The use of Multi-Load AGV (AGV capable of simultaneously transport two Lots with different pick-up and drop-off points) that can significantly enhance operation efficiency of the conventional AGV (Single-Load AGV able to only handle one Lot at a time) is increasing. However, indices for the transportation of Multiple-Load AGV Lot remain unchanged from those for the conventional Single-Load AGV carrying a single Lot, resulting in difficulties to accurately analyze transportation effectiveness of Multiple-Load AGV and troubles to use the indices as a mean to set future direction for additional research. This paper proposes indices to understand transportation and operation effectiveness of Multiple-Load AGV, and based on the new indices, presents a calculation algorithm. Furthermore, it compares the results of the old index calculation method with the new one to analyze the effectiveness of improved algorithm.
