GENERAL SIMULATION MODEL TO IMPROVE THE DESIGN AND OPERATION OF CROSS-DOCKING SYSTEMS

摘要

Cross-docking operations involve receiving and unloading groups of incoming units and then disassembling, recombining each unit into groups that meet outgoing needs, and loading them onto outgoing containers. The primary objective of cross-docking is to reduce storage, handling, and lead time so as to minimize transportation and storage costs and maintain a high level of customer service. This paper focuses on the development and application of a general cross-docking simulation model that is used to understand the stochastic and dynamic behavior of cross-docking systems. It is used to assess the performance of alternative physical arrangements and operational policies. In order to represent the most flexible designs, a key component of the model - a general door object - is presented. It is able to dynamically switch between inbound and outbound functions based on a specified set of operational rules. Example uses of the model are provided.
