产品架构可以描述为 :“ 将产品的功能元素排列成物理块以及块之间相互作用的方案”功能性——有助于整体绩效的单个操作和转换.物理–实现产品功能的零件、组件和子组件（通俗来讲，顺序是完成相应功能的零件 component--->组件 chunks---->产品，产品架构就是以实体组件来实现产品的各功能单元，并使各组件相互作用的配置方案） Product Architecture can be described as: 1."the scheme by which the functional elements of the product are arranged into physical chunks and by which the chunks interact” 2.Functional – individual operations and transformations that contribute to its overall performance 3.Physical – parts, components and subassemblies that implement the product’s functions 产品架构可以描述为 :“ 将产品的功能元素排列成物理块以及块之间相互作用的方案”功能性——有助于整体绩效的单个操作和转换.物理–实现产品功能的零件、组件和子组件（通俗来讲，顺序是完成相应功能的零件 component--->组件 chunks---->产品，产品架构就是以实体组件来实现产品的各功能单元，并使各组件相互作用的配置方案） Product Architecture can be described as: 1."the **scheme** by which the functional elements of the product are arranged into physical chunks and by which the chunks interact” 2.**Functional** – individual operations and transformations that contribute to its overall performance 3.**Physical** – parts, components and subassemblies that implement the product’s functions

- ◦ 模块化架构 modular architecture 特点：1.各个组件分别实现一个或多个功能 2.组件之间的关系是明确的，这种关系往往是实现一个产品功能的基础 ·Each chunk implements one or a few functions entirely. ·The interactions between chunks are well defined. ·Modular architecture has simplicity and reusability for a product family or platform. 理解：当每个功能都只被一个组件完成时，并且组件之间的配合十分完美时，这种架构允许在不改变的情况下只改变一组而不影响整体功能。也就是说各个组件可以单独设计 - ◦ 模块化架构 modular architecture 特点：1.各个组件分别实现一个或多个功能 2.组件之间的关系是明确的，这种关系往往是实现一个产品功能的基础 ·Each chunk implements one or a few functions entirely. ·The interactions between chunks are well defined. ·Modular architecture has simplicity and reusability for a product family or platform. 理解：当每个功能都只被一个组件完成时，并且组件之间的配合十分完美时，这种架构允许在不改变的情况下只改变一组而不影响整体功能。也就是说各个组件可以单独设计
- ▪ 槽形模块架构 Slot-modular (the most common type) 每个接口都与于其它接口类型不同，产品中的组件不能互换 Each of the interfaces between chunks in a slot-modular architecture is of a different type from the others – therefore the various chunks in the product cannot be interchanged 例子：汽车上的收音机接口与速度仪、仪表盘的接口都不同 - ▪ 槽形模块架构 Slot-modular (the most common type) 每个接口都与于其它接口类型不同，产品中的组件不能互换 Each of the interfaces between chunks in a slot-modular architecture is of a different type from the others – therefore the various chunks in the product cannot be interchanged 例子：汽车上的收音机接口与速度仪、仪表盘的接口都不同
- ▪ 总线模型 Bus-modular 有一个通用总线，其他组件通过同类型的接口连接到这个总线上 There is a common bus to which the other chunks connect via the same type of interface 例子：轨道照明 - ▪ 总线模型 Bus-modular 有一个通用总线，其他组件通过同类型的接口连接到这个总线上 There is a common bus to which the other chunks connect via the same type of interface 例子：轨道照明
- ▪ 组合型模块架构 Sectional-modular 所有接口都是同类型的，但是没有一个所有组件都与之相联的元件。组装是通过将同样的接口相连接而完成的 1.All interfaces are of the same type, there is no single element to which all the other chunks attach 2.The assembly is built up by connecting the chunks to each other via identical interfaces 例子：分体沙发 - ▪ 组合型模块架构 Sectional-modular 所有接口都是同类型的，但是没有一个所有组件都与之相联的元件。组装是通过将同样的接口相连接而完成的 1.All interfaces are of the same type, there is no single element to which all the other chunks attach 2.The assembly is built up by connecting the chunks to each other via identical interfaces 例子：分体沙发

- ▪ 产品架构的含义 你所做的关于产品架构的决定是有影响的 产品变化 模块化块允许对产品的一些孤立的功能元素进行修改，而不一定影响其他块的设计 改变的动机包括——升级、附加、适应、磨损、消耗、使用的灵活性、重复使用 There are implications to the decisions you make about product architecture ·Product change ·Modular chunks allow changes to be made to a few isolated functional elements of the product without necessarily affecting the design of other chunks ·Motives for change include – upgrades, add-ons, adaptation, wear, consumption, flexibility in use, reuse - ▪ 产品架构的含义 你所做的关于产品架构的决定是有影响的 产品变化 模块化块允许对产品的一些孤立的功能元素进行修改，而不一定影响其他块的设计 改变的动机包括——升级、附加、适应、磨损、消耗、使用的灵活性、重复使用 There are implications to the decisions you make about product architecture ·Product change ·Modular chunks allow changes to be made to a few isolated functional elements of the product without necessarily affecting the design of other chunks ·Motives for change include – upgrades, add-ons, adaptation, wear, consumption, flexibility in use, reuse
- ▪ 积簇 多样性指的是企业在特定时期内根据市场需求所能生产的产品模型的范围 围绕模块化产品架构构建的产品可以更容易地变化，而不会给制造系统增加巨大的复杂性 例如移动电话手机设计、便携式音频 Product variety l Variety refers to the range of product models the firm can produce within a particular time period in response to market demand l Products built around modular product architectures can be more easily varied without adding tremendous complexity to the manufacturing system - ▪ 积簇 多样性指的是企业在特定时期内根据市场需求所能生产的产品模型的范围 围绕模块化产品架构构建的产品可以更容易地变化，而不会给制造系统增加巨大的复杂性 例如移动电话手机设计、便携式音频 Product variety l Variety refers to the range of product models the firm can produce within a particular time period in response to market demand l Products built around modular product architectures can be more easily varied without adding tremendous complexity to the manufacturing system
