ELEMENTS OF THE INTROSPECTIVE ANALYSIS TO EVALUATE SOFTWARE IN NAVIGATION

摘要

Maritime navigational systems are rather complicated and regarded as multifunctional ones. They include the following components: human, mechanical, technological, etc. Risks associated with these systems are complex and versatile. In order to reduce accidents at sea, it is required to systematize the causes of troubles. The research demonstrates that the events are not usually caused by a single breakdown or an error; they are usually represented as an interrelation of components affected by external factors (such as weather conditions). Only comprehensive synergy of software and components (modules) makes it possible to make correct decisions in various situations. The paper provides the introspective analysis of the software: Port to Port Pro, Skymate Pro 2012, WayPoint v3.1, and Admiralty Total Tide. A set of key factors that reflect the basic effect of factors on the system is formed. Parameters are analyzed with the use of real-world examples that are of practical value when these factors are taken into account.
