A model for building a digital network-centric system of data management to provide cost estimation of designed objects in the sphere of civil shipbuilding

Subject. The article addresses the prospective development of the civil shipbuilding sector in Russia. It considers digitalization of design, construction and production as a key driver of increasing the labor productivity at enterprises and organizations of the industry. Objectives. The aim is to present a conceptual model of a digital network-centric data management system for calculating the cost of works (services) performed (provided) by design organizations in the national civil shipbuilding, as a promising tool to improve the efficiency of cost estimation in the industry. Methods. We employ generally accepted methods of scientific knowledge, like analysis, synthesis, formalization and concretization, composition and decomposition, verification and expert evaluation. Results. We formulated and described a model of digital network-centric data management system. It consists of two elements, i.e. a centralized server management system for a cluster database and a client complex. The latter contains a personal calculation module, which is customizable for the needs of the organization, and a local (personal) database. Conclusions. If implemented, the presented conceptual model will enable a new level quality, speed, and accuracy of cost estimates of designed objects, as well as more effective accumulation and processing of relevant data for management decisions.
