    随着经济的发展,资源短缺、环境污染等问题日益严重,人们的环境保护和节约意识不断增强。其中每年大量淘汰的废旧产品是造成资源浪费和环境污染加剧的重要原因,因此,人们开始关注废旧产品的回收和再利用问题。在这种背景下,再制造作为一种环保节约型的生产理念和制造方式受到了许多国家的重视,成为实现可持续发展最有效的途径之一。在对再制造的研究中,废旧产品回收模式的优化设计是一个比较重要的问题。国内外已有许多学者对这一问题进行了一定的研究,但大多数模型是建立在市场需求确定的基础上,对需求不确定的情况考虑较少。本文主要研究基于再造的不确定需求下产品回收模式选择问题。
    在第一章中,对国内外已有研究现状做了分析;在第二章中,概述了再制造闭环供应链的内涵及特点,并从制造企业的角度出发,讨论了目前应用较广的三种回收模式:制造商负责回收模式、零售商负责回收模式和第三方负责回收模式各自的优缺点;在第三章与第四章中,分别研究企业不确定需求下无差价时及有差价时再制造回收模式。在随机市场需求条件下,利用博弈理论分别构建了新产品和再造品有价差和无价差两种情况下制造商和零售商的决策模型。同时,通过运用数值分析方法,考察不同回收模式中制造商和零售商的最优决策和期望收益以及产品再造相关因素变化对它们的影响,以期为管理者在不确定需求下进行回收模式选择提供决策指导。 [英文摘要]:     With the development of economy, many issues have occurred increasingly, such as shortage of resource, environment pollution etc. And people’s awareness of environmental protection and resource saving have been intensified gradually. But, actually, many used products usually result in resource waste and environment pollution; therefore all of countries pay more attention to product recovery and reuse. In this situation, remanufacturing has been identified by more and more countries and become one of the most effective fashions to achieve sustainable development.
    To remanufacturing, optimization design of recycling model have become an important issue, many works have reflected such field. But most modes are built based on market demand certainty or the conditions of demand uncertainty are curtailed.
    The main purpose of this dissertation is to study product’s recycling modes based on remanufacturing with uncertain demand. In chapter 1, we review related literatures. The essence and characteristics of remanufacturing closed-loop supply chain are discussed and the three kinds of recycling modes from the point of manufacturing enterprises are analyzed in chapter 2. In chapter 3 and chapter 4, the choice of enterprise recycling different modes are discussed under random market demand for products, respectively. Based on the game theory, the decision-making model between manufacturers and retailers under two kinds products’ price different are studied respectively. At the same time, by using numerical analysis method, the optimal solution of the main players in remanufacturing closed-loop supply chain and the influence of changing remanufacturing related factors on them can be gained, which can offer support for policymaker selecting recycling modes.
