..., particularly for larger instances. A sensitivity analysis aimed at identifying more effective parameters reveals that the number of plants and products with only small fluctuations have the most and least impact, respectively, on the complexity of the MMMPRP model. Originality/value This model and solution...

... to March 2024. Subsequently, a fixed-effects model was used to determine the relationships between selected determinants and WCME. Moreover, the multi-layer perceptron method was applied to calculate the artificial neural network (ANN). Finally, sensitivity analysis was conducted to determine the relative...

... are identified based on the literature review and case study. Then, a model is proposed for supplier selection using AHP approach followed by a detailed sensitivity analysis. Practical implications – This paper contributes to supplier selection process, and points out the importance of supplier selection...
