陶瓷产业集聚区陶瓷原料两级配送网络优化模型及算法

为了能在陶瓷产业集聚区为陶瓷企业的生产需求提供及时的陶瓷原料配送服务，提高陶瓷原料配送的规模经济性，需要在区域内建设适当的陶瓷原料配送网络. 本文提出构造陶瓷产业集聚区陶瓷原料两级配送网络，其中第一级配送中心为专业型陶瓷原料配送中心，主要用于满足服务范围内的第二级级陶瓷原料配送中心和部分陶瓷企业的陶瓷原料需求；第二级配送中心是建立于特定陶瓷企业内的陶瓷原料配送中心，主要满足本企业及周边范围内陶瓷企业的陶瓷原料需求. 以最小化建设成本、运输成本、存储成本等费用和不能得到及时服务的需求量为优化目标，建立陶瓷产业集聚区两级陶瓷原料配送网络问题的数学优化模型，并设计了基于模拟退火算法的求解方法. 计算分析表明，该优化方法运算快捷，所得结果合理，及时服务水平与建设节点数目和系统总费用成正比关系，能为陶瓷产业集聚区陶瓷原料配送网络设计提供良好的决策支持.

Optimization Model and Algorithm for Bi-level Distribution Network of Ceramic Raw Materials in Ceramic Industrial Cluster Region

To meet the raw materials distribution demand of ceramic enterprises in the cluster region and improve the scale economic distribution service, the appropriate ceramic raw materials distribution network should be established. The bi-level distribution network in ceramic industrial cluster region is proposed in the paper. The service nodes in the first level are the large and professional distribution centrals, which satisfies the ceramic raw materials demands of the distribution centrals and some ceramic enterprises within theirs service range; The service nodes in second level is the distribution centrals established in some ceramic enterprises, and the ceramic raw materials demands of the itself and some other surround ceramic enterprises are satisfied. The optimization model for bi-level distribution network design is proposed in which the objective function is to minimize the location costs and transportation cost and inventory cost, the service quality is considered at the same time. A solution approach based on the simulated annealing algorithm is developed. Practical application denoted the optimization method operated rapidly and the result is rational. It provides a perfect decision-making support method for the design of ceramic raw materials distribution network in the ceramic industrial cluster region.
