Analysis of inventory level under procurement constraints in supply chain

CHANG Guangshu

Frontiers of Mechanical Engineering 2007, Volume 2, Issue 3, Pages 361-363 doi: 10.1007/s11465-007-0063-1

Abstract: Because the inventory is one of the major factors that affect the performance of the supply chain system, efficient reduction of an inventory can effectively reduce the cost level of the total supply chainConsidering the (, ) policy in an inventory management, this paper establishes a model of the inventory levelThen, the change of the inventory level with and without the procurement constraints is analyzed, andConsequently, the order point can be determined accurately to reduce the inventory level and the operation
