在假定销售价格不同于采购价格的前提下,把传统的延长支付方式归结为两阶段支付,改进了原有的建模方式,提出了连续延迟支付的概念,最后给出了零售商延迟支付条件下的经济批量问题的计算方法,并通过数据实验得出连续支付方式优于两阶段支付方式,并且随着延迟支付时限的增长,两阶段支付与连续支付的差值逐渐缩小,从而为库存管理人员提供了参考依据.

Due to the phenomenon of crane cross--operating in the construction site, in order to meet the needs of safety and management in construction site, against the operational issues for the boom tower cranes, the crane collision detection algorithm is proposed and designed, referencing the idea of the AABB bounding volume hierarchies. The algorithm uses the method of the boundary description to accurately describe the geometrical properties of the tower crane, while introduces the four- dimensional space-time state model and the operational status information to build a mathematical model of the boom crane. The simulation results show that the algorithm can effectively prevent collision between the cranes.
