Hierarchy of input elements in a model of search areas and analysis of model sensitivity in order to determine the quality of information on environmental conditions increasing search and rescue operation at sea.

Process of planning and carrying out of the search and rescue operation is quite a complex matter.

SAR operations require quite a large quantity of calculations which are very often time consuming and have to be carried out when survivors at sea are expecting help, hence it is necessary to use appropriate tools facilitating the planning process of the SAR operation. Computer systems are used as such tools. The efficiency of the operation is decided by many factors, the most important of which is correct modelling of the search zone.
