Contribution to ECDIS Reliability using Markov Model

Integrated Bridge System (IBS) contains fully duplicated Electronic Chart Display and Information System (ECDIS). Although duplication should lead to higher reliability system, it is shown that reliability and availability it is not duplicated. Proper ECDIS maintenance includes updating both: information system itself and provided chart system. This procedure, in praxis, leads to less reliability and availability. Markov simulation model of ECDIS is given. New design concept is presented and proposed. ECDIS overall system is improved by adding cold standby system as precaution of errors due to updating and upgrading of system device.
