<p>Failures in technical systems lead to damage to equipment and economic <br /> losses. Reliability is one of the main concerns in all automated control systems. <br /> Studying the impact of technological factors on product reliability and eliminating <br /> them is a critical task. When designing any new device, evaluating its reliability is <br /> a crucial indicator in determining whether the associated costs are justified. This <br /> article focuses on solving a practical issue by evaluating the reliability of a solar-<br /> powered device for the primary processing of silkworm cocoons. The device plays <br /> an important role in the sericulture industry, and its reliability directly affects <br /> economic efficiency. The study uses exponential distribution laws and mathematical <br /> modeling methods to assess reliability. Various coefficients were considered in <br /> calculating the failure intensity of the device’s components, bringing the results <br /> closer to real-life conditions. Factors such as thermal and electrical loads were <br /> identified as primary indicators affecting device reliability. The research results led <br /> to specific recommendations for improving device design, including the use of high-<br /> quality thermal insulation materials, enhancing the durability of solar panels, and <br /> implementing automatic temperature and humidity control systems.</p>
