knowledge database of an electronic product digital passport for the instrument-making industry has been developed based on the metamodels standard elements – objects, relations and functions. The development process involved forming the lists of design and production procedures in accordance with electronic product life cycle stages, as well as attributes and data classes of the subject area. The paper describes the properties and attributes of classes (subclasses) and restrictions on their values and data types, determines information objects of the ontological model, which includes all possible options for describing components generalized for the instrument-making industry. The classification of the subject area terms is represented by hierarchical relationships according to the principle of inheritance of the object-oriented approach. Model classes are defined by sets of subject area terms using the Protégé system. The developed ontological model contains the complete data structure of the product being developed at the enterprise with the corresponding procedures for the instrument-making industry. The list of generated descriptions of the digital passport components at a particular enterprise determines the possible options for the content of design solutions. As a utilization example, there is a demonstrating algorithm for introducing the proposed ontological model to an enterprise in the instrument-making industry, which implements an electronic product digital passport to manage the internal processes of organizing production with the utilization of all stages of an electronic product life cycle. The resulting structure can be transferred to any other enterprise and industry, as part of the implementation of information structures of interaction when performing design work.
