Reliability and Communikation in Man-Machine-Systems
Kovář, Tomáš ; Žurek, Martin (referee) ; Havlíková, Marie (advisor)
The objective of this work is to analyse the technical and human reliability in the man-vehicle system. The reliability of the whole system is given by the individual reliabilities of technical subsystems and human operators. In the analysis of safety and readiness of technical systems, it is necessary to monitor human effects on the reliability, safety and readiness of these systems, which directly put people’s lives at risk. The human operator influences the safety and reliability of the whole system by his actions and operation of the device. The quantitative evaluation of human reliability is based on an overall probabilistic safety analysis. Since drivers directly control the means of transport, the human operator’s reliability is entirely determining for the overall reliability of the system. External and human factors influencing performance affect the man-machine system. The activity tree model serves for the evaluation of reliability of the MMS system and provides a concise, organised and well-arranged description of defects within the system.

Diagnostic of Systems with a Human Operator
Havlíková, Marie ; Malec, Zdeněk (advisor)
The doctoral thesis is thematically focused to human operator systems significantly contributing to this system reliability and safety. The theoretical part of the thesis is concerned with human activities and communications in MMS system, valuation and estimation of human reliability probability in MSS. The important part of the thesis is also a description of human operator neuromuscular system as an executive powerful system on MMS system regulating activities and the summary of human driver models in compensative lateral car control. The practical part of the doctoral thesis is based on analyses created by experimental data of drives. Experimental drives were done on drivers set following different backgrounds and different sleep deprivation at whole day. All experimental data was realized from the cooperation and following the agreement of Faculty of Transportation Science research centre on Prague ČVUT. Another part of thesis includes driver simulation model proposals with nonlinear components for lateral car control. Simulation model drives are compared with real drives or drivers on drive-simulator and there are monitored identical and different dynamic movement characteristics. The main target of doctoral thesis is to detect and obtain significant dynamical drive experience characteristics based on experimental data analyses. As well to found drive characters variability owing to driver’s fatigue and determinated evaluated characteristics changes. Acquired results of thesis should help in assistant systems that in cooperation with other components alert to micro-sleep and run off drive possibility.

Assessment of the operator reliability of the selected machine
Jakl, Tomáš ; Rozehnalová, Jana (referee) ; Kotek, Luboš (advisor)
The master thesis is focused on the reliability of the human factor in the operation of the production machine. In the first part the basic legislative requirements for safety and reliability of work are presented. In the second part, the reliability of the human factor is discussed along with a description of selected methods for assessing the reliability of the human factor. The research section then concludes with a proposed methodology for human factors assessment for the manufacturing process. In the practical part, the proposed methodology is applied to the selected process, which includes risk identification and outputs from the selected methods. The thesis then concludes by recommending preventive measures to eliminate the identified risks.

Mam-Machina-Systems and their Reliability
Jurčík, Petr ; Skřehot, Petr (referee) ; Havlíková, Marie (advisor)
The point of this work is to describe and analyse human and technical reliability inside a man-vehicle system. The reliability of whole system is given by partial reliabilities of technical sub-systems and reliability of a man like a human operator. Human operator influences security and reliability of whole system by his activity and servicing of equipment. It is necessary to monitor and evaluate this activity in the analysis of security of technical systems. By the evaluation of human reliability people come out of the whole probability analysis of security. Inside the man-vehicle system the vehicle is operated by the driver and therefore influence of human operator is totally fundamental for the total reliability of this system. Graphic fault tree model shows different combinations of equipment failures and people failures which can lead to the accident.
