Work Analysis of Maritime Passenger Terminals for Particular Region Based on Circos Plot

摘要

In terms of a systematic approach, till now it was not possible to investigate separately sea passenger terminals and the operation of ferry or cruise lines. So it is necessary to investigate their mutual influence, analyze the intensities, take into account the influence of the external environment and solve forecasting problems. This circumstance justifies the need to use new tools and models that allow analyzing the macro-level, consisting of all the ports in the region and the available ferry lines. For solving short-term forecasting problems, the class of polynomial problems has recommended itself well. But, when taking into account the mutual influence of the terminals and ferry lines on each other, the task becomes much more complicated. The discrete nature of the initial data, schedules of ship calls which need to be combined into a single array of data, comes to the fore in the study of processes. The process of functioning of an individual terminal with varying degrees of accuracy can be represented as a sequence of several typical design modes, each of which corresponds to a change in a certain set of characteristics and number of ship calls. But when solving problems at the macro-level, the article proposes to use optimization based on the circos plot. The construction of this type of diagram is associated with the fulfillment of certain boundary conditions, which makes it possible to define the boundaries of the region, to study and to form the completeness of the initial data. The object of the study is the interconnection of selected marine passenger terminals and the existing ferry lines. Based on the initial data, transformations were carried out and a circular (circos) plot of relations was constructed. Such diagram takes into account the analysis of the mutual influence of the terminals of one region. The obtained results make it possible to improve the quality of decision making, since a representation of the macro-level planning system of the ?marine passenger terminals - ferry lines? is formed within the framework of the selected marine region.
