碩士 === 國立臺灣科技大學 === 工業管理系 === 105 === To facilitate operation process and improve material flow in warehousing systems, robotic technology is introduced for transportation and system control management in customer order fulfillment and inventory replenishment. This thesis studies the assignment of multiple robotic drive units deployed in the storage area and picking stations for pod transportation in order to minimize the system processing time of customer orders. Mathematical programming is formulated to find the optimal assignment of orders retrieved in picking stations, drive units allocated to serve orders, and item transportation sequence in each drive unit. Due to complexity and enormous computation time in finding the optimal solution, heuristic algorithms are developed to obtain near optimal allocation based on properties observed from the optimal assignment. Numerical experiment is presented to verify output from opt
