Supply Chain Coordination with Multiple Retailers and Non-Linear Production Costs


Yigal Gerchak,

(Department of Industrial Engineering, Tel-Aviv University) 



We consider coordination with multiple retailers when supplier's production costs are non-linear. The non-linearity of the production costs introduces indirect dependence among the retailers. We consider a fixed retail price scenario, as well as price-dependent linear additive and iso-elastic demands. We explore these scenarios under wholesale-price-only contract, as well as revenue sharing contract. We then consider these models when demand depends on inventory level.

Keywords: coordination; non-linear costs; multiple retailers, inventory-level-dependent demand.
