That is , take the longest production cycle of the products as purchasing and production lead time of the constitutuion of all kinds of materials 即以产品最长生产周期作为构成产品各种物料的采购提前期和生产提前期。
And that the stock and manufacture policy also play an important role in deducing the bullwhip besides the accumulative lead time is concluded 证明了除了累积提前期以外，长鞭效应还与信息共享时的库存、生产控制方式有关。
The over - exaggerating time in advance is the basic reason of high storages of finished and inprocess products and high occupation of current capital 过分夸大的提前期是造成库存和在制品储备高，流动资金占用大的根本原因。
At the same time , this model supposes information on demand during lead time is imperfect and lead time can be controlled and reduced at an added cost 同时，模型假设有关零售商提前期内需求的信息是不完全的，并且提前期可以由追加额外的赶工成本进行控制。
The increasing customer expectation of the shrinkage of lead - time gives urgency and pressure to manufacturers that conduct manufacturing and technological innovation activities 企业客户对交货提前期缩短期望的增强加大了生产企业在技术开发以及生产中的时间紧迫感和压力。
Textile and fashion industry is challenged by many factors , such as rapid changed market demand , global competition , complicated management and lengthen advanced period 纺织服装业面临着瞬息万变的市场需求、全球性竞争、复杂的经营管理、提前期变长而产品生命周期缩短的挑战。
The safety stock exists to cover both excess material consumption within the replenishment lead time and any additional requirements that may occur due to delivery delays 安全库存的存在能够覆盖在一个补货提前期之内的过度的物料消耗，同时也能覆盖可能出现的由于交货延迟导致的任何额外的需求。
We build the expression of total expected annual cost when the demand is normal distribution , simultaneous order quantity , order point and lead time to minimize the total expected annual cost 在市场需求服从正态分布条件下建立年总成本表达式，并同时决策订货量、订货点和提前期使年总成本最小。
According to the defects of the researches dealt with controllable lead time , the authors present a continuous review inventory model with nonlinear lead time crashing cost and lost sale 摘要针对可控提前期领域现有研究的不足，提出基于非线性提前期成本和存在顾客流失情形下，采用连续盘点策略的库存管理问题。
The main problems are also discussed such as order arrangement , capacity , capacity requirement plan , dynamic capacity plan based on agreement synchronous linear produce and lead - time control 讨论了系统所需解决的几个主要问题：订单管理，生产能力和能力需求计划，同步线形生产的能力需求计划的算法，提前期管理。
