Heuristics for Multi-Item Two-Echelon Spare Parts Inventory Control Problem with Batch Ordering in the Central Warehouse
We consider a multi-item two-echelon inventory system in which the central warehouse operates under a (Q,R) policy, and each local warehouse implements (S − 1, S) policy. The objective is to find the policy parameters minimizing expected system-wide inventory holding and fixed ordering costs subject to an aggregate mean response time constraint at each facility. We propose a Lagrangian heuristi...
متن کاملAn exact solution procedure for multi-item two-echelon spare parts inventory control problem with batch ordering in the central warehouse
We consider a multi-item two-echelon inventory system in which the central warehouse operates under a (Q,R) policy, and the local warehouses implement basestock policy. An exact solution procedure is proposed to find the inventory control policy parameters that minimize the system-wide inventory holding and fixed ordering cost subject to an aggregate mean response time constraint at each facility.
متن کاملInventory management in a multi-echelon spare parts supply chain
In many industrial sectors, firms are dealing with a demand which is more and more uncertain often due to the supply chain structure. One of the most critical effects of demand uncertainty is the simultaneous increase of inventories and decrease of customer service. This work describes an integrated system for managing inventories in a multi-echelon spare parts supply chain, in which customers ...
متن کاملMulti Echelon Spare Parts Inventory Optimisation: a Simulative Study
The research in this paper is motivated by a real life spare parts networks for complex technical systems in oil refining sector. At the customers the availability of the installed technical systems often is essential for the primary process. Hence, they require a high availability. For improve the management of the spare parts inventory the main company (the customer) has developed a new strat...
متن کاملA Multi-Item Spare Parts Inventory Model with Customer Differentiation
We consider a single warehouse where spare parts of multiple stock-keeping units are kept on stock to serve customers with (close-to-)identical machines. Customers are divided into multiple customer classes, and a target aggregate fill rate is set per class. In order to get differentiated service levels, critical level policies are assumed. We formulate a multi-item, single-stage spare parts in...
