从分析物资经营计划制定过程着手，本着与物资企业的实际情况相一致的原则，建立了多品种、价格有折扣、市场需求随机、经营方式灵活及可以进行仓库租赁的物资经营计划优化模型，然后对建立的模型的特征进行分析，并应用遗传算法对问题进行求解，对物资企业经营有较大的指导意义。

研究了由一个仓库和n个客户（如零售商、批发商等，而非产品最终的消费者）组成的物流配送系统，中央仓库的库存如何经济合理地分配给每个客户，使这个系统整体的性能最优的随机库存/运输联合优化问题。这个分配过程需要同时考虑每个客户的货物量以及最佳的配送路线，库存/运输联合优化问题比单纯的库存问题或单纯的运输问题要复杂得多。研究在随机条件下如何基于FPP思想来求解ITIO问题更具有实用价值。描述了所研究问题的特点，讨论了对随机需求量的近似确定化处理过程，建立了刻画问题特征的数学模型。同时重点论述如何将研究的问题转化为CCLP问题及相应的求解过程，并给出具体的算法步骤。

用数学模型描述了供应商根据某一用户在各个不同时间段内对不同货物的需求量情况, 利用各种不同型号的箱体进行分时段货物发送的问题。其最终目的是为了求得能够使运输成本和存储成本达到最小的货物发送方案, 该问题是一个由批量问题和拼箱问题所组成的复合问题。就此问题, 提出了一种三阶段算法。通过理论分析, 该算法可以有效地解决此类问题。

Urban transpor is not only the problem of how to achieve the aim of effcetive negotiability of citizens and goods, but also an important strategic problem of how to enhance the quality of human inhabitancy condition radically, as well as tie up with urban sustainable development. According to the tendecy and pattern of urban development, this paper demonstrated the development orientation and pattern of Chinese urban transport on the basis of the current situation, and offere the countermeasure form five respects that is integrative strategy, traffic planing, equilibrium of supply and demand, traffic structure optimization, policy formulation.

This paper expands the gypical Vehicle Routing Problem, and synthetically considers the situation of customs with soft time windows and a depot with weveral distrbuting vehicle types. After constructing a mathematical model for the problem, the paper emphasizes the procedure of TS algorthm for solving this problem. Finally, combined with Adaptive Memory procedure, the paper presents tile pseudo-code description of TS algorithm. Some computational results are reported too.
