Abstract
Authors have been developing information system to support ship inspection. In the previous reports, ship inspection is classified into three stages (Plan, Do and Check), and information system for generating inspection information and damage information was developed. In this paper, integrated information system to examine the safety of ships is discussed.
In order to realize this, some new models and functions are proposed. Most important model is “Unconfirmed damage model”. This model is defined to express damages which are not found by the inspection. The characteristic of this model is to express damage without using specific information such as position or geometry. In addition, function to forecast the growth of damages and function to assume the unfinding damages are defined to generate “Unconfirmed damage model”.
Based on these considerations, prototype system was developed. In the system, appropriate inspection can be examined with considering uncertainness of the inspection, growth of damages and the importance of structures. Some examples are shown at the end of this paper.
