This article focuses on the process of developing intelligent subsystem for reliability forecasting of discrete devices «FORECAST». Created system enables according to the physical characteristics to perform analysis of discrete device to predict the reliability of its work in time.
Reliability forecasting of the discrete devices taking into account interphase layer will allow without financial and time costs accurately answer the question about depending a reliability of discrete unit on area interphase layer formed by the interaction of two basic materials of discrete device element.
The disadvantage of created system can be considered a necessity of its setting for separate type of discrete device. Later, this disadvantage will be eliminated by creating libraries of parameters.
Software implementation of intelligent subsystem for reliability forecasting of discrete devices allowed to implement a method of forecasting technical condition of discrete device on the basis of proposed model by taking into account the physical properties of composite materials. Set of the reliability function values is obtained during the test of discrete device elements.
Verification of the results of intelligent subsystem for reliability forecasting «FORECAST» based on the physical condition of discrete devices is conducted to assess the working capacity of electronic control unit of the car system.
Accuracy of the results of the reliability values using the method of reliability forecasting of discrete devices based on modeling the degradation process of computer components is 7 %.
The workers of technical section spent 5 % more time to diagnostics by hardware maintenance compared with the time of application of intelligent subsystem for reliability forecasting «FORECAST».
