Abstract:

The concept of quality has been defined from different perspectives in the literature. One of the most common and accepted definitions is Juran's approach, which refers to quality as "the suitability of a product or service for customer use". Quality costs, on the other hand, include the costs arising from the existing poor quality and the costs incurred to prevent poor quality and reach the desired quality level. In the literature, quality costs are generally classified as prevention costs, evaluation costs, and error costs. The concept of Exergy, on the other hand, provides information about the general efficiency of the system by measuring the thermodynamic performance of production systems and reveals how much of the energy entering the system is converted into practical work. It quantitatively determines the losses in energy and resource quality by revealing the points where irreversibility in the production system is concentrated. Exergoeconomic analysis involves calculating the monetary equivalent of these losses. This study aims to discuss whether exergy-based inefficiencies can be handled from the perspective of quality costs. Thus, prevention, evaluation, and error costs; Exergy is associated with destruction and loss, creating a holistic decision support structure for continuous improvement and cost reduction.
