Such a supply chain is a specific case of serial supply chains [27]. Using a sensitivity analysis of two important parameters (deterioration rate and freshness factor ), we draw the conclusion that the more perishable the produce is, the faster the quality of produce decays, and the higher the possibility of cooperation between supplier and retailer is. Jacqueline Austermann is an Assistant Professor at Columbia University and part of the Seismology, Geology and Tectonophysics Division of Lamont-Doherty Earth Observatory.

I ama PhD student in Earth and Environmental Sciences at Columbia University. Another contribution of our work is the design of a combined contract which ensures that both parties are better off by coordinating in a situation where both the effective supply and the market demand of the produce are random; freshness, deterioration rate, and transportation costs are sensitive to time, and market demand is sensitive to freshness level.
