  abstract =     "In this paper, we solve two problems in a 300-mm wafer
                 fabrication facility (fab). Firstly, for the lot
                 scheduling problem, we propose a multi-objective
                 genetic programming based rule generator (MOGPRG) to
                 evolve useful dispatching rules, which can provide
                 near-optimal lot schedules concerning multiple
                 objectives. Secondly, the overhead hoist transports
                 (OHT) routing problem is considered. As the modern
                 automated material handling system (AMHS) is capable of
                 doing tool-to-tool direct delivery, the congestion of
                 OHTs may happen more often than the past. To deal with
                 the traffic congestion in AMHS, a dynamic routing
                 method is proposed to find the near-shortest and
                 less-congested path for the OHT to travel along. It can
                 reduce the traffic congestion and achieve fast lot
                 delivery by adapting to the dynamic traffic
                 environment. The proposed MOGPRG is integrated with the
                 dynamic routing method to improve two fab performance
                 metrics: mean cycle time and tardy rate. Experimental
                 results show the effectiveness of the proposed MOGPRG
                 and dynamic routing method.",
