The article presents the problem of the influence of thermodynamic factors on human fallibility in different zones of thermal discomfort. Describes the processes of energy in the human body. Been given a formal description of the energy balance of the human body thermoregulation. Pointed to human reactions to temperature changes of internal and external environment, including reactions associated with exercise. The methodology to estimate and determine the reliability of indicators of human basal acting in different zones of thermal discomfort. The significant effect of thermodynamic factors on the reliability and security of person.

The paper outlines the theory of risks occurring during the use of the antropotechnical type systems. In the presented approach a logical theory of mathematical principles of reliability and man - machine systems theories have been used. Unreliability and failure of the man - machine system depends on the circumstances in which it is located for which four states is possible to identify: natural environment, environment technosphere type state, man psychological state, device technical state. It was pointed out that into the phenomenological reality type surroundings where antropotechnical type systems is operating, potential damages and in their follows as inefficient damages and losses are possible, results processing both energy and information into the useful and awaiting results. It consists of a variety of factors forcing undesirable changes in the antropotechnical type system. The destruction process of the antropotechnical type system under operation results external forces treatment from the environment, including technosphere type of infrastructure and internal forces of destructive processes, as well as any control errors generated by the human (e.g.: device operator, decision maker). The possible sequence of cause undesirable consequences inevitably resulted in the creation is presented as follows: 1. primary causes type of adverse events - they are internal and/ or external factors and failure to enforce human from original reliability, 2. secondary causes type effect - they are damages and losses and the consequences of legal and financial nature. The primary causes type results with damage to the device, the inefficient operator ending destruction and degradation of environment. It has been accepting that risky procedure is based on taken responsibility for any damages or losses, taken danger possible events of any project under consideration, as well as any results which are not known in advance. The risky decision is when we are taken any decision under uncertainty conditions and possible hazards whose consequences to be feared. It was pointed out also that in certain circumstances, dynamic assessment of acceptable level of risk is based on estimation the ability the expected remaining time to hazardous events. It was suggested that the theory of risk in practice forms the scientific basis for engineering safety as a separate discipline of technical sciences.

W referacie przedstawiono wybrane, ważniejsze elementy cybernetycznej teorii zagrożeń. Przyjęto, że teoria zagrożeń, powinna się zajmować modelowaniem i formalnym opisem zachowania się układów antropotechnicznych, działających w niebezpiecznych okolicznościach. Jako podstawowe, opisywane są trójstanowe systemy: człowieka, obiektu technicznego i infrastruktury transportu. Jako oczywisty aspekt teorii uznano jakościowy i formalny opis bezpiecznościowych charakterystyk.

The paper presents selected highlights of the cybernetic theory of hazards. This theory is a basis for high school teaching of safety engineering. It is assumed that the theory of hazard, should be dealt with modeling and formal description of the behavior of the antropotechnical system in dangerous circumstances. As a basic tri-state systems are described: operator, mean and infrastructure of transport. The interactivity elements of system present matrices of desired and undesired incidents transition in the system multi-state threats. As an obvious aspect of the theory was qualitative and formal description unsafety characteristics. Unsafety states of antropotechnical system divided into border and critical. The critical state of the system that not less than one element of the system is in critical condition. Times attributed the occurrence of damage, making mistakes and critical impact forcing factors are treated as random variables. It is assumed that the basic characteristics of developments the dangerous circumstances are the intensity of critical failures and / or irreversible human errors. The unsafety characteristics represent a conditional unsafety probability and are associated with the coefficients of expected time to critical events.

W referacie przedstawiono problem wiarygodności diagnozowania stanu obiektów wchodzących w skład lotniczego systemu antropotechnicznego pod kątem funkcji celu. Skupiono się głównie na problemach występujących w naszym lotnictwie wojskowym. Wykazano, że diagnozowanie poszczególnych elementów systemu bez uwzględnienia ich wzajemnych relacji jest niepełne, a czasami dające mylny obraz rzeczywistego stanu systemu. Zaproponowano kompleksową relacyjną metodę diagnozownia systemu antropotechnicznego w układzie {układ oddechowy pilota - pokładowa instalacja tlenowa} oraz omówiono jej założenia i potencjalne korzyści zastosowania.

This paper describes credibility of the diagnosis' state of object included in the aviation anthropotechnical system with special focusing on the function of purpose. It revealed that the diagnosis of every single element in the system without paying attention to their bilateral relations is insufficient and it frequently pictures a vague and false vision of reality. It has been proposed a full interaction method of diagnosis of the anthropotechnical system in a relationship {pilot's respiratory system – board oxygen installation} and described its assumptions and its potential profits while used.
