Wheat is a key element of national food security, providing a major share of the calories and protein required by the population and therefore playing an important role in public health and livelihoods. Ensuring its consistent production and reliable access is essential for economic stability, food equity, and social resilience. In this regard, this study develops a multi-period, multi-product stochastic optimization model to design a resilient wheat supply chain under disruption risks. The supply chain includes suppliers of agricultural inputs (seeds, pesticides, and fertilizers), farms, wheat suppliers, storage silos, processing factories, livestock feed customers, cosmetics and hygiene industries, and flour consumers. To address weather-related disruptions affecting farm output, the model incorporates additional wheat procurement from supplier - considering quantity discounts - as a resilience strategy. Circular economy principles are also considered through selling straw, bran, and damaged grains to cosmetics and hygiene, and livestock feed industries. The objective of the model is to maximize the total profit of the supply chain by determining product flows between different stages, flour production quantities, inventory levels of agricultural inputs, wheat, and flour, supplier selection, and the location and capacity of silos. The model is then applied to a numerical example, and the computational results are presented.
