(a) Sequential Supply Chain:: (i) Retailer’s profit= Minimum of Demand and Order × Selling Price + Salvage Value × Surplus Product – Order × Whole price paid by the retailer – Fixed Production Cost (ii) Manufacture’s profit= Order × (Whole price paid by the retailer – Variable Production Cost)

(b) Global Optimization: Profit= Minimum of Demand and Order × Selling Price + Salvage Value × Surplus Product – Order × Variable Production Cost – Fixed Production Cost

(c) Buy Back Contract: : Retailer’s Profit= Minimum of Demand and Order × Selling Price + manufacturer buy back price × Surplus Product – Order × Whole price paid by the retailer – Fixed Production Cost

Manufacturer’s Profit= Order × (Whole price paid by the retailer – Variable Production Cost) + Salvage Value × Surplus Product - Surplus Product × manufacturer buy back price

(d) Revenue Sharing: Retailer’s Profit= Minimum of Demand and Order × Selling Price × (1-Revenue Sharing) + Salvage Value × Surplus Product – Order × Whole price paid by the retailer – Fixed Production Cost
Manufacturer’s Profit= Order × (Whole price paid by the retailer – Variable Production Cost) + Minimum of Demand and Order × Selling Price × (Revenue Sharing)
