While there has been a growing number of empirical work on
the quality issue in supply chain management (refer to Li and
Wa r fi eld (2011) for a good characterization), there have been
surprisingly fewer analytical papers on quality modeling in food
supply chain management. Wang and Li (2012) use a pricing
approach based on dynamically identi fi ed food shelf life with the
objectives to reduce food spoilage waste and to maximize food
retailer0 s profi t. Wang et al. (2012) develop a new risk assessment
approach to perform structured analysis of aggregative food safety
risk in the food supply chain by using the concepts of fuzzy set
theory and analytical hierarchy process. In the more general area
of supply chain quality management, Yao and Zhang (20 09)
develop a two-stage leader-follower game theoretic model to
analyze the decisions made by the buyer and supplier with a
quality cost-sharing contract in a supply chain. Wu et al. (2011)
study a two-tier supply chain consisting of a buyer and two
competing suppliers with uncertain product qualities.
