Rational Lifetime of a Vehicle in Terms of Ensuring Security of Its Design

摘要

In recent years, automakers have been actively developing and implementing electronic active safety systems. These components and systems increase the vehicle safety, but complicate the design and increase the cost of maintaining it in good condition. Numerous theoretical studies have noted that the nature of the technical readiness coefficient changes during the time of operation exponentially, and by operational kilometers - linearly. The performed research allows concluding that the value of the realized technical readiness coefficient is determined by its minimum permissible value. The performed situational analysis suggests that the solution of the problem to ensure the lifetime of a vehicle, for example, according to the standards of safety features, requires optimization of solutions. This requires the formation of the multicriteria quality scorecards of the vehicle performance properties.
