| dc.description.abstract | With the rise of on-line shopping market and the liberalization of global economy, the logistics industry has to develop a more efficient model to meet higher customer service level and product quality. Cross docking is one of the strategies of logistics operations. After suppliers transport different kinds of products to distribution center through receiving dock, products will be assigned to different temporary storage area. Then pickers pick the items to tally area according to the orders. Finally, the finished orders will be moved to shipping dock and transported to the customers. In the environment of cross-docking warehouse, the operation of inbound process, storage and examination can be eliminated, therefore the time that products go through from inbound to outbound can be minimized.
This study focuses onDistributor Cross Docking.We investigate put-to-light picking problem under the environment with multi-block tally area storage location layout. We proposefour decision problems“the selection rules of items in temporary area”, “the assignment rule of order storage location in tally area”, “the selection rules of picking location” and “picking route planning.” The data is obtained by simulation software, Arena. We analyze the performance index such as total system time（TST）, total picking time（TPT）and total picking distance（TPD）in our environment. Finally, the best combinations of rules under different performance index are discovered.
It’s observed that the best combination under performance index, TST and TPT, would be NTA× ESOTVMSQCLG. And the best combination under performance index of TPD would beNTASTDMSQCLG, whichcan make the best enhancement in the system.
