Book Description
The purpose of this project was to design and simulate a high-rise pallet facility for a defense depot. The high-rise storage structure utilizes Storage and Retrieval (S & R) machines for performing picking and stowing operations. Automatic Guided Vehicles (AGVs) are used for transporting loads to and from the storage structure. A simulation model was developed to mimic the dynamic elements of both the S & R and AGV systems. The model was used to evaluate the size and scope of the system, how operating policies would affect performance, trouble areas or possible bottlenecks and the utilization of the equipment. The task required that separate models for the storage and retrieval system and the transport system be written and integrated. The model for the storage & retrieval system was written in FORTRAN and simulates an orderpicking operation. Several unique features were incorporated, including sequencing and batching of orders, variation in the stacking height for each storage level, and movement of S & R machines. S & R machines were allowed to move freely within their assigned bays although only one S & R machine was permitted in an aisle at a time. An AGV transport system model was generated using both FORTRAN functions and SLAM network statements provided in the Material Handling (MH) extension package. The control points, segments of the guidepath, and the AGV specifications were all input as resource blocks. (FR).
