vendor managed inventory is a continuous replenishment program that is designed to provide major cost saving benefits for both vendors and retailers. previous research on this area mainly included single objective optimization models where the objective is to minimize the total supply chain costs or to maximize the total supply chain benefits. this paper presents a bi-objective mathematical mod...

Abstract This paper studies topological duals of locally convex function spaces that are natural generalizations Fréchet and Banach spaces. The dual is identified with the direct sum another space, a space purely finitely additive measures annihilator $$L^\infty $$ L ? ...
