Abstract
Introduction. The majority of radioelectronic systems are hardware-software systems. Their reliability is defined as the reliability of hardware and software. Methods for estimating software allow to predict reliability based on experiments and tests during the testing verification and validation time, but there is no specific models for assessing the reliability during operation time. Problem statement. In many approaches, when assessing the reliability of hardware-software systems consider that software reliability is equal to 1, and consider only reliability of hardware. In other approaches consider that the reliability of PAS depends on the software and hardware reliability. Hardware and software features differ significantly. Important is to create methodology for determining the reliability of hardware-software systems considering hardware and software adequate models. Developing software reliability models. Was carried out the analysis of software reliability models according to its life cycle. Software reliability model in operation time is proposed as a set of Heaviside functions. Developing hardware reliability models. Was carried out the analysis of hardware reliability according to the technology [3]. Developing software-hardware reliability models. Was carried out the analysis of software-hardware systems considering the reliability of hardware and software during operation time.
