摘要
以物流配送效益最大化为目标,针对目前城市物流配送中心货车装载率低下以及装载能力有限的条件下多品种货物装配问题进行研究。在系统分析传统构造启发式算法的基础上,综合考虑车辆类型、体积、载重额、客户优先级以及按区域配送线路等约束条件,建立基于ExtendSim的动态仿真模型,进行仿真分析和参数优化设计,使得车辆空间利用率最大,进而解决货物配装过程中存在的车型复杂、包装品种繁多等原因造成的配装困难、配送效率不高以及人工经验主导的配装方法而造成的成本太高等难题。
In order to realize maximum logistics distribution efficiency, the problems existing in current urban logistics distribution center were researched, including low truck loading rate and multi-category goods loading under limited assembling capacity. Based on systematically analyzing the heuristic algorithms of traditional structure, the dynamic simulation model based on ExtendSim was established to carry out simulation analysis and parameter optimization design with comprehensive consideration of constraints including vehicle type, volume, load amount, customer priority and regional distribution lines, which could maximize the vehicle space utilization rate and subsequently solve such problems existing in goods assembling process as difficult loading, low distribution efficiency caused by complicated vehicle type and too many varieties of packaging, as well as the high cost due to experience-based loading methods.
