MAN-MACHINE SYSTEM FOR CONTROL OF SHIP BEHAVIOUR IN EMERGENCY CONDITIONS

摘要

The present paper deals with the marine problem of real-time decision making in various conditions especially when implementing the control of complicated movable objects (ships, underwater robots, etc.). The experience of human-operator helps to do it, but in this case it is rather difficult for him to predict behaviour of the damaged object, especially motion parameters, manoeuvring parameters and so on. Wherein, the risk of global breakdown of whole object is much higher. Presently, due to various factors like arising of ship's tonnage and speed or shortage of crew cause the increasing of emergency situation feasibility. The man-machine systems (MMS) can solve these problems. They are to provide human-operator (in interactive mode) with ability of playing with various emergency situations. Presently, there are many samples of ship MMS, which are able to make decisions in extreme conditions in interactive behaviour, but it can be done only if all ship systems operate in working order. But ship is an object with various separated channels and it must be considered as multicoupling system regarding to mutual influence of each channel. That is why the main idea of MMS improving is based on interactive SSM capability to make analysis of behaviour and manoeuvring parameters of ship in emergency conditions regarding to all valid damages in separate channels, which are recognised by means of the running structural-parametrical identification. The aim of research is to develop man-machine systems, which are able to help to human-operator with optimal decision making for solving tasks faced to complicated object and at the same time to ensure the safety of ships operation in extreme conditions.
