Abstract

The library users’ experience depends on the library’s performance on their operations. Material handling processes are crucial to improve those library’s operations and service levels, assuring books and items availability. Even if a flow of research has flourished into implementing new solutions, e.g. Autonomous Mobile Robots (AMRs), in response to operational challenges that limit library performance, scientific literature still lacks modeling such solutions. Hence, this study aims to investigate such solutions and their impact on improving the overall performance of library logistics operations.
With the Trondheim Public Library as a case study, several scenarios are analyzed. We considered two layouts: centralized and decentralized with different modes to transport the materials: manual and AMRs. We modeled the scenarios through Queueing Theory. For manual movements, we used Open Queueing networks (OQN), while scenarios used with AMRs are Semi-open Queuing networks (SOQN). SOQN has shown promising applicability in similar contexts to support the decision-making processes for planning and controlling the material flow. The proposed Queueing networks are validated through simulation.
Based on this and varying critical parameters such as flow volume, intensity, variability, library layout, and operational modes, we obtain performance measures to characterize the analyzed scenarios for library logistics operations as well as the advantages and disadvantages.
