1、工业工程之供应链010940835 宫铭所谓供应链,其实就是由供应商、制造商、仓库、配送中心和渠道商等构成的物流网络。同一企业可能构成这个网络的不同组成节点,但更多的情况下是由不同的企业构成这个网络中的不同节点。比如,在某个供应链中,同一企业可能既在制造商、仓库节点,又在配送中心节点等占有位置。在分工愈细,专业要求愈高的供应链中,不同节点基本上由不同的企业组成。在供应链各成员单位间流动的原材料、在制品库存和产成品等就构成了供应链上的货物流。 所谓供应链管理,就是指在满足一定的客户服务水平的条件下,为了使整个供应链系统成本达到最小而把供应商、制造商、仓库、配送中心和渠道商等有效地组织在一起来进行
2、的产品制造、转运、分销及销售的管理方法。 从上述定义中,我们能够解读出供应链管理包含的丰富内涵。 首先,供应链管理把产品在满足客户需求的过程中对成本有影响的各个成员单位都考虑在内了,包括从原材料供应商、制造商到仓库再经过配送中心到渠道商。不过,实际上在供应链分析中,有必要考虑供应商的供应商以及顾客的顾客,因为它们对供应链的业绩也是有影响的。 其次,供应链管理的目的在于追求整个供应链的整体效率和整个系统费用的有效性,总是力图使系统总成本降至最低。因此,供应链管理的重点不在于简单地使某个供应链成员的运输成本达到最小或减少库存,而在于通过采用系统方法来协调供应链成员以使整个供应链总成本最低,使整个供
3、应链系统处于最流畅的运作中。 第三,供应链管理是围绕把供应商、制造商、仓库、配送中心和渠道商有机结合成一体这个问题来展开的,因此它包括企业许多层次上的活动,包括战略层次、战术层次和作业层次等。 尽管在实际的物流管理中,只有通过供应链的有机整合,企业才能显著地降低成本和提高服务水平,但是在实践中供应链的整合是非常困难的,这是因为:首先,供应链中的不同成员存在着不同的、相互冲突的目标。比如,供应商一般希望制造商进行稳定数量的大量采购,而交货期可以灵活变动;与供应商愿望相反,尽管大多数制造商愿意实施长期生产运转,但它们必须顾及顾客的需求及其变化并作出积极响应,这就要求制造商灵活地选择采购策略。因此,
4、供应商的目标与制造商追求灵活性的目标之间就不可避免地存在矛盾。 其次,供应链是一个动态的系统,随时间而不断地变化。事实上,不仅顾客需求和供应商能力随时间而变化,而且供应链成员之间的关系也会随时间而变化。比如,随着顾客购买力的提高,供应商和制造商均面临着更大的压力来生产更多品种更具个性化的高质量产品,进而最终生产定制化的产品。 研究表明,有效的供应链管理总是能够使供应链上的企业获得并保持稳定持久的竞争优势,进而提高供应链的整体竞争力。统计数据显示,供应链管理的有效实施可以使企业总成本下降20%左右,供应链上的节点企业按时交货率提高15%以上,订货到生产的周期时间缩短20%30%,供应链上的节点企
5、业生产率增值提高15%以上。越来越多的企业已经认识到实施供应链管理所带来的巨大好处,比如hp、ibm、dell等在供应链管理实践中取得的显著成绩就是明证。 供应链管理:它从战略层次和整体的角度把握最终用户的需求,通过企业之间有效的合作,获得从成本、时间、效率、柔性等最佳效果。包括从原材料到最终用户的所有活动,是对整个链的过程管理。 scm(供应链管理)是使企业更好地采购制造产品和提供服务所需原材料、生产产品和服务并将其递送给客户的艺术和科学的结合。供应链管理包括五大基本内容。 计划:这是scm的策略性部分。你需要有一个策略来管理所有的资源,以满足客户对你的产品的需求。好的计划是建立一系列的方法
6、监控供应链,使它能够有效、低成本地为顾客递送高质量和高价值的产品或服务。 采购:选择能为你的产品和服务提供货品和服务的供应商,和供应商建立一套定价、配送和付款流程并创造方法监控和改善管理,并把对供应商提供的货品和服务的管理流程结合起来,包括提货、核实货单、转送货物到你的制造部门并批准对供应商的付款等。 制造:安排生产、测试、打包和准备送货所需的活动,是供应链中测量内容最多的部分,包括质量水平、产品产量和工人的生产效率等的测量。 配送:很多圈内人称之为物流,是调整用户的定单收据、建立仓库网络、派递送人员提货并送货到顾客手中、建立货品计价系统、接收付款。 退货:这是供应链中的问题处理部分。建立网络
7、接收客户退回的次品和多余产品,并在客户应用产品出问题时提供支持。定义 供应链管理(supply chain management,scm)是一种集成的管理思想和方法,它执行供应链中从供应商到最终用户的物流的计划和控制等职能。从单一的企业角度来看,是指企业通过改善上、下游供应链关系,整合和优化供应链中的信息流、物流、资金流,以获得企业的竞争优势。 供应链管理是企业的有效性管理,表现了企业在战略和战术上对企业整个作业流程的优化。整合并优化了供应商、制造商、零售商的业务效率,使商品以正确的数量、正确的品质、在正确的地点、以正确的时间、最佳的成本进行生产和销售。 来源 20世纪70年代晚期,keith
8、 oliver通过和skf、heineken、hoechst、cadbury-schweppes、philips等客户接触的过程中逐渐形成了自己的观点。并在1982年金融时代杂志的一篇文章里阐述了供应链管理(scm)的意义,keith oliver曾经认为这个词会很快消失,但“scm”不仅没有消失,还很快地进入了公众领域,这个概念对管理者的采购、物流、操作、销售和市场活动意义匪浅。 演变 供应链至今尚无一个公认的定义,在供应链管理的发展过程中,许多专家和学者提出大量的定义,反映了不同的时代背景,是在不同发展阶段上的产物,可以把这些定义大致划分为三个阶段: 1、早期的观点认为供应链是制造企业中的
9、一个内部过程 2、后来供应链的概念注意了与其他企业的联系 3、最近供应链的概念更加注重围绕核心企业的网链关系,如核心企业与供应商、供应商的供应商乃至与一切前向的关系,与用户、用户的用户及一切后向的关系。 应用 供应链管理主要涉及到四个领域:供应、生产计划、物流、需求。职能领域主要包括产品工程、产品技术保证、采购、生产控制、库存控制、仓储管理、分销管理。辅助领域主要包括客户服务、制造、设计工程、会计核算、人力资源、市场营销。 供应链管理的实施步骤:1、分析市场竞争环境,识别市场机会,2、分析顾客价值,3、确定竞争战略,4、分析本企业的核心竞争力,5、评估、选择合作伙伴 对于供应链中合作伙伴的选择
10、,可以遵循以下原则: 1、合作伙伴必须拥有各自的可资利用的核心竞争力。 2、拥有相同的企业价值观及战略思想 3、合作伙伴必须少而精。 案例 作为中国最大的it分销商,神州数码在中国的供应链管理领域处于第一的地位。在it分销模式普遍被质疑的环境下,依然保持了良好的发展势头,与cisco、sun、amd、nec、ibm等国际知名品牌保持着良好的合作关系。e-bridge交易系统2000年9月开通,截至2003年3月底,实现64亿元的交易额。这其实就是神州数码从传统分销向供应链服务转变的最好体现。本着“分销是一种服务”的理念,神州数码通过实施渠道变革、产品扩张、服务运作,不断增加自身在供应链中的价值
11、,实现规模化、专业化经营,在满足上下游客户需求的过程中,使供应链系统能提供更多的增值服务,具备越来越多的“it服务”色彩。supply chain management open category: intelligent transportation, supply chain management the so-called supply chain, in fact, from suppliers, manufacturers, warehouses, distribution centers and channels, and so constitute a logistics net
12、work. the same enterprise may constitute the different components of this network node, but the situation is different from a corporate network in different nodes. for example, in a supply chain, companies may not only in the same manufacturers, storage nodes, and in distribution centers, such as po

16、 in the process of the cost implications of various members of the unit are taken into account, including from raw material suppliers, manufacturers to the warehouse distribution center to another channel. however, in practice in the supply chain analysis, it is necessary to consider the suppliers s
17、uppliers and customers of the customers, because their supply chain performance is also influential. second, supply chain management is aimed at the pursuit of the whole supply chains overall efficiency and cost effectiveness of the system as a whole, always trying to make the total system cost to a
18、 minimum. therefore, the focus of supply chain management is not simply a supply chain so that members of the transportation costs to minimize or reduce inventory, but through the use of systems approach to coordinate the supply chain members so that the entire supply chain total cost of the minimum
19、 so that the whole supply chain system in the most fluent in the operation. third, supply chain management is on the suppliers, manufacturers, warehouses, distribution centers and organically integrate the channel into one to start this problem, so many businesses, including its level of activities,
20、 including the strategic level, tactical and operational level level, and so on. although the actual logistics management, only through the organic supply chain integration, enterprises can significantly reduce costs and improve service levels, but in practice the supply chain integration is very di
21、fficult, it is because: first of all, in the supply chain there are different members of different and conflicting objectives. for example, providers generally want manufacturers to purchase large quantities of stable, and flexible delivery time can change; desire to the contrary with suppliers, alt
22、hough most manufacturers are willing to implement long-term production operations, but they must take into account the needs of its customers and to make changes positive response, which requires manufacturers choice and flexibility in procurement strategy. therefore, suppliers and manufacturers to
23、the goal of flexibility in the pursuit of the objectives inevitably exist between the contradictions. secondly, the supply chain is a dynamic system, with time and constantly changing. in fact, customers not only demand and supply capacity to change over time, supply chain and the relationship betwe
