For its power of reducing operational cost without sacrificing customer service level, cross-docking technology has been widely applied in logistics industry and many others. Successful applications in different industries can be found in [1-3]. 对于其功率不牺牲客户服务水平，降低运营成本，交叉对接技术已被广泛应用于物流业和其他许多人。可以发现在不同行业的成功应用[1-3]。

Abundant academic research starts to emerge especially in recent years [4-7]. However, literature to date mainly focuses on either operation scheduling or design optimization of a cross-docking center. Little research has been done to optimize the major performance measures of a cross-docking center, which reflect main advantages of cross-docking technology. The lack of optimization of comprehensive performance measures might lead to misjudging the impacts of cross-docking. An optimal trade-off among operational cost and customer service level serves as the motivation to fill this research gap. 丰富的学术研究，尤其是近年来开始出现[4-7]。然而，文学的日期主要集中在交叉对接中心无论是运行调度的优化设计。小的研究已经做了优化性能的主要措施的交叉对接中心，反映了交叉对接技术的主要优点。缺乏综合性能优化措施，可能导致误判的影响，交叉对接。运营成本和客户服务水平之间的最佳折衷作为填补了这一研究空白的动机。
The complex dynamics of the whole cross-docking system makes the analytical study extremely hard, if not impossible. Discrete event simulation is thus employed here to evaluate the performance measures of such systems. Along with the high modeling flexibility, simulation brings cumbersome computational burden. Other than that, the huge solution search space could be another disaster. To tackle these www.51lunwen.org challenges, a solution framework that integrates genetic algorithm (GA) with smart computing budget allocation (SCBA) method is proposed. 整个交叉对接系统的复杂动力学分析研究非常辛苦，如果不是不可能的。离散事件仿真，因此这里采用这种系统的性能进行评估的措施。随着高建模的灵活性，仿真带来了繁琐的计算负担。除此之外，搜索空间巨大的解决方案可能是另一场灾难。为了应对这些挑战，解决方案框架，将遗传算法（GA）与智能计算的预算分配方法（SCBA）提出。
