Selecting the right single-plant facility is crucial to maximizing the use of limited resources and minimizing effort waste. This study aims to provide decision-makers with a practical and effective approach that is as far as possible from individual subjective judgments when deciding on a single-plant facility. It differs from some other studies in the literature that leave the prioritization and weighting of criteria in the background in that it proposes a model in which decision-makers can determine their criteria for the location selection of a single facility and determine the extent to which these criteria are present in their alternatives. The step-wise weight assessment ratio analysis (SWARA) and the weighted aggregated sum product assessment (WASPAS) methods were used with an integrated approach. The results revealed that the approach used in this study was highly successful in the selection of a community pharmacy facility as a single-plant organization.
