设计阶段是产品开发中最关键的步骤之一。在这里，必须考虑很多因素，例如技术、功能、美学或经济标准。最近，人们对环境方面的日益关注增加了被称为生态设计的过程的复杂性。在这方面，基于模糊偏好规划方法的特点和模糊逻辑推理，提出了一个整合定量环境指标提供的标准的框架。结果，获得了综合生态设计指数（EcoInd）。这个想法使得流程和产品级别的决策能够同时考虑不同的指标。以儿童鞋类的生态设计为案例研究，开发了包括环境指标估算及其集成的生态设计工具（决策支持系统）。我们对不同型号的鞋子进行了分析，以确定最环保的设计并测试该工具。本例中，选择生态足迹和危害商数和癌症风险两项环境风险评估指标作为相关环境指标，并根据鞋类制造商提供的数据进行计算。然后，将这些指标整合到生态设计工具中，并对所分析的童鞋型号进行生态指数评估。根据这些数字，它们的排名为红色皮革 > 白色皮革 > 白色合成材料 > 粉色合成材料，从最好到最差。
The design stage represents one of the most critic steps for product development. Here, a great number of considerations have to be borne in mind, e.g., technical, functional, aesthetic or economic criteria. More recently, the increasing concerns on environmental aspects have added complexity to the process, known as ecodesign. In this respect, a framework to integrate the criteria provided by quantitative environmental indicators has been proposed on the basis of Fuzzy Preference Programming method features and fuzzy logic reasoning. As a result, an integrated Ecodesign Index (EcoInd) is obtained. This idea enables the decision making at process and product level taking into account different indicators at a time. The ecodesign of children's footwear was taken as case study and an ecodesign tool (decision support system) that included the estimation of environmental indicators and their integration was developed. Different models of shoes were analyzed to identify the most environmentally friendly design and to test the tool. In this case, the Ecological Footprint and two Environmental Risk Assessment indicators, namely Hazard Quotient and Cancer Risk, were selected as relevant environmental indicators and they were computed from data provided by a shoes manufacturer. Then, these indicators were integrated in the ecodesign tool and theEcoIndvalues were appraised for the children's footwear models analyzed. According to these figures, they were ranked as Red Leather > White Leather > White Synthetic > Pink Synthetic, from best to worst.
