A Single-Unit Decomposition Approach to Multiechelon Inventory Systems
We show the optimality of state-dependent echelon base-stock policies in uncapacitated serial inventory systems with Markov-modulated demand and Markov-modulated stochastic lead times in the absence of order crossing. Our results cover finite-time horizon problems as well as infinite-time horizon formulations, with either a discounted or an average cost criterion. We employ a novel approach, ba...

متن کاملDynamic Leadtime Management in Supply Chains
One way to hedge against random fluctuations of demand in supply chains is to keep inventories at various points in the chain. Another is to actually modify the leadtimes in the system dynamically. Working with multiple suppliers, using multiple transportation options, having the option to expedite certain processes, or having different possible routes for a unit to go through the supply chain ...
متن کاملEstimation of the cost function of a two-echelon inventory system with lost sales using regression
Multi-echelon inventory systems are one of the most important and attractive areas in modelling supply chain management so that several researches and studies have been done about. In this paper, the total cost function of a two-echelon inventory system with central warehouse and many identical retailers controlled by continuous review inventory policy is estimated. We have assumed the demand i...
متن کاملIntroducing the Time Value of Money in a Non-consignment Vendor Managed Inventory Model
Vendor managed inventory (VMI) is an integrated approach for buyer–vendor coordination, according to which the vendor (supplier or manufacturer) decides on the appropriate buyer’s (retailer’s) inventory levels. The time value of money has not traditionally been considered in evaluating VMI supply chain’s total inventory cost in any studies up to now. Therefore, in the present study a new model ...
