Although the Lagrangian method is a powerful dual search method in integer programming, it often fail to identify the optimal solution of the primal problem. In this paper, a quasi dual formulation is proposed for bounded integer programming. This formulation possesses an asymptotic strong...

This paper studies a nonstationary inventory and pricing problem. We consider a two-echelon supply chain with one supplier and two retailers, in which the supplier carries all inventory to supply the retailers. Both the reserved and pooled inventory systems are analyzed. Results with normally...
