Optimizing Storage in High-Density Shelving: Studying Item Sizing in Theoretical Shelving Configurations

Abstract

This article is the second in a series exploring approaches to studying the storage density and overall efficiency (as measured in terms of number of items stored) in high-density book storage facilities. It builds on the first in the series by reporting on the measurement of a random selection of materials in the collection as well as initial calculations on item sizing and projections of potential space utilization models using alternate approaches to storage. The study findings extend and confirm the theoretical work of the first article in the series by finding that a width and height-based approach using trays can fit more items than the height-alone approach. At the same time, the research found that space savings varied depending on size and that certain sizes introduced other retrieval issues (e.g., tray weight and maneuverability on upper shelves) and suggest a need to do more detailed analysis of configurations to optimize alternate shelving configuration and use.
