A deteriorating food preservation supply chain model with downstream delayed payment and upstream partial prepayment

This paper investigates a food supply chain model consisting of the supplier, producer and multi-retailer deteriorating item under fully delay-in-payment partial advance payment scheme. The deterioration rate raw material is dependent on temperature other environmental factors with respect to time. Here, prepares after collecting from supplier then storing it in cold storage. refrigeration cost occupied volume storage (where products are preserved for freshness) power consumption. offers stimulate buy more (which minimizes holding earns revenues), whereas takes purchase retailers ensure order quantity. A mathematical developed obtain optimal production time number deliveries so that average profit maximum. Finally, numerical example sensitivity analysis key parameters provided illustrate test feasibility proposed model.
