“…This paper aims to integrate and advance two streams of literature, which have received significant attention in the pandemic: that of incorporating labor into supply chain network modeling, analysis, and computations (see [16] , [17] , [18] , [19] , [20] ) and problems of human migration, which have been exacerbated under COVID-19 (cf. [21] , [22] , [23] , [24] ). Specifically, in this paper, we construct a supply chain network optimization model that captures the profit-maximizing behavior of a firm with respect to its supply chain network activities of production at multiple sites, the transport of the product to multiple storage sites, the storage at these facilities, and, finally, the ultimate distribution of the product to multiple points of demand.…”
