Value stream maps development based on the ontological approach

The purpose of the work is to evaluate and improve the efficiency of a manufacturing enterprise through the development and implementation of a value stream map. The analysis of the value stream map method was carried out, its shortcomings and features were identified. A map of the value creation flow of the current state of the production process was built and it was concluded that the map allows improving this flow process. Based on the analysis of a particular case of the Petri net, the need to determine objects, relationships and incidence relations is shown. The main objects are determined by building a frame model of the interaction of key production parameters. Relationships between objects and incidence relationships are revealed by building an ontological model. An analysis of the value stream maps development revealed five types of time costs. To reduce the travel time, loading and unloading time and eliminate downtime, it is proposed to use Petri nets using cyclograms.
