Project summary

In conditions of autonomous flights which differ from usual earth ones it occurs reasonable to include subsystems of self-control and interpretation and psycho-somatic conditions of a spaceman-operator into the composition of information (expert) system.

This system will enter the software composition of computers for airborne systems of orbital manned stations as the system "partner-assistant-consultant" aiming the prevention of mentally (psycho-physiologically) uncomfortable conditions, increase of a workability and security degree in extreme conditions of their activities on the orbital manned space stations.

The Project envisages the construction of the initial version of "demonstration prototype" of the information (expert) system "ESSP" (Expert System Spaceman Partner) and after its perfection the construction of the final version of the "ESSP" system "research prototype" is intended.

"ESSP" with its possibilities can appear as one of the new systems of information technologies.

It is possible that "ESSP" system will participate in international conferences exhibitions and in seller's markets as a separate system for supporting pilots piloting in conditions of manned space ships.

The actuality of the problem is caused by the increase of the flight duration of orbital manned stations recently and the working time of a spaceman in open space increased abruptly. In this connection the updating and development of abilities of operators in autonomous conduction of work is a big problem. In contemporary conditions when the volume of necessary knowledge increases abruptly it is necessary that the pilot could independently supplement his knowledge, orient in the current of information and, which is especially significant, realise his inpidual knowledge and implement an active control. In conditions of unusually big information and emotional and mental overloads (deep feelings due to the responsibility for taking right decisions, unforeseen stressing conditions etc.) the nature and specific character of the operator-spaceman activity change essentially.

The practice and results of medical and space researches show earnestly that the success of the man's activity in extreme conditions is also determined by many subjective factors equally with objective ones. It is the sense of duty, will, emotional stability and health condition etc. The most important subjective factor is the level of professional training. The high level of knowledge, abilities and skills is a necessary condition for not only qualitative implementation of work but for keeping the emotional stability, prevention of panic and development of generalised defence and stressing reactions as well. Since the experimental conditions can form under the influence of factors of various nature and unfavourable action of factors can be not only with the increase but sometimes with the definite decrease of knowledge one must bear in mind the variety and complexity of acting mechanisms in extreme conditions on the state ant workability of the man-operator.

'The multi-factor character of the researched problem compels to use the modern system of the theory of indistinct multitudes, psychological theory of the cognitive dissonance, methods of neural cybernetics, artificial intellect etc.

These theories will give the opportunity to create the data knowledge base necessary during the construction of our proposed “ESSP” expert system.
