Load shuffling algorithms for split-platform AS/RS
Although automated storage/retrieval Systems (AS/RS) allow random access to any storage cells, often it is advantageous to pre-sort the loads to minimize the retrieval time. In this paper, we address the issue of load shuffling on a new type of AS/RS (i.e., the split-platform AS/RS), which have separate and independent mechanisms for horizontal and vertical movements. We present the shuffling algorithms for such AS/RS, and analyze the required shuffling time and retrieval time. Results from these analysis and numerical experiments show that the shuffling algorithms presented are indeed quite efficient.
