Focusing on discount promotion in retailer and stochastic customer demand with price-sensitive, the paper brings forward coordinated replenishment and pricing model that simultaneously determines market price and order quantity. The aim is to maximize expected profit in selling period. The model is proved that it is concave function on price and order quantity and its optimal solution is found out...
Focusing on customer's purchase character of pursuing low price and high quality, the paper considers stochastic demand dependent on price and quality and brings forward joint replenishment and pricing decision model whose endogenous decision variable is market price and order quantity. The model is proved that it is concave function on price and quantity and its optimal solution is found out. The...
