In modern industrial production, enterprises face the dual challenge of ensuring supply chain quality reliability while controlling costs. Traditional single-link quality detection methods are inadequate for multi-link collaborative decision-making in supply chains. This study proposes a quality inspection method combining binomial distribution and Monte Carlo simulation for enterprise production processes. Integrating hypothesis testing based on normal distribution determines whether spare part defective rates exceed supplier-declared standards, guiding batch acceptance decisions. The model introduces a random allowable error E to adjust significance levels dynamically and errors, enhancing performance analysis. The study also considers inspection, dismantling costs, and substandard product exchange losses. Using Monte Carlo simulation, a revenue model is constructed for supply chain decision-making, providing accurate success rate solutions for parts, semi-finished, and finished products, aiming to maximize enterprise profit. Results show that precise quality control and cost management significantly improve economic efficiency and market competitiveness. For instance, selling a single product yields maximum profits increased from 9.60 yuan to 19.36 yuan (102% increase), with the second-best option reaching 15.19 yuan, a gap of 4.17 yuan compared to the optimal solution. This study offers robust theoretical guidance for quality control in enterprise production processes.
