A coordinated multicommodity (s, S) inventory system

Coordinated and Joint Ordering Policies for Two Commodity Inventory System

ON (s,S) INVENTORY SYSTEM WITH RANDOM LEAD TIME AND REPEATED DEMANDS

We consider an (s,S) inventory system with random lead time and repeated demands of unsatisfied demands from the orbit. Whenever the inventory level falls to the level s, an order is placed to bring the level to S. The quantity ordered is M = S− s. Demands to the system are served immediately if there is a positive inventory. Otherwise it will go to a pool of unsatisfied customers called orbit....

New analytical bounds on the average undershoot in an infinite horizon (s, S) inventory system

We provide new bounds on the average undershoot in an infinite horizon (s, S) inventory system with i.i.d demands with known moments up to order three. The two moment bound improves on Lorden’s bound (Ann. Math. Stat. 1970) for small values of S – s and low values of the coefficient of variation. The three moment bound provides further improvement for negatively skewed demands. The bounds are s...

ing the cost (c(y − x) +K) from revenue, we obtain the total profit f(ξ, x) = r(ξ, y)− c(y − x) −K = 
