In this article, a heuristic recursive optimization/simulation procedure is developed to minimize the total cost of an automated storage/retrieval system (AS/RS) in warehouses and explore the dynamic behavior of such a system.Abstract:
The study of Automated Storage/Retrieval Systems (AS/RS) in warehouses has developed along two main lines: One seeks to minimize total cost of an AS/RS, while the other explores the dynamic behavior of such a system. This study addressing the two issues simultaneously, obtains design parameters for a system that complies with desired levels of performance. To this end, a heuristic recursive optimization/simulation procedure is developed. It is also assumed that the number of stacker cranes (an important cost component of AS/RS) can be less than or equal to the number of aisles. The proposed procedure was applied to several situations, and converged within a few iterations.read more

TL;DR: Throughput capacity models are comprised of picking policies, batching policies, storage assignment policies, as well as dynamic control models, which find the optimal warehouse size or else maximize space utilization.

Optimal Storage Assignment in Automatic Warehousing Systems
TL;DR: It is shown that significant reductions in crane travel time and distance are obtainable from turnover-based rules, and these improvements can be directly translated into increased throughput capacity for existing systems, and may be used to alter the design of proposed systems.

TL;DR: The results indicate that significant reductions in crane travel time and distance are obtainable in some real-world and previously modeled situations via the proposed storage assignment/interleaving policies, which may be directly translated into increased throughput capacity for existing systems.

Scheduling Policies for Automatic Warehousing Systems: Simulation Results
TL;DR: In this article, the authors examined and extended previous analytical work on the scheduling of stacker cranes in automatic warehousing systems by means of a computer simulation, and demonstrated the value of previously-proposed scheduling rules in a dynamic, stochastic environment operating with imperfect information.
