需求

As to the material management, the basic theory of material requirement planning is mainly introduced. The features of bill of material, master production schedule and lot sizing of glass deep process industry are analyzed. Then the calculation method of MRP of glass deep process industry is analyzed, and the information integration of cutting stock and MRP isIIrealized.

在物料管理方面，主要介绍了物料需求计划的基本原理，重点分析玻璃深加工企业物料清单、主生产计划、批量规则的特点，分析该行业的物料需求计划的计算方法，实现产品排料与物料需求计划的信息集成。

Actual demand is netted against forecasted demand for a given time period to generate requirements for material planning systems.

某段时期的实际需求与预测需求相比较，以得出物料计划系统需求。

A list containing the quantity and description of all materials required to manufacture or construct a single component, product, or facility. A bill of materials is an essential element in a material requirements planning system.

一份包含所有物料需求数量及名称的清单，乃用来表示一产品是由那些零组件或素材原料所结合而成之组成元素明细，其该元素构成单一产品所需之数量称之为基量，「物料清单」BOM是所有物料需求计划系统系统的一个基础以及必要的要素，如果BOM表有误，则所有物料需求都会不正确。

The research aims to combine with the education practice of the characteristic development of high-end training of Peking University,and discuss the scientific development,design and melioration of high-end training curriculum.

而继续教育的课程是在个体发展与职业岗位需求基础上形成的，课程目标既要针对个人需求又要兼顾组织能力的提升，以个人发展与职业需求并重。

In a two-echelon newsvendor problem, how to incentive the information holder-the retailer to tell the true demand information is provided in discrete and continuous market state. And the optimal cooperation mechanism of supply chain is put forward. Finally, two examples are illustrated.

针对由一个制造商和一个零售商组成二级报童问题，分别从离散需求模式和连续需求模式给出了激励零售商诚实申报需求信息的条件，提出了实现供应链联合最优的激励机制，并用2个实例对合作机制设计进行了说明。

Thirdly, the paper emphatically discusses the role of revenue-sharing contract in the coordination mechanism, which lucubrates this contract by standard newsvendor model in three situations about demand which are stochastic demand, price-sensitive demand, retailer sale-effort dependent demand, and the research result indicates the revenue-sharing contract is a well-behaved cooperation tool and could improve the performance of supply chain.

第三，着重讨论了利益共享契约在供应链协调中的作用，借助于标准的报童模型在三种不同情况下对该契约进行了深入地分析：销售商面临随机的市场需求；需求具有价格敏感性；销售商努力水平影响需求变化，结果表明该契约是一个相对较好的协调工具，可以有效地改善供应链的绩效。

Interpretations vary only concerning to what extent we find shortages in some areas ; to what extent dynamic and long-term views of economic , technological , and social needs might justify an expansion beyond the current demand for graduates ; to what extent uncertainties about the future demand an "overeducation" risk policy ; and to what extent rationales other than labor market demand should be taken into consideration as well .

不同的解释唯一关注的是我们在多大程度发觉某些地区的紧张；动态的和长远的经济、技术、和社会需求的观点在多大程度上超出对毕业生当前需求的扩大；未来不确定的因素在多大程度上需要一个"过度教育"的风险政策；以及理性的而不是劳动力市场的需求在多大程度上被考虑在内。

This paper introduces the concept of automated intelligent tire design as basis, and then systemically presents the general framework of CAD 3-D digital tire model design platform. Its modules include the demand representation, demand preanalysis, product list generation, product list modeling, testing, tires knowledge-base and tire parts-base. The realizing process and key techniques of the product list modeling module are described, including calculation principle of groove section and groove modeling scheme ,and so on. This paper also introduces an improved algorithm of calculating groove centerline. Finally CATIA platform and VBA toolkit-based tire design system is established under detailed demand representation type.

在提出自动化智能轮胎设计概念基础上，系统地阐述了计算机辅助设计三维轮胎数字化模型开发设计平台的整体架构，包括需求表示、需求分析预处理、产品清单生成、产品清单造型、产品检验、轮胎知识库和轮胎零件库等模块；叙述了数字轮胎设计造型模块的实现过程和关键技术，包括花纹沟截面计算原理和各种花纹沟的造型方案等，同时，还提出了一种改进的计算花纹沟中心线的算法；最后基于CATIA三维造型平台和自动化语言VBA二次开发工具实现了在详细需求表示类型下的轮胎设计系统。

In this chapter, a requirement model of customized product based on multi-layer mapping is put forward, and the valid integration of customized requirement information with product structure information has been realized by the mapping relationship between them.

本章提出了基于多层次映射的定制产品需求模型，包括功能层、特征层和实例层，通过建立需求信息同产品结构的层次映射关系，实现定制产品需求表达、获取与产品结构信息的有效集成。
