Estimation of labour intensity of diagnostic operations based on the method of functional checks
The article details the use of the method of functional checks for estimation of labour intensity of diagnostic operations in the process of service maintenance of ship control systems. Formation of subsequent paths is demonstrated on the basis of analysis of functional tasks of a system. Functional path of a present day information and control system is considered and its sequential chart is presented. Calculation of formal search pattern is performed and quantity of functional checks for finding of faulty module is specified. Labour intensity of fault searching is determined and the method for measurement of diagnostic procedures is proposed.
