3、究的关键。在这一环境下，作为物流的重要组成部分的仓储，也越来越多的被人们关注。如何提高仓储管理效率，成为了现代经济研究的一个热点问题。目前我国仓储管理的卸车验货、入库管理、出库管理、库存管理等几个环节发展不平衡。其中卸车验货、出库管理和库存管理已经达到了比较先进的水平，但是仓储管理中的入库管理却比较混乱。当前大约 80%的配送中心或仓库，在入库管理时不能够进行正确的货位优化，只能凭借管理人员的经验选择货位，摆放货物，导致入库管理效率低下。因此，解决入库管理中的货位优化问题，势在必行。本文在总结现有货位优化成果的基础上，分析了现有货位优化模型的特点，建立了适合我国仓储业的货位优化模型，为解决入库

4、管理中的货位优化问题提供了技术支持。首先对现有货位优化模型的目标及其实现手段进行比较，根据比较结果，选择了本文中货位优化模型的目标和实现目标的手段；其次，建立了货位优化模型的目标函数，并分析了实现货位优化必须满足的约束条件，根据目标函数和约束条件，建立了货位优化模型；再次，应用遗传算法对货位优化模型进行求解；最终，选择邮政易通化妆品仓库作为案例，检验本文建立的货位优化模型。关键词仓储货位；优化模型；遗传算法-I-AbstractWith the world economics integrating and the modern science developing,the modern lo
