产品生命周期评价体系研究

为更好地用量化的数据来判断产品的绿色程度，以利于产品生命周期评价，建立了由产品层次维、生命周期维、指标维构成的生命周期评价的三维集成体系结构以及由环境属性指标、资源属性指标、能源属性指标和经济性指标构成的生命周期评价指标体系，并针对评价过程中生命周期权重的确定，产品环境属性数据库的建立以及环境影响因子的确定，给出了有效的解决方法。

Research on the assessment system of product life cycle

The 3D integrated system structure of environmental assessment of product life cycle is presented, whict includes life cycle level, product hierarchy level and factor level, in order to use quantitative data to judge the green degree of product and be propitious to LCA (life cycle assessment) . Furthermore, the factor system of LCA is also built, which is composed of environmental attribute factor, resource attribute factor and economic attribute factor. Moreover, an effective sollution is given for solving the problems during the assessment. The problems include confirming the weight of LCA, building the database of product environmental attribute and giving the evuironmental factor,and so on.
