اشتراک گذاری درآمد یکپارچه و قرارداد تخفیف مقداری برای هماهنگی زنجیره تامین با محصولات چرخه عمر کوتاه

This paper develops a combined contract model for coordinating a two stage supply chain where the demand at the retailer’s end is price sensitive and stock dependent. It has been shown that proposed coordination mechanism achieves perfect coordination and win–win situation for both the members of the supply chain. Further, an extensive sensitivity analysis is performed to examine the impact of various parameters on supply chain performance. It has been found that stock dependency factor has positive impact on order quantity and subsequently on supply chain performance. The paper has also made a comparative statics analysis to see the impact of certain parameters on the pricing and replenishment policies of the retailer.
