Radiocommunication Events Management System
Opis:: The presented simulation model of radiocommunication events management allows to investigate problems occurring in marine radiocommunications. Based on a variety of research methods, we focus on the method of computer-based simulation, and describe the stages of construction and structure of the simulation model. Finally, we discuss possible applications of the developed model.

allocation model
Opis:: This article presents the structure of a model of the allocation of radiocommunication events at coastal radio stations, land-based satellite stations and on vessels in sea area A3. The propagation of radio waves in the HF band has been analyzed to examine the range of various radio stations and their capabilities of establishing communication between each other. We also present methods of modeling and displaying the deployment of individual stations, of presenting radiocommunication events as a function of time using time diagrams, as well as the manner of the chronological presentation of radiocommunication events and related decisions. It has been shown that there is a relationship between the effectiveness of communication and propagation conditions that is strongly dependent on the time-of-day. We present the need to develop a decision support system for the radio operator on the bridge.

Opis:: The article proposes a model of the system supporting the decision-making process relating to the radio operator on board a ship after a distress alert is received by a Digital Selective Calling (DSC) controller working on VHF channel 70. The model is aimed at the implementation into the system of radiocommunication event management. The system takes into account the existing Radio Regulations. The model makes use of Petri nets, which are elements of graph theory. The time domain is comprised in the developed graph, and the states (places) and transitions capable of autonomous functioning are separated, as are those places and transitions requiring direct operator action based on empirical knowledge.

Opis:: This paper presents an analytical method for determining marine VHF communication bands based on the propagation model included in the International Telecommunication Union (ITU) recommendations. The developed method to determine communication bands was compared with the model recommended by the International Maritime Organization (IMO). The usefulness of the method developed by the authors has been demonstrated for the needs of the Radiocommunication Events Management System (REMS).
