The article presents the creation of a software platform for automatic configuration of ground facilities systems using ontological models, intelligent algorithms for selecting objects and generating options. The mathematical formulation of the configuration problem, the architecture of the application and the user interface for entering design data and obtaining the result of selecting objects with a high degree of detail are given. In the future, the developed prototype can become a tool to support the work of system engineers and technologists at the stage of conceptual design during the variable study of the configuration of the oil and gas system, taking into account the requirements.

The possibility of using neural networks to classify the states of complex objects is considered. A software implementation of a neural network classifier is made and the results are compared with a selection algorithm based on K-nearest neighbors.

The paper considers the implementation of the Case Base Reasoning method when managing a city infrastructure complex technological object. A method of formalizing the situation at a complex technological object using a matrix of states is presented. A method is proposed for determining the proximity of situations in the state space, taking into account the proximity of the states of each element of a complex technological object. The implementation of the proposed method when selecting a situation from the knowledge base allows avoiding collisions when two critically different situations with different solutions are selected.
