产品生命周期评价原型系统设计和开发

为了满足产品生命周期动态评价的需要，掌握以生命周期评价为中心的环境信息资源，开发了一套基于客户端／浏览器体系结构的产品生命周期评价原型系统。利用Java和SQL Server 2000技术，从软件设计和开发的角度提出了系统的总体设计目标和基本原则，阐述了系统的总体结构设计。该系统包括产品系统建模、数据处理模块、数据计算模块和影响评价等4个子模块，详细介绍了各子模块的设计和功能特点，以及数据库和用户控制界面的设计。应用实例表明，该系统能为产品系统评价提供必要的技术支持，是一个功能较完善、适用面较广的生命周期评价原型系统。

Design & development of prototype system on product lifecycle assessment

To satisfy requirements of dynamic assessment in product lifecycle and master the lifecycle assessment-centered environmental information resources, a Client/Server structure-based of Product LifeCycle Assessment Prototype System (PLCAPS) was developed. By application of Java and SQL(structured query language) Server 2000 technologies, the general design objectives and basic principles of PLCAPS were described and the overall architecture was explained from viewpoints of software design and development principles. The system was mainly composed of four subsystems: product systematic modeling, data processing module, data calculation module and influence assessment module. The design & functions of each module, and database & user interface were introduced in detail. Finally, an application example indicated that the proposed system could provide essential support for product system assessment with perfect functions and wide applicability.
