semi-prepared food

Uncertainty in food supply in the country has heightened the focus on the supply chain of semi-prepared foods. Like many economic sectors, the food supply chain has not been immune to the impacts of the COVID-19 pandemic. Food supply, influenced by the behaviors of governments and customers during such crises, can exacerbate uncertainties in the supply chain, underlining the need for simulating the behavior of supply chain actors. Accordingly, the aim of this study is to develop an agent-based simulation to analyze the relationships between actors in the supply chain of ready and semi-prepared foods concerning raw material imports and final product exports during the COVID-19 pandemic.

This study is applied in its aim and descriptive-analytical in terms of data collection, utilizing agent-based simulation techniques. The case study for simulating pandemic conditions in the supply chain is one of the ready and semi-prepared food companies in Tehran Province with a production capacity of 216,000 tons per month. To identify factors, variables, and parameters for the agent-based model, the research employed thematic analysis, reviewing prior studies, and conducting interviews with 20 industry experts from the ready and semi-prepared food sector and supply chain experts from Amadeh-Laziz Company.

The findings identified three main actors in the food supply chain that play a role in exports: “Government”  (e.g., customs, national standards organization, consumer protection organizations, industry and mining banks, Iran Chamber of Commerce-Industries-Mines and Agriculture, and the Food and Drug Administration), “Supply Chain Companies” (e.g., domestic suppliers, foreign suppliers, manufacturers, and distributors), and “Final Customers” (e.g., domestic and foreign customers). The key uncertainty identified in interviews was governmental intervention or non-intervention in exports and imports.Accordingly, two scenarios were developed: “Governmental intervention in exports and imports”, and “Lack of governmental support in exports and imports during the pandemic”. These scenarios were analyzed using agent-based simulation to examine the relationships, characteristics, and decision-making behaviors of supply chain actors. Additionally, fuzzy DEMATEL was used as a complementary method to identify the most significant relationships among actors in the ready and semi-prepared food supply chain. Simulation parameters included: Import tariffs on raw materials (%), Export tariffs on final products (%), Total monthly domestic demand (in thousand tons), Total monthly foreign demand (in thousand tons), Total monthly demand (in thousand tons), Maximum production capacity (in thousand tons).Simulation variables included: Percentage change in total costs compared to the base price, Percentage of completed domestic customer orders, Percentage of completed foreign customer orders, Total completed orders (total sales volume), Profits from the domestic market, Profits from the foreign market, Percentage of overall profitability. The simulation was performed under the two scenarios of governmental non-intervention and governmental intervention in importing raw materials and exporting final products, with emphasis on two main variables: profitability and order fulfillment rate, which encapsulate the model’s overall outcomes.

The results indicate that under the governmental intervention scenario, profitability increased by 6%, and total order fulfillment improved by 14%. Based on the defined criteria for scenario comparison, the second scenario (governmental support) provides more favorable conditions for supporting domestic production, enhancing employment levels, and ensuring food security in both domestic and international markets.
