Abstract :
Reviews important input, output, and model integration factors to consider when developing detailed flexible models of AGV (automatic guided vehicles) and ASRS (automated storage and retrieval systems). Examples are presented for setting up a model using the SIMAN simulation language, with Fortran enhancements. The design and development of an AGV and ASRS simulation that provides for the required input and output characteristics result in a model system that is both flexible and comprehensive. AGVs and ASRS cranes can be added or removed. AGV and ASRS path segments and routes can be easily modified or additional ones can be incorporated. Loads can be assigned to ASRS bays by load type, and inventory initialization levels can be easily revised. Material transporter equipment specifications can be readily modified. Capturing the output data, in addition to pertinent facility production data, allows thorough system performance analysis. If other parameters are found to be significant, the statistical and trend output data generated are easily expandable
