| 1. | Simulation on the order point of an blood inventory system
大型医院血液库存系统订货点决策的仿真研究 |
| 2. | We can get the quantity of purchase by eoq model , we also can know when we should place order by a function model
订多少货的问题常通过经济订货批量模型解决，而何时订货则是根据数量确定再订货点的一个函数模型。 |
| 3. | Our study arein the inventory management from two ways : ( 1 ) the reorder point ; ( 2 ) make theinventory periodic . in the method of the reorder point , the supplier is often lack of products inthe delivery
在再订货点库存管理法中,由于供应商面对的不止一个客户,往往不能按订单量及时配送商品。 |
| 4. | 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。 |
| 5. | The problems of inventory control mainly comprise the analysis of optimal order time and order number through dynamic programming , and the evaluation of material provider uses models of fuzz complex judge
库存控制问题主要通过动态规划模型来研究物资的最佳订货点及订货批量，而供应商的评价则通过模糊综合评价法实现。 |
| 6. | We proved there ' s a global optimal policy which minimizes the expected total annual inventory cost when the lead time demand is normal distribution and develop effective iterative procedures for finding the optimal solution
证明当提前期需求服从正态分布时，存在唯一的全局最优订货量、订货点和提前期，使年总成本最小。 |
| 7. | The findings are that it is optimal to use base - stock policy . the second section assumes that outer ordering incurs fixed ordering cost , then outer ordering uses ( r , q ) policy , while inner ordering uses base - stock policy
第二节在第一节的基础上，假设外部订货时订购费存在，这时外部订货采用固定订货点、固定订货量( r ， q )策略，而内部订货仍采用前面的基本库存策略。 |
| 8. | The problems of inventory control comprise the forecast of material annual requirement , optimal order time and order number and the analysis of material abc , and mathematics models involve variant index trend , order number and fuzz complex judge etc . finally , this papers gives the requirement analysis and system design of inventory management system , and develops the software of inventory system
库存控制问题主要研究了物资年需求量的预测、最佳订货点及订货批量的研究、物资的abc分析等问题，数学模型重点探讨了可变平滑参数的指数平滑法、订货批量法以及模糊综合评判法等。最后，本论文对库存管理系统进行了需求分析和系统设计，并给出了软件的具体实现。 |
| 9. | According to the analysis on the order point method which is mainly used to manage material stocks for production ， the relationship between the spare part demand plan and order point method is be established . that is to say , in the case of preventive maintenance pattern using the planned spare parts , they have a surprising similarity . so , order point method can be used to design the key software of spare parts dynamic management system
通过对订货点法的分析和研究，得出了备件需求计划与订货点法的关系，即在预防性维修模式使用计划性备件的情况下，备件需求计划与主要适用于生产物资库存管理的订货点法相似，可以用于备件计算机动态管理核心软件的设计。 |
| 10. | According to the demand of the stochastic model of inventory for the single stage , we analyzed modeling methods of multi - stage production / inventory system in hybrid production processes . then we introduced a model of inventory system for multi - stage processes . finally , we introduced an evaluation method for the parameter of the models
为满足多阶段的混合流程生产系统加工成本最小的要求，论文深入研究了生产系统中，多阶段加工情况下成品、在制品和原材料的串行结构库存管理系统整体优化问题，建立了整体库存量控制模型，得出了整体库存的最佳订货量和最佳订货点。 |
