Abstract:	Coal serves as a critical energy source for power generation and industrial operations, the demand for coal is rising, yet production levels are declining. In statistical quality control a statistical procedure can play a crucial role in boosting production efficiency and output. Techniques such as proximate and ultimate analysis, calorific value assessments, and ash fusion testing are employed to evaluate coal's composition and performance. Effective quality control techniques not only maximizes energy output but also reduces environmental impact and operational complications. This article introduces a stochastic approach to designing acceptance sampling techniques, aimed at enhancing the optimization of the Markov method for classifying conforming and non-conforming items. A Bayesian single sampling plan includes a defined sample size, an acceptance number, and a decision rule based on lower and upper thresholds, ensuring compliance with both buyer and vendor specifications for lot acceptance. The design methodology is developed using a Markov model to create a single sampling plan under Gamma-Poisson conditions. The sampling plan's performance is evaluated using Acceptable Quality Level (AQL) and Limiting Quality Level (LQL), optimizing thresholds through the minimum angle method. The practical applicability of this sampling plan is demonstrated through numerical examples within a coal manufacturing environment. [ABSTRACT FROM AUTHOR]
