The aim of the present study is to develop a data-driven and predictive model for forecasting the product acceptance rate in a lean manufacturing environment using an artificial neural network. In the first step, potential variables influencing product acceptance were identified through a systematic review of the literature and by eliciting the opinions of experts in lean manufacturing and quality management. The final selection of input variables was then carried out using the fuzzy Delphi method. Subsequently, 4,800 data records extracted from food industry production lines over a two-year period were used as the quantitative data for the study. The predictive model was designed and trained based on a feedforward artificial neural network, and its performance was compared with several benchmark regression models, including linear regression, decision tree, random forest, and support vector machine. The results showed that the artificial neural network model, with a coefficient of determination of 0.88, achieved higher predictive accuracy than the benchmark models and demonstrated a strong capability in modeling nonlinear relationships between quality- and process-related variables and the product acceptance rate. Furthermore, variable importance analysis revealed that raw material quality and the percentage of production waste played the most significant roles in predicting the product acceptance rate. The findings indicate that improving a single factor in isolation does not guarantee an increase in product acceptance, and that sustainable outcomes can only be achieved through the simultaneous management of multiple key variables.
