项目摘要

In this study, we have proposed a framework for product life cycle modeling, and developed a web-based infrastructure for integrating element technologies of LCE. Thereat, a structural function modeling method named IDEF0 (Integration Definition Zero) is employed to concern with the product life cycle modeling (PLCM). In practice, deciding a format to describe the model by using XML, we have developed a prototype system to manage various activities associated with the modeling. Using thus obtained model, at every stage of product life cycle, we can calculate quantity flows of raw material, intermediate products, by-products and main products in addition to the quantities related with environmental issues, e.g., energy, CO_2, etc.Furthermore, to give a framework that can deal with every kind of products and support a variety of decision making of every user associated with LCE, we provide an infrastructure and deployed the system by using the idea known as Web service architecture. That … More aims that every user can not only utilize the evaluation system but also become a provider of his/her own services.In addition, our interests are paid on providing element technologies that will often appear in the problem-solving regarding LCE as follow.(1) We developed a novel method for multi-objective optimization in terms of soft computing. The method named MOON^<2R> has very flexible modeling ability of value function, and can apply readily using the conventional single-objective optimization methods to solve various problems on LCE.(2) We have developed a prototype system supporting a strategic decision-making on disassembly for recycling and remanufacturing at design stage of product life cycle. Based on the information given at the design stage and the certain geometric shape of used product, it can decide automatically the optimal disassembly sequence, and evaluates the disassembly plan quantitatively under multiple objectives.(3) We have formulated logistic design optimization as a non-linear mixed integer programming, and developed a new and novel meta-heuristic method termed hybrid tabu search. The method will be applicable for a variety of problems closely related with environmental concerns, e.g., location of disposal site, collection site of bio-mass wastes, and so on. Less

在本研究中，我们提出了一个产品生命周期建模的框架，并开发了一个基于Web的基础设施，集成要素技术的生命周期。在此基础上，提出了一种结构化功能建模方法IDEF 0（IntegrationDefinitionZero），用于产品生命周期建模。在实践中，我们决定了一种格式来描述模型使用XML，我们已经开发了一个原型系统来管理与建模相关的各种活动。利用这样得到的模型，在产品生命周期的每个阶段，除了与环境问题有关的数量外，我们还可以计算原材料、中间产品、副产品和主要产品的数量流，例如，此外，为了提供一个能够处理各种产品和支持与LCE相关的每个用户的各种决策的框架，我们提供了一个基础设施，并使用称为Web服务架构的思想部署了系统。的 ...更多信息我们的目标是每个用户不仅可以使用评估系统，而且还可以成为他/她自己的服务提供者。此外，我们的兴趣是提供以下关于LCE的问题解决中经常出现的元素技术。(1)提出了一种基于软计算的多目标优化方法。该方法<2R>具有非常灵活的价值函数建模能力，可以很容易地应用于传统的单目标优化方法来解决LCE的各种问题。(2)我们开发了一个原型系统支持的战略决策拆卸回收和再制造的产品生命周期的设计阶段。该方法根据设计阶段给定的信息，根据已使用产品的几何形状，自动确定最优拆卸顺序，并对拆卸方案进行多目标定量评价。(3)我们制定了物流设计优化作为一个非线性混合整数规划，并开发了一种新的和新颖的元启发式方法称为混合禁忌搜索。该方法将适用于与环境问题密切相关的各种问题，例如，处置场的位置，生物质废物的收集地点，等等。减
