Identification, Ranking, an‎d eva‎luation of Supply Chain Strategies Using a Hybrid DEMATEL–PROMETHEE–Simulation Approach (Case Study: Rice Supply Chain in Gilan Province)

The rice supply chain in Gilan Province faces multiple challenges, including rising production an‎d distribution costs, severe price fluctuations, an‎d a decline in final product quality—issues that have significantly affected the efficiency an‎d sustainability of the chain. In response to these challenges, the present study proposes a comprehensive an‎d integrated framework aimed at identifying, weighting, ranking, an‎d eva‎luating the effectiveness of improvement strategies to support scientific decision-making an‎d effective policymaking. In the first stage, a set of key strategies was extracted through a systematic review of the literature an‎d consultation with local experts. The DEMATEL method was then applied to analyze the degree of influence among decision-making criteria. Subsequently, the PROMETHEE method was employed to rank an‎d prioritize the identified strategies. In the next step, system dynamics models were developed in the Vensim environment an‎d calibrated with real data from 2018 to 2023 to validate their structural accuracy. Based on these models, various policy scenarios for the period 2024–2041 were simulated to examine the effects of technological solutions—such as the use of improved seed varieties, mechanized harvesting, an‎d modern drying an‎d sorting systems—on the overall performance of the supply chain. The integration of these methods provides an analytical framework that enables multidimensional analysis an‎d sensitivity testing across different scenarios, ultimately allowing decision-makers to make more accurate an‎d effective choices tailored to the real economic, technical, an‎d climatic conditions of the province
