THE CONCEPT OF AN INTEGRATED INFORMATION SYSTEM FOR PLANNING OF FLEET OPERATION IN THE ARCTIC

There are several reasons for the multiple increase in intensity of Arctic shipping in the near future. This makes quite relevant the development of tools and algorithms for information support of navigation in this complex region.In this article, we describe the concept of an integrated information system for planning the operation of cargo ships and icebreakers in the Arctic. The planning task is divided into three levels: operational, tactical and strategic. The goal of operational-tactical planning is to increase the efficiency of the maritime transport system, taking into account the requirements for ice navigation safety. This task includes both the optimization of vessel routes and the development of an optimal plan for their icebreaking support throughout the region. Such a plan includes geographic points and dates for the convoy formation and splitting up, as well as the convoy composition, recommended routes in ice, etc.

The structure of the Centralized system for tactical and operational planning of shipping in the Arctic includes four main domains. The “Ships” Domain includes the software infrastructure for the generation and storage of information models of vessels, icebreakers, as well as computational models of vessel movement in ice. The “Passages” Domain is used to store data on scheduled, current and completed passages of ships and icebreakers. The “Nature” Domain describes and displays the environmental parameters. It contains both the static information elements (navigation maps and databases of navigation conditions) and the components for operational monitoring and forecasting of weather and ice cover dynamics. The ship onboard recorders of voyage data and environmental parameters play a special role in the System, since they allow collecting big data to improve various computationalalgorithms. The services joined in the “Planning” Domain from the intellectual core of the System; they are related to the methods of automatic decision making andtheir implementation is possible with the use of modern technologies, such as knowledge bases and machine learning techniques.

The article highlights the main groups of scientific and methodological problems that challenges the implementationof the proposed System. They are: (1) spatial logistic planning of ships’ and icebreakers’ operation at the tactical and operational levels; (2) the need to improve the accuracy as well asthe horizon of operational ice forecasts; (3) the development of a robust computational model to predict the parameters of vessel and convoy movement in ice, taking into account all ice features that determine ship performance.Implementationof the System will improve the economic efficiency and safety of Arctic shipping by means of the centralized planning of ships and icebreakersoperation.
