Abstract
Many of researches on AGV deal with so-called high-performance AGVs that are expected to be expensive. However, if the pathway for such AGVs provides significant part of the means for their intelligent and accurate control, each of the AGVs can be low-cost. In such a case, the cost for preparation of AGV pathway should be suppressed. From this viewpoint, we deal with an optimal pathway layout based on the recursive optimization approach.
