基于相似性与结构敏感性分析的产品平台设计过程模型

建立结构合理的产品平台是实现企业多样化效率和效益的重要途径。从设计角度把产品平台分为概念平台和实体平台,前者组成了产品族创新的核心资源,后者集合了企业产品的核心元件。提出了基于相似性分析与结构敏感性分析的产品平台设计过程模型,并对其中关键环节所涉及的通用化设计规则和方法进行了着重分析。应用该过程模型可以为企业建立更具柔性的层级产品平台架构,设计过程可以分为两个阶段:首先通过功能和概念结构相似性分析以及通用化设计建立产品概念平台;然后通过实体结构对需求变化的敏感性分析和通用化设计建立产品实体平台。最后该模型用于某企业的铠装刮板输送机产品平台的设计。

Product Platform Design Process Model Based on Similarity and Structural Sensitivity Analysis

Building a product platform with rational structure is a good way for a company to obtain variety efficiently and effectively.From the aspect of design the product platform can be divided into conceptual platform and entity platform,the former forms the core resource for innovation of product family,and the latter gathers the core components for variants production.A process model for product platform design based on similarity and structural sensitivity analysis is put forward,as a solution of one of key steps,the rules and approaches for commonality design is put emphasis on.By use of that process model a more flexible product platform with hierarchy architecture can be built.According to that model the design process is separated into two phases.First,the product conceptual platform is designed based on similarity analysis and commonality design on function and conceptual structure units.Second,the product entity platform is designed based on sensitivity analysis for entity units to the changes of customer requirements.As an illustration,the process model is used for product platform design of armored face conveyer of a company.
