Basic Multi-Item, Single-Location Inventory Model

摘要: Chapter 2 is devoted to basic multi-item, single-location inventory models for spare parts. These constitute the basis all other chapters. We start with a model backordered demands and service level constraint in terms of aggregate mean number demands. This measure directly related system availability. For minimization investment parts under this constraint, we formulate greedy heuristic, which shown generate efficient solutions two-objective optimization problem. Next, discuss Lagrangian relaxation Dantzig-Wolfe decomposition as alternative techniques, explain item approach, show how deal measures. Finally, describe variant emergency shipments an waiting time multiple extensions are given.
