Modeling Mechanical Component Failures during the Two-Dimensional Base Warranty Period for a Locally Produced Car in Iran

The sale of a product does not mark the end of the manufacturer's involvement, and providing services such as free repair of authorized product failures during the base warranty period is among the responsibilities and commitments of the manufacturer towards the customer. Fulfilling such commitments requires time and resources to identify and rectify failures. In such conditions, estimating the product failure process and associated costs can assist the manufacturer in providing the necessary provisions and resources for servicing and rectifying product failures during the base warranty period. In this article, data on failures of mechanical components of a locally produced car in Iran are collected during the two-dimensional base warranty period, and the probability distribution governing these failures is extracted. Subsequently, based on the mathematical model governing these failures, the expected number of failures is identified, and considering the cost of failures, the expected cost of repairing mechanical component failures is estimated. Finally, by interpreting these results, recommendations are provided for better estimating the failure process and associated costs.
