摘要
配送系统设计时,除了使系统的总费用最小外,还要满足各需求点对配送时间的要求。在说明了建模的假设条件后,建立了考虑时间约束的多源多品种配送系统模型,并根据模型的特殊结构开发了相应的启发式算法,最后用实际调研的数据作为算例对模型进行了数值演算。
Apart from minimizing the total cost of the system, the design of distribution system should also meet time requirements of the demand points. After listing the assumptions of the model, we built the model for distribution system with multi-source and multi-product based on time constraints. According to the specific configuration, a heuristic algorithm of the model was developed. At the end of this paper, a numerical example was given, in which the data were gained from the fieldwork.
