机电产品的回收特性关系到资源循环及可持续发展等战略问题，以往的研究大多集中在面向回收的设计与评价，如何准确快捷地获取产品未端的回收信息是制约产品回收效率的瓶颈。本课题以RFID为载体，利用本体论构建机电产品的回收信息模型及语义关联，并对回收信息决策方法进行研究。具体研究包括：（1）根据机电产品生命周期信息的演化规律，研究基于RFID的机电产品的回收信息系统的架构及实现方法，提出RFID的事件语义模型及处理机制，创建基于RFID的上下文语义驱动模型；（2）针对机电产品回收信息结构多样及语义的异构性，利用本体论构建机电产品的回收信息模型与回收方案模型，为回收决策提供语义支持；（3）研究基于CBR的回收检索与及回收综合决策方法，对产品的回收进行综合决策，指导产品的回收。项目的研究对提高机电产品的回收效率，促进再生利用，发展循环经济等具有重要意义。

Recycleability of Electromechanical Products plays a important role in resources recycling,strategy of sustainable development and ecological envirionmental protection. Most of current researches focus on Design for Recycling and Evaluation, the research findings can not be used efficiently for the practical production recycling. How to identify and acquire the recycling information is "bottleneck" for product recycling. This project will focus on building product recycling information semantic model and developing product recycling information system based on Ontology and RFID.It includes three units.(1)According to electromechanical product's evolving law, RFID will be used to construct the product information system, its framework and implementation, RFID semantic event mdoel and event processing mechanism will be studied as well. (2) The information related to electrochemical product recycling is diversiform and heterogeneous, Ontology will be used to built the product information semantic model and product recying scheme model this project, which can supoort the semantic reasoning and faciliate recycling decision . Through Ontology, Context relationship between RFID and product recycling information will be built. (3)CBR will be used to search product recycling scheme and the recycling evaluating tools, such as 3R,LCA,Economic Assessment, Technical Assessment,etc.will be integrated to support the comprehensive decision system of product recycling information. Reseach findings of this project will be helpful to enhance product recycling efficiency, improve reusage of EOL electromechanical Products and develop recycling economy.
