8.比较联合库存管理思想与多级库存管理思想之间的异同点。
9.供应链库存管理中涉及的成本主要包括哪些?讨论案例江铃发动机:探索全新汽配供应链王宗阳是生产发动机活塞簧的南平华闽公司副总裁,对于华闽蒸蒸日上的整车配套OE 业务王宗阳非常满意,但对于供应商必须压货三个月或者更长时间的整车配套供应链规则却不能说太满意。
在目前的整车OE供应链中,整车厂和一级供应商为了自己的零库存和低成本,都采用把库存全部转嫁到下级供应商的做法,于是在各个汽车厂或发动机厂附近建外库并备上三个月或者更长时间的库存成了华闽这样的汽配企业的负担。
库存也意味着企业资金的无效占压,即使“三个月甚至更长”成为汽配行业统一默认的“潜规则”,仍然意味着华闽这样的上游汽配厂不小的负担。
不过,这样的情况正在悄然发生变化。
江铃发动机采用了一种更加协同的供应链,它已经开始实施由第三方物流进行供应链管理的第三方物流直送工位模式,并将自己6个月内的生产计划通过供应链平台与上游供应商进行协同。
如何解释江铃发动机在供应链模式探索上的改变呢?汽车行业专家指出,用更协同、科学的供应链方式取代旧有不透明、不平等模式其实是汽车行业发展的需要,因为目前的整车OEM配套有一个鲜明的趋势,就是越来越紧密的合作和战略性结合的上下游关系。

additive and multiplicative binomial representations of uncertainty.Answer : The binomial representation of uncertainty is based on the assumptionthat when moving from one period to the next, the value of the underlying factor(such as demand or price) has only two possible outcomes - up or down. In thecommonly used multiplicative binomial, it is assumed that the underlying factoreither moves up by a factor u > 1 with probability p, or down by a factor d < 1 with probability 1 –p. In the additive binomial, it is assumed that the underlying factorincreases by u in a given period with probability p and decreases by d withprobability 1 –p. The multiplicative binomial cannot take on negative values andcan be used for factors like demand, price, and exchange rates that cannotbecome negative. It also has the advantage of the growth or decline in the givenfactor being proportional to the current value of the factor and not fixedindependent of size. A logical objection to both the multiplicative and additivebinomial is the fact that the underlying factor takes on only one of two possiblevalues at the end of each period. Certainly a price can change to more than justtwo values. But by making the period short enough, this assumption may bejustified.Difficulty: Hard2.Summarize the steps in the decision tree analysis methodology.Answer: The decision tree analysis methodology is summarized as follows:1.Identify the duration of each period (month, quarter, etc.) and the number ofperiods T over which the decision is to be evaluated.2.Identify factors such as demand, price, and exchange rate, whose fluctuationwill be considered over the next T periods.3.Identify representations of uncertainty for each factor; that is, determinewhat distribution to use to model the uncertainty.4. Identify the periodic discount rate k for each period.5.Represent the decision tree with defined states in each period, as well asthe transition probabilities between states in successive periods.6. Starting at period T, work back to Period 0, identifying the optimal decision andthe expected cash flows at each step. Expected cash flows at each step in a givenperiod should be discounted back when included in the previous period. Difficulty:Moderate3.Discuss the ideas that managers should consider to make better supply chainnetwork design decisions under uncertainty.Answer: Managers should consider the following ideas to help them make betternetwork design decisions under uncertainty:1. Combine strategic planning and financial planning during network design.Inmost organizations, financial planning and strategic planning are performedindependently. Strategic planning tries to prepare for future uncertainties butoften without rigorous quantitative analysis, whereas financial planning performsquantitative analysis but assumes a predictable or well-defined future. Decisionmakers should design supply chain networks considering a portfolio of strategicoptions —the option to wait, build excess capacity, build flexible capacity, signlong-term contracts, purchase from the spot market, and so forth. The variousoptions should be evaluated in the context of future uncertainty.2. Use multiple metrics to evaluate supply chain networks.As one metric canonly give part of the picture, it is beneficial to examine network design decisionsusing multiple metrics such as firm profits, supply chain profits, customerservice levels, and response times. Often, different metrics will recommenddifferent decisions and by using multiple metrics, the differences between thestrategic choices will become clearer. The best decisions can be made when amultitude of metrics are available, because each metric enhances the overallview of the alternatives being considered.e financial analysis as an input to decision making, not as the decision-making process. Financial analysis is a great tool in the decision-making process,as it often produces an answer and an abundance of quantitative data to back upthat answer. However appealing this may be, management should not rely solelyon financial analysis to make decisions. Use of this analysis as a large part of thedecision-making process is fine, but other inputs into the decision process that aredifficult to quantify should be included in the analysis as well. Financialmethodologies alone do not provide a complete picture of the alternatives. Theseimpacts should be considered in addition to the raw financial analysis. In the finalanalysis, management must use other inputs beyond financial analysis in thedecision-making process to get the most complete view of the alternatives possible.4. Use estimates along with sensitivity analysis. Many of the inputs into financialanalysis can be difficult, if not impossible, to nail down in a very accurate fashion.This can cause financial analysis to be a long and drawn out process. One of thebest ways to speed the process along and arrive at a good decision is to useestimates of inputs when it appears that finding a very accurate input would take aninordinate amount of time.

供应链管理课后习题答案第一章、供应链管理导论1.供应链的结构特征是什么?将供应商、制造商、分销商、零售商、直到最终用户连成一个整体的功能网链结构。
2.何谓供应链管理?简述供应链管理与传统企业管理的区别和联系。
供应链管理就是使以核心企业为中心的供应链运作达到最优化,以最低的成本,另供应链从采购开始,到满足最终用户的所有过程,包括工作流、实物流、信息流、资金流等均高效率运作,把合适的产品,以合理的价格,及时准确的送到消费者手中。
区别:①传统企业的运营思想是生产是为了销售,而供应链企业运营的思想是按订单准时生产、快速响应客户需求②传统企业的管理手段是控制库存、降低库存成本,而供应链管理的手段是供应链企业协同创新、共创价值③传统企业提高生产效率的主要方法是扩大批量、增加规模效应,而供应链企业提高效率的主要方法是提升企业的柔性和敏捷性联系:供应链管理主要是以物流运行作为流程的,是开放性的,传统企业只是供应链管理中的一个环节,是闭环的。
3.供应链管理的关键在于实现企业内部及企业之间资源的集成。
从这个角度,分析互联网在供应链管理中的重要地位。
从管理难度的角度:现在的客户关系管理、企业资源计划等系统使得管理更加容易,尤其是对于一些全球性企业和跨区域企业从效率的角度:通过IT系统,从客户需求到计划、采购、生产、运输等供应链的整个过程更加迅速、高效。
当然也包括上下游企业和核心企业之间的沟通。
从成本的角度:管理难度下降,效率提升,这实际上降低了企业的成本4.电子商务将成为21世纪最主要的商业模式之一,它将对企业传统的业务流程带来巨大变革。
请阐述供应链管理对我国企业成功实施电子商务的重要意义。
基于电子商务的供应链的管理的主要内容涉及订单处理、生产组织、采购管理、运输与配送管理、库存管理、客户服务、支付管理等,供应链管理可促进电子商务的发展,使资源在供应链网络中合理流动,来缩短交货周期、降低库存,并且通过提供自助交易的自助式服务以降低成本,提高速度和精确性,增强企业竞争力。

高级经济师-工商管理-章节练习-第六章供应链管理
高级经济师-工商管理-章节练习-第六章供应链管理[问答题]1.供应商管理库存有哪些原则?正确答案:详见解析参考解析:(1)合作性原则(合作精神)。
实施供应商管理库存,共享信息和信息透明(江南博哥)是很重要的,供应商和用户都要有较好的合作精神,才能够保持较好的合作关系。
(2)互惠原则(使双方成本最小)。
供应商管理库存解决的不是关于成本如何分配或者谁来支付的问题,而是通过实施供应商管理库存使双方的成本都得到减少,双方都受益。
(3)目标一致性原则。
双方都要在观念上达成一致目标。
例如,库存放在哪里、什么时候支付、是否要支付管理费、要花费多少等问题都需要双方达成一致并体现在目标框架协议中。
(4)总体优化原则。
供需双方共同努力消除浪费并共享收益。
[问答题]3.订单驱动的采购方式有哪些特点?正确答案:详见解析参考解析:①由于供应商与制造商建立了战略合作伙伴关系,办理供应合同的手续大大简化,不再需要双方询盘和报盘的反复协商,交易成本也因此大为降低;②在同步化供应链计划的协调下,制造计划、采购计划、供应计划能够并行进行,缩短了用户响应时间,采购与供应的重点在于协调各种计划的执行,使制造计划、采购计划、销售计划保持同步;③采购物资直接进人制造部门,减少采购部门的工作压力和不增加价值的活动,实现供应链的精细化运作;④信息传递方式发生变化,供应链管理环境下供应商能共享制造商的相关信息,提高供应商应变能力,减少信息失真,同时在订货过程中不断进行信息反馈,修正订货计划,使订货量与需求量保持较高的一致性。
[问答题]4.简述物流运作模式该如何选择?正确答案:详见解析参考解析:1.如果物流在企业战略中起关键作用,但自身物流管理水平却较低,对这类企业来说,组建物流联盟将会在物流设施、运输能力、专业管理技能上受益极大;2.对物流在其战略中不占关键地位,但其物流水平却很高的企业来说,可以寻找伙伴共享物流资源,通过增加物流业务获得规模效益,降低成本;3.如果企业有很高的客户服务需求标准,物流成本占总成本的比重极大,自身物流管理能力强,一般不会选择外购物流服务而采用自营方式;4.对于那些物流在其战略中地位并不是很重要、自身物流管理能力也比较欠缺的企业来说,采用第三方物流是最佳选择,因为这样能大幅度降低物流成本,提髙物流水平。

Explain additive and multiplicative binomial representations of uncertainty.Answer: The binomial representation of uncertainty is based on the assumptionthat when moving from one period to the next, the value of the underlying factor(such as demand or price) has only two possible outcomes - up or down. In thecommonly used multiplicative binomial, it is assumed that the underlying factoreither moves up by a factor u > 1 with probability p, or down by a factor d < 1 with probability 1 – p. In the additive binomial, it is assumed that the underlying factor increases by u in a given period with probability p and decreases by d withprobability 1 – p. The multiplicative binomial cannot take on negative values and can be used for factors like demand, price, and exchange rates that cannotbecome negative. It also has the advantage of the growth or decline in the given factor being proportional to the current value of the factor and not fixedindependent of size. A logical objection to both the multiplicative and additivebinomial is the fact that the underlying factor takes on only one of two possiblevalues at the end of each period. Certainly a price can change to more than justtwo values. But by making the period short enough, this assumption may bejustified.Difficulty: Hard2. Summarize the steps in the decision tree analysis methodology.Answer: The decision tree analysis methodology is summarized as follows:1. Identify the duration of each period (month, quarter, etc.) and the number ofperiods T over which the decision is to be evaluated.2. Identify factors such as demand, price, and exchange rate, whose fluctuationwill be considered over the next T periods.3. Identify representations of uncertainty for each factor; that is, determine whatdistribution to use to model the uncertainty.4. Identify the periodic discount rate k for each period.5. Represent the decision tree with defined states in each period, as well as thetransition probabilities between states in successive periods.6. Starting at period T, work back to Period 0, identifying the optimal decision andthe expected cash flows at each step. Expected cash flows at each step in agiven period should be discounted back when included in the previous period.Difficulty: Moderate3. Discuss the ideas that managers should consider to make better supply chainnetwork design decisions under uncertainty.Answer: Managers should consider the following ideas to help them make betternetwork design decisions under uncertainty:1. Combine strategic planning and financial planning during network design. Inmost organizations, financial planning and strategic planning are performedindependently. Strategic planning tries to prepare for future uncertainties butoften without rigorous quantitative analysis, whereas financial planning performsquantitative analysis but assumes a predictable or well-defined future. Decisionmakers should design supply chain networks considering a portfolio of strategicoptions—the option to wait, build excess capacity, build flexible capacity, signlong-term contracts, purchase from the spot market, and so forth. The variousoptions should be evaluated in the context of future uncertainty.2. Use multiple metrics to evaluate supply chain networks. As one metric canonly give part of the picture, it is beneficial to examine network design decisionsusing multiple metrics such as firm profits, supply chain profits, customer servicelevels, and response times. Often, different metrics will recommend differentdecisions and by using multiple metrics, the differences between the strategicchoices will become clearer. The best decisions can be made when a multitudeof metrics are available, because each metric enhances the overall view of thealternatives being considered.3. Use financial analysis as an input to decision making, not as the decision-making process. Financial analysis is a great tool in the decision-making process, as it often produces an answer and an abundance of quantitative data to back up that answer. However appealing this may be, management should not rely solely on financial analysis to make decisions. Use of this analysis as a large part of the decision-making process is fine, but other inputs into the decision process thatare difficult to quantify should be included in the analysis as well. Financialmethodologies alone do not provide a complete picture of the alternatives. These impacts should be considered in addition to the raw financial analysis. In the final analysis, management must use other inputs beyond financial analysis in thedecision-making process to get the most complete view of the alternativespossible.4. Use estimates along with sensitivity analysis. Many of the inputs into financialanalysis can be difficult, if not impossible, to nail down in a very accurate fashion.This can cause financial analysis to be a long and drawn out process. One of the best ways to speed the process along and arrive at a good decision is to useestimates of inputs when it appears that finding a very accurate input would takean inordinate amount of time. Using estimates is fine when the estimates arebacked up by sensitivity analysis. By performing sensitivity analysis on the input’s。

《全球采购与供应链管理》第六章思考题
第六章战略采购管理【本章思考题】参考答案1、战略采购为全球采购活动提供了哪些管理流程?答:第一,对采购需求、全球采购市场和供应商进行研究;第二,对物料、供应商和库存进行分类;第三,寻找、选择和评审全球供应商;第四,开展全球商务谈判;第五,发展和淘汰全球供应商。
2、ABC分类时为什么要对表6-1第4列“2017年10月物料成本”进行降序排列?答:对物料的采购成本或库存成本按照金额由大到小进行降序排列,能保证对采购成本或库存成本中较大项的累加百分比在80%以下。
因为一般约定,累加百分比值80%以下属于A区(对采购成本或库存成本影响最大的项),80%-95%属于B区,95%以上属于C区(对采购成本或库存成本影响最小的项)。
3.怎样提高我们在全球采购谈判中的主导权及优势地位?答:首先应在做好充分的谈判准备工作后,再行开展谈判。
谈判前的准备工作包括:(1)为自己建立谈判的目标,计划好可做出的让步。

三、案例分析
某电脑经销商代销某品牌电脑,按主流配置主要使用3种处理器、3种内存和3种硬盘,一共可组装出27种型号的整机。
这27种型号整机的需求特征相似
且相互独立,月销售量均值为50台,标准差为10台,单价5000元左右,单次订购成本5000元,库存持有成本率12%,订货提前期为1个月。
目前经销商按整机采购,为了尽量避免缺货,给每种机型都设置了10台安全库存量,并采用连续检查的定量订货策略。
经营了一段时间之后发现,一方面,销售常常发生某个型号的缺货,而仓库中却几乎总有一千多台库存,占用了大量资金、存货空间,且盘点工作量巨大。
经过对销售数据的分析,发现各个机型的需求均值和标准差并无变化,排除了某些机型更畅销的猜测,可是却无法解决一手缺货,一手积压的困境。
另一方面,上游厂商开始抱怨经销商的订货时间太不规律,而且几乎每次只批量订购一种型号的机型,给备货和发货带来很多不确定性。
请从库存管理和补货策略方面为该经销商提出一些改进建议。
案例解析:
该经销商面对27个SKU的独立需求设置安全库存,则这是27个相互独立的安全库存,10台安全库存大概满足84%的现货供应率,采用连续检查,只要有哪个机型的库存量低于60台(根据ROP计算公式得知)就下达采购订单,每种机型每次按经济订货批量采购100台(根据EOQ计算公式得知)。
84%的现货供应率会常发生缺货,虽然有库存但型号不对也不能替代,所以一手缺货一手积压。
针对这个问题建议经销商改整机补货为组件补货,分别采购3种处理器、3种内存和3种硬盘,即9种组件,使用相同的机箱,按客户订单进行组装,因为这种组装非常简单,客户几乎是立等可取,与现货供应差别不大,这样可以减少库存品类,减轻盘点工作量。
且这样每种组件都在9种机型中出现,则组件需求的均值为450,标准差为30,保持同样的客服服务水平需保有每个组件30个安全存,即共270个,可以支持组装90台整机,与之前27个机型每个机型10台安全库存比起来,安全库存水平缩减为三分之一。
对于供应商抱怨的问题可以通过改连续检查为周期检查方式,每月检查一次,统一补货(1+1)*450+30=930件,统一发货有利于供应商操作,还可以此与供应商商量价格折扣。
另外还可以进一步与供应商共享需求信息,尝试采用VMI等供应链库存管理方式,以进一步降低库存、避免缺货。
