We developed a system for managing inventory at Jeppesen Sanderson, Inc., a major provider of aviation-information products. The system determines order quantities for charts used in flight manuals. These charts contain essential safety information that changes frequently, making standard...

Jeppesen Sanderson, Inc. maintains, manufactures, and distributes flight manuals containing safety information for over 300,000 pilots and 400 airlines worldwide. Its service deteriorated when a growing line of over 100,000 aviation charts overwhelmed its production system. We developed...

We introduce a heuristic method for finding good, feasible solutions for multiproduct lot sizing problems with general assembly structures, multiple constrained resources, and nonzero setup costs and setup times. We evaluate the performance of this heuristic by comparing its solutions to optimal...
